Graph the line with slope -1/2 passing through the point (-1,-2)
Answers
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]m = -\frac{1}{2}[/tex]
[tex](x_1,y_1) = (-1,2)[/tex]
Required
Graph the line
First, is to determine the equation of the line using:
[tex]m = \frac{y - y_1}{x - x_1}[/tex]
So:
[tex]-\frac{1}{2} = \frac{y - 2}{x - -1}[/tex]
[tex]-\frac{1}{2} = \frac{y - 2}{x +1}[/tex]
[tex]\frac{-1}{2} = \frac{y - 2}{x +1}[/tex]
Cross multiply:
[tex](y -2) * 2 = -1 * (x + 1)[/tex]
[tex](y -2) * 2 = -x -1[/tex]
Solve for y - 2
[tex]y -2 = -\frac{x}{2} -\frac{1}{2}[/tex]
Solve for y
[tex]y = -\frac{x}{2} -\frac{1}{2} + 2[/tex]
[tex]y = -\frac{x}{2} +\frac{-1+4}{2}[/tex]
[tex]y = -\frac{x}{2} +\frac{3}{2}[/tex]
The above equation will then be plotted on the graph (See attachment)

find the total surface area of the following cone. leave your answer in terms of pi.
Answers
Answer:
90pi
Step-by-step explanation:
SA = pi r l +B
we know the radius is 5
We need to find the slant height using the Pythagorean theorem
a^2+b^2 = c^2
5^2+12^2 = l^2
25+144= l^2
169 = l^2
Taking the square root of each side
sqrt(169) = sqrt(l^2)
13 = l
B is the area of the base
B = pi r^2 = pi (5)^2 = 25 pi
SA = pi r l +B = pi (5)*13 + 25pi
=65pi +25pi = 90pi
Answer:
90 pi
Step-by-step explanation:
Just in case the other answer was confusing. Just put it in, and it marked it right. 90 is the answer

Step-by-step explanation:
Given that,
The height of a cylinder, h = 8 inches
The diameter of the cylinder, d = 14 inches
Radius, r = 7 inches
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\=\dfrac{22}{7}\times 7^2\times 8\\\\V=1232\ inches^3[/tex]

C. Equation:4+12x=40
D. Answer:$7
Answers
Answer:
D. $7
Step-by-step explanation:
i think it would be "D". the reason why i chose that answer is because first of all the total they spent is $40 right? as we see in this equation, paige and her family purchased $12 for popcorn. what does that mean? it means that 40-12= $28 that is left. the money that is left is the total of all 4 tickets. 28 divided by 4 is 7 so the answer is $7

Ball thrown straight up
H(x)=64x-16xSquared
How do you find the value of x when the ball reached its maximum height.
Answers
Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
Find the value of x when the ball reaches its maximum height.
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
a = -16b = 64c = 0Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
-(64)/2·(-16) -64/-32 2The vertex of the parabola is at x = 2, with a maximum height of H(2).
