inysia [295]3 years ago

Answer:

Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

Step-by-step explanation:

It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

We need to find the meaning of V(2)=T.

On comparing V(d) and V(2), we get d=2.

Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.

V(2)=T

It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

14. The sum of the digits of a certain two-digit number is 4. When you reverse its digits you decrease the number by 18. What is
kipiarov [429]

Step-by-step explanation:

If the tens digit of the number is X and the ones digit is Y then the number is equal to 10*X + Y

If you reverse the digits then the number is equal to 10*Y + X

If reversing the digits decreases the number by 36 then

10*Y + X = 10*X + Y - 36

The sum of the digits is 4 so X + Y = 4 ==> X = 4 - Y

Substitute this value of X into the 1st equation

10*Y + (4 - Y) = 10*(4 - Y) + Y - 36

9*Y + 4 = 40 - 9*Y - 36

18*Y = 0

Y = 0

I hope it helps you

So X = 4 - 0 = 4 and the number is 40

so, let's check 40 - 04 = 36

A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid i
Temka [501]

Answer:

9.48

Step-by-step explanation:

Complete question

<em>A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the​ pyramid?</em>

To get the height of the pyramid, we will use pythagoras theorem.

slant height l is the hypotenuse

length of the base is the adjacent

height of the pyramid is the opposite

According to the theorem;

l² = h² + b²

90.1² = h² + 89.6²

8,118.01 = <em>h²+</em>8,028.16

h²= 8,118.01 - 8,028.16

h² = 89.85

h =√89.85

h = 9.48

Hence the height of the pyramid will be 9.48

<em>Note that the value of the slant height was assumed to solve the problem</em>.
