Mathematics
1 answer:
Leviafan [203]2 years ago
5 0

Answer:

h = 3.6

Step-by-step explanation:

This is just substituting in for variables and solving for x. The hard part is knowing the formula.

R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.

Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.

(8.1) = h(((1) + (3.5)) / 2)

= h((4.5) / 2)

= h(2.25)

8.1/2.25 = h

3.6 = h

Answer:

Step-by-step explanation:

f(-9+h)= (-9+h)² = h²-18h+81

f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81

f(-9+h)-f(-9)=h²-18h

(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18

lim  (f(-9+h)-f(-9))/h = lim(h-18= - 18

h→0                             h→0

I need help can I don’t know how to do this problem
Elden [556K]

Answer:

a ^ (1/12)

Step-by-step explanation:

a ^ (1/3)

---------------

a ^ (1/4)

We know that b^ c / b^ d = b ^ (c-d)

a^ (1/3 - 1/4)

getting a common denominator

1/3 *4/4 - 1/4*3/3 = 4/12 - 3/12

a^ (4/12 - 3/12)

a ^ (1/12)

Describe how you know if an equation has INFINITE solutions. Give some examples of an equation that has infinite solutions,
MArishka [77]

Answer:

When a problem has infinite solutions, you'll end up with a statement that's true no matter what. For example: 3=3 This is true because we know 3 equals 3, and there's no variable in sight. Therefore we can conclude that the problem has infinite solutions. You can solve this as you would any other question.

Step-by-step explanation:

Hope this helped.
