(-4, 12) and (-7, -3) write an equation of the line in slope intercept form that passes through the points.
Answer:
The equation in slope-intercept form is: [tex]y=5x+32[/tex]
Step-by-step explanation:
To calculate the slope, [tex]m[/tex], we use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex] where [tex]y[/tex] are the [tex]y[/tex]-values of the points and [tex]x[/tex] are the [tex]x[/tex]-values.
Pugging our numbers into the formula, we get [tex]\frac{(-3)-12}{-7-(-4)}[/tex]. This simplifies to 5.
To calculate the [tex]y[/tex]-intercept, we first substitute one of our points into the formula. Substituting -4 and 12, we get [tex]12=5(-4)+b[/tex].
Then we can solve for [tex]b[/tex].
[tex]12=5(-4)+b[/tex]
[tex]12=-20+b[/tex]
[tex]32=b[/tex]
So, our slope is 32.
We can then plug these values into the slope-intercept form [tex]y=mx+b[/tex]
A machinist is required to manufacture a circular metal disk with area 600 cm2 . (a) What radius produces such a disk? (b) If the machinist is allowed an error tolerance of ±5cm2 in the area of the disk, how close to the ideal radius in part (a) must the machinist control the radius? (c) In terms of the limit limx→a f(x) = L, what is f(x)? What is a? What is L?
The required radius and error in radius is 13.8 cm and ± 0.12cm
Given that,
A machinist is required to manufacture a circular metal disk with an area of 600cm².
(a) What radius produces such a disk is to be determined
(b) If the machinist is allowed an error tolerance of ±5cm2 in the area of the disk, how close to the ideal radius in part is to be determined.
The area of a circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
a) The given area of disk = 600 cm²
πr² = 600
r = √600/3.14
r = 13.8 cm
b) an error tolerance of ± 5 cm² in the area of the disk,
So the percentage of error is 0.84%
Now, 0.84% of radius = 0.84 *13.8/100 = 0.12
The required error in radius will be ±0.12 cm
Similarly,
c) limx→a f(x) = L
Where a is the area of the disk and L is length, and f(x) is function of area.
Thus, the required radius and error in radius is 13.8 cm and ± 0.12cm.

Part A
Callie kicks a soccer ball from the ground. The height of the ball, in feet, above the ground t seconds after the ball is kicked can be represented by the expression 38t- 16t². Write the expression in factored form.
Part B
What is the height of the soccer ball 1.25 seconds after Callie kicks it?
______ feet
Part A The quadratic expression in factored form is 2t(19 - 8t)
Part B The height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft
Part A Write the expression in factored form.Since Callie kicks a soccer ball from the ground. The height of the ball, in feet, above the ground t seconds after the ball is kicked can be represented by the expression 38t- 16t².
So, the expression is a quadratic expression, we have that h(t) = 38t- 16t².
To write the expression in factored form, we find the common factors of both terms and factor them out.
So, h(t) = 38t- 16t²
= 2 × 19 × t - 2 × 8 × t × t
Factoring out 2 and t, we have
= 2 × t × (19 - 8 × t)
= 2t(19 - 8t)
So, the quadratic expression in factored form is 2t(19 - 8t)
Part B What is the height of the soccer ball 1.25 seconds after Callie kicks it?Since the quadratic expression h(t) = 38t- 16t² represents the height of the ball above the ground in feet, to find the height of the ball after 1.25 second,we substitute t = 1.25 s into the expression.
So, h(t) = 38t- 16t²
h(1.25) = 38(1.25) - 16(1.25)²
h(1.25) = 47.5 - 16(1.5625)
h(1.25) = 47.5 - 25
h(1.25) = 22.5 ft
So, the height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft

Colton bought some strings of beads. The number of strings was 10 more than the number of beads on each string. There were 119 beads in all. How many strings of beads did Colton buy?
Answer: 17 strings
Step-by-step explanation:
let the number of strings be a
let the number of beads on each string be b
a − b = 10 (first equation)
a × b = 119 (second equation)
From the first equation:
a = 10 + b
substitute first equation into second equation
b × (10 + b) = 119
10b + b² − 119 = 0
b = 7 or b = -17 reject -17
a − 7 = 10
a = 17

