Answer: g < 5
5 is the amount of gigabytes
Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.
The inequality representing the number of gigabytes Oliver can use while staying within his budget of $60 per month is:
3g + 45 ≤ 60.
where,
"g" represents the number of gigabytes used.
$3 is the cost per gigabyte.
$45 is the flat monthly cost.
$60 is the maximum budget.
Oliver pays a flat cost of $45 per month, which is represented by the constant term 45 in the inequality.
He also pays $3 per gigabyte, so the cost for the gigabytes used is 3g, where "g" represents the number of gigabytes.
The total cost (3g + 45) must be less than or equal to $60, as he wants to keep his bill under $60 per month.
Hence, the inequality is 3g + 45 ≤ 60.
Now, solve for g:
45 + 3g ≤ 60
Subtract 45 from both sides:
3g ≤ 15
Divide both sides by 3:
g ≤ 5
So, Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.

A circle that has (-2,4) and (4,2) as endpoints of a diameter.
Use the given information to write the standard equation of the circle.
I WILL MARK BRAINLIEST IF YOU GIVE ME THE CORRECT ANSWER!
Answer:
[tex]\implies (x-1)^2+(y-3)^2=10[/tex]
Step-by-step explanation:
End points of the diameter of the circle are:
[tex](-2,\:4) \implies x_1= -2, \: y_1= 4[/tex]
[tex](4,\:2) \implies x_2= 4, \: y_2= 2[/tex]
Equation of circle in diameter form is given as:
[tex](x-x_1)(x-x_2)+(y-y_1)(y-y_2)=0[/tex]
Plugging in the values of [tex]x_1, \: y_1,\:x_2, \: y_2[/tex] in the above equation, we find:
[tex][x-(-2)](x-4)+(y-4)(y-2)=0[/tex]
[tex]\implies (x+2)(x-4)+(y-4)(y-2)=0[/tex]
[tex]\implies x^2-2x-8+y^2-6y+8=0[/tex]
[tex]\implies x^2-2x+1-9+y^2-6y+9-1=0[/tex]
[tex]\implies (x^2-2x+1)-9+(y^2-6y+9)-1=0[/tex]
[tex]\implies (x-1)^2+(y-3)^2-10=0[/tex]
[tex]\implies (x-1)^2+(y-3)^2=10[/tex]

The 25th term of an arithmetic series is 44.5
The sum of the first 30 terms of this arithmetic series is 765
Find the 16th term of the arithmetic series.
Show your working clearly.
Answer:
[tex]a_{16}=26.5[/tex]
Step-by-step explanation:
Arithmetic series: [tex]a_n=a+(n-1)d[/tex]
Sum of arithmetic series: [tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
(where a is the first term and d is the common difference)
Given:
[tex]a_{25}=44.5[/tex][tex]S_{30}=765[/tex][tex]\implies a_{25}=44.5[/tex]
[tex]\implies a+(25-1)d=44.5[/tex]
[tex]\implies a+24d=44.5[/tex]
[tex]\implies S_{30}=765[/tex]
[tex]\implies \dfrac{30}{2}[2a+(30-1)d]=765[/tex]
[tex]\implies 30a+435d=765[/tex]
Rewrite [tex]a+24d=44.5[/tex] to make a the subject:
[tex]\implies a=44.5-24d[/tex]
Substitute found expression for a into [tex]30a+435d=765[/tex] and solve for d:
[tex]\implies 30(44.5-24d)+435d=765[/tex]
[tex]\implies 1335-285d=765[/tex]
[tex]\implies 285d=570[/tex]
[tex]\implies d=2[/tex]
Substitute found value of d into [tex]a=44.5-24d[/tex] and solve for a:
[tex]\implies a=44.5-24(2)=-3.5[/tex]
Therefore:
[tex]\implies a_{16}=-3.5+(16-1)2=26.5[/tex]

