Answer:

A. 49 + 16 (t - 1)

Step-by-step explanation:

Plug in t = 1 to test for the first hour:

$49+16(1-1)=49+16(0)=49$

Test as many values as you like, but testing t = 5:

$49+16(5-1)=49+16(4)=49+64=113$

You can see that plugging in just a few values confirms the answer.

Answer:

Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph $y= \frac {2}{5} x - 3$ is below

$y = - \frac {5}{2} x + 2$

Step-by-step explanation:

Slope of the equation $y= \frac{2}{5} x -3$ is $m_1 = \frac{2}{5}$

Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

$m_2 = - \frac {1}{m_1} = - \frac {5}{2}$

Equation of line in point slope form is given as

$y-y_1=m_2(x-x_1)$

Here (x1, y1) = (4, -8)

$y+8 = - \frac{5}{2} (x-4)$

Simplifying it further

$y = - \frac {5}{2} x + \frac {5}{2} 4 - 8$

$y = - \frac {5}{2} x + 2$

What is the solution set for 7x – 3 = 18, given the replacement set {0, 1,2,3,4} ? O

yawa3891 [41]

Answer:

X = 3

Step-by-step explanation:

Given the expression :7x - 3 = 18

To obtain the solution set ; we solve for X in the equation ;

7x - 3 = 18

Add 3 to both sides

7x - 3 + 3 = 18 + 3

7x = 21

Divide both sides by 7

7x / 7 = 21 / 7

x = 3

Hence, x = 3

A lighthouse beacon can be seen 17mi in all directions. To the nearest square mile, what is the area over which the beacon can b

Alchen [17]

Imagine this as a circle. The circle will have a radius of 17mi and the lighthouse will be in the middle. The area of the circle will be the area over which the beacon can be seen.

$A=\pi r^{2}$ is the equation for the area of the circle where A is the area.

Now we simply plug in our information

A= $\pi (17)^{2}$
A=907.9 $mi^{2}$
