The equation which represents the change in elevation of the mountain climber as he descends the cliff is; c = -2.5s.

<h3>What is the change in elevation c of the climber in terms of seconds?</h3>

It follows from the task content that the change in elevation of the climber is to.be represented by c and since the rate of descending the cliff is given as; 2.5 ft/second.

Therefore, the required equation is; c = -2.5s.

Write an equation in slope-intercept form for the line with slope 8 and y-intercept -8.​
Fofino [41]

Answer:

y = 8x - 8

Step-by-step explanation:

y = mx + b is slope-intercept form

m - slope

b - y-intercept

so if you plug in 8 for m and -8 for b you'll get

y = 8(m)x - 8(b)

Hope this helps!!

Evaluate each expression if a = 6, b = 3, and c = 2.
earnstyle [38]

Answer:

a = 6, b = 3, and c = 2

1. ab1 = 6 × 3 × 1 = 18

2. c + 42 = 2 + 42 = 44

3. 18 = 18

4. a − b4  = 6 - 3(4) = 6 - 12 = - 6

5. 2c3 = 2 × 2 × 3 = 12

6. b ÷ 35 = 3÷35 = 0.086

7. a − 1 6 =  6 - 16 = -10

8. 6 + c8 = 6 + 2 (8) = 6 + 16 = 22

An observer, whose eyes are 1.98 m above the ground, is standing 39.2 m away from a tree. The ground is level, and the tree is g
lozanna [386]

Answer:

The tree is 16.25 m tall.

Step-by-step explanation:

Attached is a diagram that better explains the problem.

From the diagram we see that the distance between the top of the tree and the line of sight of the observer is x.

To find the height of the tree, we need to first find x and then add it to the height of the observers line of sight from the ground.

Using SOHCAHTOA trigonometric function:

tan(20) = x/39.2

=> x = 39.2 * tan(20)

x = 39.2 * 0.364

x = 14.27m

Hence, the height of the tree is:

(14.27 + 1.98)m

16.25m

The tree is 16.25 m tall.

Alice Correa bought three yards of cloth to make a dress the cloth was on sale for a dollar 93 per yard how much did Alice pay f
alexandr1967 [171]
To solve for the total amount that Alice paid for the 3 yards cloth, multiply the cost per yard with the additional 5% to number of yards. 5% of 93 is 4.65. The total cost per yard of cloth is 97.65. Multiplying the total cost with 3 will give 292.95. Thus, Alice paid 292.95 dollars in total.