Step-by-step explanation:
1.
a. true
b. false (the arc angles are relative to the center of the circle)
c. true (as the central angle of a circle is twice any inscribed angle subtended by the same arc)
d. true (but note that the arc angle of YE is again measured via the center of the circle and twice as large as the angle S)
2.
EGS is an isoceles triangle (that means both legs are equally long).
remember the extended Pythagoras for general triangles :
c² = a² + b² - 2ab×cos(C)
c being the side opposite of the angle C.
let's say c is our long baseline, since we have is opposite angle 124°, and a = b = GE = GS, we have
3.8² = a² + a² - 2aa×cos(124) = 2a² - 2a²×cos(124) =
= 2a²(1 - cos(124))
2a² = 3.8²/(1 - cos(124))
a² = 3.8²/(2(1 - cos(124)))
a = GS = sqrt(3.8²/(2(1 - cos(124)))) =
= 2.151883096... ≈ 2.2 cm
3.
circumference
16pi = 2pi×r
r = 8
area = pi×r² = pi×8² = 64pi
yes, the statement is true.
4.
a half-circle has 180°.
the arc angel AD is a full half-circle (because AD is a diameter), so it is 180°.
the angle ACB is the arc angle AB = 40°. so, the arc angle BD must be the rest of the 180° = 180 - 40 = 140°.
5.
diameter = 50 ft.
so, the radius or distance from the center to the circle arc is 50/2 = 25 ft.
the length of a chord is
c = 2×sqrt(r² - d²)
with r being the radius, d being the distance of the chord from the center.
40 = 2×sqrt(25² - d²)
20 = sqrt(625 - d²)
400 = 625 - d²
-225 = -d²
225 = d²
d = 15 cm
so, the distance of the chord from the center is 15 cm.
6.
the arc angles RE and TS are equal. that means the arc lengths of RE and TS are equal.
and that means the arc lengths of RS and ET are equal. the chords between 2 points on a circle must have the same length, when the arc lengths between these 2 points are the same.
7.
they are equally long.
as we saw in 5., the length of a chord depends on the radius of the circle and the distance of the chord from the center.
since both chords are in the same circle (with the same radius), and they both have the same distance from the center, they can only be equally long, as there is no other element to name them different.
8.
the angle NPE is half of the angle NAE (= the arc angle NE).
the arc angle NE = 63×2 = 126°
the angle PET is half of the angle PAT (= the arc angle PT).
the arc angle PT = 19×2 = 38°
the arcs NP and ET cover the rest of the whole circle circumference (360°).
so, arc angle NP + arc angle ET = 360 - 38 - 126 = 196°
but arc angles NP and ET must be equal (as per the problem definition).
therefore, 2 equal arc angles = 196°
1 arc angle = NP = 196/2 = 98°

Given: x1 = 6, x2 = 2.5, y1 = 2.4. Find y2 if the points are (a) directly proportional or
(b) inversely proportional
a) The value of y₂ is 1 for the direct proportionality case.
b) The value of y₂ is 5.76 for the inverse proportionality case.
How to predict a value by apply proportionality model
Proportionality represents a family of relationships between two variables, which can be linear and nonlinear. Direct proportionality represents a linear relationship, whereas inverse proportionality represents a kind of nonlinear relationship.
Here are two mathematical representations of the relationships described above:
Direct proportionality[tex]y \propto x[/tex]
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex] (1)
Inverse proportionality[tex]y \propto \frac{1}{x}[/tex]
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{1}}{x_{2}}[/tex] (2)
If we know that x₁ = 6, x₂ = 2.5, y₁ = 2.4, then the value of y₂ for each case are, respectively:
Direct proportionalityy₂ = 2.4 × (2.5/6)
y₂ = 1
Inverse proportionalityy₂ = 2.4 × (6/2.5)
y₂ = 5.76

The lender’s good faith estimate is that he made a poor estimate; it was off by more than 0.5% of the actual closing costs.
What is closing cost?All the expenduture and charges charged by a lander and other parties is called the closing cost.
A lender estimates the closing costs on a home loan will be 3.75% of the loan amount of $120,000. Thus, the estimate closing cost is,
[tex]C_{ec}=\dfrac{3.75}{100}\times120000\\C_{ec}=4500[/tex]
The actual closing costs are listed below.
Loan origination $300Title insurance $600 Attorney’s fees $1,250 Appraisal $550 Inspection $525 Recording fees $125 Escrow $2,000.The total annual cost is,
[tex]C= $300 +$600 +$1,250 +$550 +$525 +$125 +$2,000\\C=4800[/tex]
Total annual cost is $300 more than the estimate closing cost. In the percentage form,
[tex]p=\dfrac{4800-4500}{4500}\times100\\p=6.66\%[/tex]
Thus, the lender’s good faith estimate is that he made a poor estimate; it was off by more than 0.5% of the actual closing costs.

