Maru makes an initial down payment of \${3000}
$3000
, then repays \${70}
$70
per week.
Calculate how many weeks it takes Maru to fully pay off $43000.
pls help me with this asap
The number of weeks that it'll take Maru to fully pay off $43000 is 571.4 weeks.
How to calculate the value?From the information, Maru makes an initial down payment of $3000 then repays $70 per week and the total amount is $43000.
Let the number of weeks be represented as w.
This will be illustrated as:
3000 + (70 × w) = 43000
3000 + 70w = 43000
Collect like terms
70w = 43000 - 3000
70w = 40000
Divide
w = 40000 / 70
w = 571.4
The number of weeks is 571.4 weeks

two, or no real zeros? Utilize the
quadratic formula to determine
the answer.
[?] real zero(s)
The given quadratic function has two real zeros.
We are given a function. The function is quadratic in nature. We need to check whether the given quadratic function has one, two, or no real solutions. We will use the quadratic formula to determine the answer. The equation of the quadratic function is given below.
f(x) = 4x² + 5x - 29
The general form of a quadratic equation is ax² + bx + c. The values of the variables a, b, and c for the given equation are 4, 5, and -29, respectively. The quadratic formula is given below.
x = (-b ± √D)/2a
The variable "D" represents the discriminant of the quadratic equation. If the value of D is less than zero, then no real roots exist. If the value of D is equal to zero, then only one real root exists. If the value of D is greater than zero, then two real roots exist. The formula for discriminant is D = b² - 4*a*c. We will calculate the discriminant for the given equation.
D = b² - 4*a*c
D = 5² - 4*(4)*(-29)
D = 25 + 464 = 489
The value of the discriminant is positive, so the function has two real roots.

If 1200 square centimeters of material is available to make a box with a square base and an open top, find the largest possible volume of the box.
The largest possible volume V is 4000[tex]cm^3[/tex]
Given,
Volume of a box = length × breadth × height= l× b× h
In this case the box have a square base. i.e., l = b
Volume V = [tex]l^2[/tex] × h
We using the formula of Surface area
The surface area of a square box
S = 2(lb +lh+ bh)
S = 2([tex]l^2[/tex] + lh + lh) since l=b
S = 2([tex]l^2[/tex] + 2lh)
Also, Given that the box is open top.
S = [tex]l^2[/tex] +4lh
And Surface Area of the box is 1200cm^2
1200 = [tex]l^2[/tex] + 4lh ....1
Making h the subject of formula
h = (1200 - [tex]l^2[/tex])/4l .....2
Volume is given as
V = [tex]l^2[/tex] × h
V = [tex]l^2[/tex] ×(1200 - [tex]l^2[/tex])/4l
V = (1200l - [tex]l^3[/tex])/4
the maximum point is at dV/dl = 0
dV/dl = (1200 - [tex]31^2[/tex])/4
dV/dl = (1200 - [tex]31^2[/tex])/4 = 0
[tex]31^2[/tex]= 1200
[tex]l^2[/tex] = 1200/3 = 400
l = √400
I = 20cm
Since,
h = (1200 - [tex]l^2[/tex])/4l
h = (1200 - [tex]20^2[/tex])/4×20
h = (800)/80
h = 10cm

A toy rocket is shot vertically into the air from a launching pad 7 feet above the ground with an initial velocity of 72 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=-16 t²+72 t+7. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at ? second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is ? feet.
(Simplify your answer.)
The rocket reaches its maximum height of 88 feet at 2.25 seconds after launch
How to find the time and the maximum heightThe time
The function is given as
h(t) = -16t² + 72t + 7
To start with, we need to differentiate the function
h'(t) = -32t + 72
Next, we set the differentiated function to 0
-32t + 72 = 0
Next, we solve for the variable t
t = 2.25
This means that the time is 2.25 seconds
The maximum height
Recall that we have the value of t to be:
t = 2.25
Also, we have the equation to be
h(t) = -16t² + 72t + 7
So, we have
h(2.25) = -16(2.25)² + 72(2.25) + 7
Solve the expressions
h(2.25) = 88
This also means that the maximum height is 88 feet

in the exponential function g(x)=a(b)^x it is known that g(3)=25 and g(7)=3
By solving a system of equations we will see that the exponential function is:
g(x) = 122.347*(0.589)^x
How to find the exponential function?We know that our function is of the form:
g(x) = a*(b)^x
We also know that g(3)=25 and g(7)=3, then we can write:
a*(b)^3 = 25
a*(b)^7 = 3
So we have a little system of equations.
Taking the quotient between the second and first equations we get:
(a*(b)^7)/(a*(b)^3) = 3/25
b^4 = 3/25
b = (3/25)^(1/4) = 0.589
Replacing that in the first equation we get:
a*(b)^3 = 25
a*(0.589)^3 = 25
a = 25/(0.589)^3 = 122.347
The exponential function is:
g(x) = 122.347*(0.589)^x

Use and algebraic equation to find the measure of each angle that is represented in terms of x
The measurement of each angle represented in terms of x is 156°
What is the angle measurement?Here given the two angles : (13x-26)° and (9x+30)°.
We have to find each angle measurement.
From the given figure, it is clear that two angles are just vertically opposite angles.
So , we know that vertically angles are equal
So to find angles , we have to find x.
13x - 26 = 9x + 30
13x - 9x = 30 + 26
4x = 56
x = 56 / 4
x = 14
So the value of x = 14
Then we have to substitute the value of x in any of the given measurement.
By substituting x in (13x - 26)°
13 x 14 - 26
182 - 26
= 156
Similarly by substituting x in (9x + 30) °
9 x 14 + 30
= 126 + 30
= 156°
Therefore, the measurement of each angle is 156°.

The units price are:
For brand A: $0.0796For brand B: $0.0926Then brand A is the better option.
How to find the unit price?If you know that a set of N items has a price P, then the unit price is given by the quotient between the price and the number of items that you get, N.
For Brand A, we know that there are 25 spoons for $1.99, then in this case the unit price is:
a = $1.99/25 = $0.0796
For Brand B the set has 42 spoons for $3.89, then the unit price is:

The expression that represents the amount in dollars that each paid is (a) 1.2s - 1.2.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, Su's Sushi is $2 more than Darbi sushi and the cost of Su's sushi is represented by s.
Let the price of Darbi's sushi is $x.
Then, the price of Su's sushi is
s = x + 2
x = s -2
The total cost is:
x + s
= s -2 + s
= 2s -2
Since they divided the total cost evenly, the cost each paid is:
(2s-2)/2
= s -1
Now, the cost after paying a 20% tip is:
(s - 1) + 20% of (s - 1)
= s- 1 + 20(s-1)/100

The variable g has its value to be -4 on the given coordinate point
How to calculate the value of point G of the line?From the question, the points are given as
(g, -1) and (2, 5)
Rewrite the above points properly
So, we have the following ordered pairs
(x, y) = (g, -1) and (2, 5)
The slope of the line is given as
Slope = 3/2
The slope of the line is then calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (g, -1) and (2, 5)
Substitute the known values in the above equation
So, we have the following equation
3/2 = (5 + 1)/(2 - g)
Evaluate the sum in the equation
This gives
3/2 = 6/2 - g
Cross multiply
So, we have
2(2 - g) = 12
Divide by 2
2 - g = 6
Make g the subject of the formula
g = 2 - 6