A small plant is 212 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week? Which method will NOT give the correct number of inches?
The small will grow 19/4 inch in 3 weeks and the method which will not give the correct inches will be the first option which is
multiply [tex]2\frac{1}{2} * 3[/tex] and then add 3/4.
According to the question we have been given that
The height of the small plant = [tex]2\frac{1}{2}[/tex] inch
In 1 week the plant grows = [tex]\frac{3}{4}[/tex] inch
We need to find the height of the small plant after 3 weeks.
For that we will first find how much tall it will be in 3 weeks using unitary method that is,
1 week = [tex]\frac{3}{4}[/tex] inch
3 week = [tex]\frac{3}{4}[/tex] * 3 inch
= 9/4 inch
Therefore the height of the small plant after 3 weeks will be
[tex]=2\frac{1}{2} + \frac{9}{4} \\= \frac{5}{2} + \frac{9}{4}\\= \frac{10+9}{4} \\= \frac{19}{4}[/tex]
hence the height is 19/4 inch

Answer:
22, 24
Step-by-step explanation:
Hello!
Consecutive integers are integers that come after each other. We want to find two consecutive even integers that when added give us 46.
Let the first consecutive even integer be x. Since even integers come every 2 integers (even, odd, even), the second even integer should be x + 2.
Solve for xx + x + 2 = 462x + 2 = 462x = 44x = 22That means x + 2 should be 24.
The two numbers are 22 and 24.

A chemist mixes 225 milliliters of a solution that is 39% acid with 25 milliliters of a solution that is 19% acid.
Answer the questions below. Do not do any rounding.
(a) How many milliliters of acid are in the resulting mixture?
milliliters
(b) What percentage of the resulting mixture is acid?
0%
Part a: Resulting mixture: 92.2 milliliters.
Part b: Percentage of acid in the resulting mixture = 36.88%.
What is defined as the percentage?A percentage is a segment of a whole represented as a number between 0 or even 100 instead of as a fraction. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent. To calculate a percentage, divide the fraction of the total by the total and multiply by 100.Part a: Find the both values from the given percentage;
225 millilitres of a solution contains is 39% acid.
39% of 225 = (39×225)/100 = 87.75 millilitres.
Now, 25 milliliters of a solution contains is 19% acid.
19% of 25 = (19×25)/100 = 4.75 millilitres.
Mixture solution = 87.75 + 4.75
Mixture solution = 92.2 milliliters of acid.
Part b: percentage of the resulting mixture is acid.
92.2 milliliters of the total 250 milliliters is acid.
= 92.2/250 × 100
= 36.88 %
Thus, 36.88% of the the resulting mixture contains acid.

(Simplify your answer.)
If total revenue given by the function R=16.5x and has total cost given by C=14x+400, where x is the number of items produced and sold then the number of units that gives break even for the product is 160.
What is function?In mathematics, a function is an expression, rule, or law that specifies a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are commonplace in mathematics and are required for expressing physical relationships in the sciences. The present concept of function was proposed by German mathematician Peter Dirichlet in 1837.
If a variable y is so tied to a variable x that there is a rule that determines a unique value of y whenever a numerical value is assigned to x, then y is referred to as a function of the independent variable x.
If the manufacturer will break even for the products then
Revenue = Cost
F(R) = F(C)
14x+400 = 16.5x
On solving the equation
16.5x - 14x = 400
2.5x = 400
x = 400/2.5
x = 160

During a person's commute to school, she spends 12 minutes driving 35 mph and 3 minutes stopped at red lights. What is the person's average
speed during her commute?
Step 1 of 2: First, find the distance of her commute.
The average speed of person during her commute is 28 miles/ hour.
What do you mean by average speed ?
The entire distance that an object travels in a given amount of time is defined as the average speed for that object.
Total time of driving is 12 minutes.
This can be written as hours which will be :
= 12 / 60
= 1/5 hour
Time of stopping at red lights is 3 minutes and speed is 35 miles per hour.
So , the total distance using the formula will be :
Total distance = Speed × time
Here , the time taken will be equal to :
= [(12 + 3) / 60]
= 15 / 60
= 1/4 hour
So ;
Total distance = 35 × (1/4 hour)
Total distance = 7 miles
And the average speed will be ;
Average speed = Distance / Time
or
Average speed = 7 miles / (1/4) hour
Average speed = 7 × 4 miles/hour
Average speed = 28 miles / hour
Therefore , the average speed of person during her commute is 28 miles/ hour.

There are 6 black marbles and 4 red marbles in a jar. If you add 4 red marbles to the jar, how many black marbles do you need to add to keep the ratio of black marbles to red marbles the same?
You need to add 6 red marbles for the ratio to stay the same
How many black marbles do you need to add?The given parameters are:
Black = 6
Red = 4
Represent as ratio
Ratio = Red : Black
This gives
Red : Black = 4 : 6
When you add 4 red marbles, we have:
4 + 4 : 6 + x = 4 : 6
Where x represents the additional number of black marbles
This gives
8 : 6 + x = 4 : 6
Multiply 4 : 6 by 2
So, we have:
8 : 6 + x = 8 : 12
