A line passes through the pointa (-8,8) and (12,7)
Answers
Answer: y= -1/20x + 38/5
or
y= -1/20x + 7.6
Step-by-step explanation:
y-y1 = m(x-x1)
m = 8-7 / -8 - 12 = 1/-20 = -1/20
y-8 = -1/20(x+8)
y=-1/20x - 8/20 + 160/20
y= -1/20x + 38/5
or
y= -1/20x + 7.6

A rectangular prism has dimensions x units, 2x units, and x 8 units. which expression represents the surface area of the prism? 8x 16 square units 16x 32 square units 10x2 48x square units 2x3 16x2 square units
Answers
The rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units
Volume of a rectangular prismThe formula for calculating the suface area of rectangular prism is expressed as:
A =2()
lw + wh + lh
where:
l is the lengthw is the widthh is the heightGiven the following parameters
l = x units
w = 2x units
h = x - 8 units
Substitute
S = 2(2x^2 + x^2 - 8x + 2x^2 - 16x)
S = 2(5x^2-24x)
S= 10x^2 - 48x square units
Hence the rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units

an experiment requires the population of the bacteria to reach 2 million before the experiment can begin. The reproduction rate of the bacteria can be modeled by the exponential equation Y= 8 times 7^x. About how many hours X will it take for the bacteria population to reach 2 million?
round your answer the the nearest hour
Answers
Answer:
about 6 hours
Step-by-step explanation:
[tex]8( {7}^{x} ) = 2( {10}^{6} )[/tex]
[tex] {7}^{x} = 250000[/tex]
[tex]x = \frac{ ln(250000) }{ ln(7) } = 6.39[/tex]
The about 6 hours the bacteria population to reach 2 million.
What is exponential equation?An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.
Given that the experiment requires the population of the bacteria to reach 2 million before the experiment can begin.
The reproduction rate of the bacteria can be modeled by the exponential equation,
y = 8 × 7ˣ.
So, according to the question,
8 × 7ˣ = 2 × 10⁶
7ˣ = 250000
x ≈ 6.4
Hence the about 6 hours the bacteria population to reach 2 million.

because you first do 3*4 =12 twice because there are two sides, and do 10*3 twice, and 10*4 twice, and add it all up.

Answer:
Option D, [tex]164\ units^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the front and back
[tex]A = l * w[/tex]
[tex]A = 10\ units * 4\ units[/tex]
[tex]A = 40\ units^2[/tex]
Step 2: Determine the area of the sides
[tex]A = l * w[/tex]
[tex]A = 3\ units * 4\ units[/tex]
[tex]A = 12\ units^2[/tex]
Step 3: Determine the area of the top and bottom
[tex]A = l * w[/tex]
[tex]A = 10\ units * 3\ units[/tex]
[tex]A = 30\ units^2[/tex]
Step 4: Determine the total surface area
[tex]SA = 2(40\ units^2) + 2( 12\ units^2) + 2(30\ units^2)[/tex]
[tex]SA = 80\ units^2 + 24\ units^2 + 60\ units^2[/tex]

A skateboarder leaves a 12-foot tall ramp with an initial vertical velocity of 8 feet per sen
function f(h) = -8t² +8t + 12 represents the height, h, in feet of the skateboarder after t seconds.
How many seconds was the skateboarder airbound
Answers
To answer this, we substitute 12 ft to the f(h) in the given equation,
f(h) = -8t² + 8t + 12 = 12
Subtracting 12 from both sides of the equation will give us an answer of,
-8t² + 8t = 0
Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second.
Answer:
Below in bold.
Step-by-step explanation:
When he lands h = 0 so
-8t^2 + 8t + 12 = 0
Solving for t
t = [-8 +/- sqrt(8^2 - 3*-6*12)] / -16
t = 1.82 seconds.