What is the equation?
Answer:
1) [tex]y=x^2+2[/tex]
2) [tex]y=x^2-4[/tex]
3) [tex]y=x^2[/tex]
4) [tex]y=x^2+6x+14[/tex]
Step-by-step explanation:
Question 1
Given points: (-2, 6) (-1, 3) (0, 2) (1, 3)
This is likely to be a quadratic equation with a vertex of (0, 2) since the points (-1, 3) and (1, 3) are symmetrical about x = 0
Vertex form of quadratic equation: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)
[tex]\implies y=a(x-0)^2+2[/tex]
[tex]\implies y=ax^2+2[/tex]
To find a, input one of the points into the equation:
[tex](1, 3)\implies a(1)^2+2=3\implies a=1[/tex]
Therefore, the equation of the graph is [tex]y=x^2+2[/tex]
Question 2
If the parabola intersects the x-axis at (-2, 0) and (2, 0) then
[tex]y=a(x+2)(x-2)[/tex]
We are told that the y-intercepts if (0, -4). Input this into the equation to find a:
[tex]\implies a(0+2)(0-2)=-4[/tex]
[tex]\implies -4a=-4[/tex]
[tex]\implies a=1[/tex]
Therefore,
[tex]\implies y=(x+2)(x-2)[/tex]
[tex]\implies y=x^2-4[/tex]
Question 3
Given points: (-2, 4) (-1, 1) (0, 0) (1, 1)
This is likely to be a quadratic equation with a vertex of (0, 0) since the points (-1, 1) and (1, 1) are symmetrical about x = 0
Vertex form of quadratic equation: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)
[tex]\implies y=a(x-0)^2+0[/tex]
[tex]\implies y=ax^2[/tex]
To find a, input one of the points into the equation:
[tex](-2,4)\implies a(-2)^2=4\implies a=1[/tex]
Therefore, the equation of the graph is [tex]y=x^2[/tex]
Question 4
[tex]f(x) = x^2 + 5[/tex]
If we wish to move the function to the left by 3 units, we substitute x for [tex]x+3[/tex]:
[tex]\begin{aligned}\implies f(x+3) & =(x+3)^2+5\\ & = x^2+6x+9+5\\ & = x^2+6x+14\end{aligned}[/tex]

Amy fills an ice cream cone to the top edge. The diameter of the ice cream cone is 2 inches and its height is 6 inches. Don fills a bowl (V = 5 cubic inches) with ice cream. Amy has how much more ice cream than Don?
Answer:
1.28 in³
Step-by-step explanation:
Volume of Amy's cone
Cone = 1/3πr²hCone = 1/3 x 3.14 x 1² x 6Cone = 2 x 3.14 = 6.28 in³Volume of Don's bowl
It's given to be 5 in³Difference
Amy's cone - Don's bowl6.28 - 51.28 in³Answer:
So obviously in the context of this question you are meant to find the volume. Since Don's bowl already has a given value of 5 cubic inches we will use that same unit when calculating amy's ice cream cone volume.
Step-by-step explanation:
You are given that amy has a cone and need to find the volume. The formula for the volume of a cone is (V=πr^2*h/3).
π = pi or 3.14......
r = radius (in this case the opening/ diameter of the ice cream cone is given as 2 inches and the radius is half of diameter so d/2 = r (r=1)
h = height (in this case it is given that height is 6 inches)
Remember all variable units must be kept the same so in this case all units are inches.
Now Plug in and solve V = [tex]3.14*(1)^{2} *\frac{(6)}{3}[/tex]
Remember order of operations / PEMDAS (in this case, do exponent first then just multiply from left to right and at the end divide that number by 3.
V= 6.28 cubic inches (since all our units were inches and we are finding cubic volume of a cone)
Now Amy volume of cone - Don volume of bowl = your answer. 6.28-5 = 1.28 cubic inches
