Which function has an x-intercept of - 4 and a y-intercept of 3 when graphed?
The function that has an x-intercept of - 4 and a y-intercept of 3 when graphed is f(x) = 3/4x + 3
Intercepts of a lineThe x-intercept of a line is the point where the line crosses the x-axis while the y-intercept of a line is the point where the line crosses the y-axis.
For the x-intercept, y = 0
For the function f(x) = 3/4x + 3
0 = 3/4x + 3
0 = 3x + 12
-3x = 12
x = -4
This shows that the function has an x-intercept of -4
For the y-intercept, x = 0
For the function f(x) = 3/4x + 3
y = 3/4(0) + 3
y = 3
This shows that the function has an y-intercept of 3
Hence the function that has an x-intercept of - 4 and a y-intercept of 3 when graphed is f(x) = 3/4x + 3

Reason:
Going from x^2 to (x+5)^2 means we shift the graph 5 units to the left.
The +3 at the end shifts the parabola up 3 units. This is because we add 3 to each y value. For instance a point like (0,25) moves to (0,28)

Calculate the difference in the proportion of males and the proportion of females that smoke. Give your answer to 2 decimal places
The difference in the proportion of males and the proportion of females that smoke is 0.08
Missing informationIn a sample of 61 males, 15 smoke, while in a sample of 48 females, 8 smoke.
How to determine the proportion difference?The given parameters are:
Male Female
Sample 61 48
Smokers 15 8
The proportion is calculated using:
p = Smoker/Sample
So, we have:
Male = 15/61 = 0.25
Female = 8/48 = 0.17
The difference is then calculated as:
Difference = 0.25 - 0.17

What is the sum of the areas of circle C and circle D?
O 7π units²
O 14π units²
O49π units²
O 98π units²
Answer:
[tex]98 \pi \:\: \sf units^2[/tex]
Step-by-step explanation:
[tex]\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}[/tex]
From inspection of the given diagram, circle C and circle D both have a radius of 7 cm.
Therefore:
[tex]\implies \textsf{Area of circle C}=\pi (7)^2=49 \pi \:\: \sf cm^2[/tex]
[tex]\implies \textsf{Area of circle D}=\pi (7)^2=49 \pi \:\: \sf cm^2[/tex]
Therefore, the sum of the areas of circle and circle D is:
[tex]\implies \textsf{Area of circle C}+\textsf{Area of circle D}=49 \pi + 49 \pi = 98 \pi \:\: \sf cm^2[/tex]
The sum of the areas of the circles is 98π units².
The correct option is D.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
The formula for the area of a circle is A=πr², where A is the area and r is the radius.
For circle C, the radius is 7, so its area is A_C = π(7)² = 49π units².
For circle D, the radius is also 7, so its area is A_D = π(7)² = 49π units².
The sum of the areas is therefore:
A_C + A_D = 49π + 49π = 98π units²
Therefore, the answer is (D) 98π units².

determine how much Allison will spend on all the frozen treats.
Answer:
One possible answer is: 2.25p + 2.25b + 2.25s
Another possible answer: 2.25(p + b + s)
==========================================================
Explanation:
p = number of popsiclesb = number of ice cream barss = number of ice cream sandwichesEach item costs $2.25 per box, so,
2.25p = cost of just the popsicles only2.25b = cost of just the ice cream bars only2.25s = cost of just the ice cream sandwiches onlyAdd up those subtotals to get the grand total
2.25p + 2.25b + 2.25s
is one possible answer
What we can do is factor out the common 2.25 using the distributive rule in reverse.
Another possible answer is: 2.25(p + b + s)

Jaime makes the following claim.
An angle with a measure of π/3 radians in a circle with a radius of 3 inches is smaller than an angle with a measure of π/3 radians in a circle with a radius of 6 inches. This is because the radian measure is based on the length of the radius of the circle and a radius of 3 inches is smaller than a radius of 6 inches.
1. Review Jaime’s statement and what you know about angles and radians.
a. Explain whether you agree with Jaime’s statement or not.
b. Provide examples to support your whether you agree or disagree.
Jaime is incorrect, the angle does not depend on the radius of the circles.
Is Jaime correct?Remember that an angle that defines an arc on a circle, does not depend on the radius of the circle.
So, if we have an angle with a measure of π/3 radians in a circle with a radius of 3 inches and an angle with a measure of π/3 radians in a circle with a radius of 6 inches, these two angles are exactly the same thing.
The radius of the circle only has an impact on the length of the arc defined by the angle.
