9. Find the length of a base of a triangle with<br>an Area of 100 and a height of 25.​
liraira [26]

Answer:

8 (units)

Step-by-step explanation:

The formula to find the area of a triangle is A = 1/2(b*h). Since we know the area already, we can substitute that value in to calculate the answer backwards.

Plug in the numbers known:

A = 100

h = 25

Equation: 100 = 1/2(b*25)

Now solve:

100 = 1/2(b*25)

200 = b * 25

<em>8 = b</em>

So, the answer to your question is 8 (units).

Hope this helps!

Write an algebraic rule to describe the translation c (5,-4) c'(-2,1)
Sauron [17]
We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)

James is participating in a 5-mile walk to raise money for a charity. he has received $200 in fixed pledges and raises $20 extra
Firlakuza [10]
The standard formula of a point-slope equation is (y-y1) = m(x-x1). So, we would arrange the final equation in this way as much as possible. Let y be the total amount her receives and x be the number of miles. That would be

y = 200 + 20x
y = 20 (10 + x)

That would be the equation. If he finishes the walk,

y = 20 (10+5)
y = $300

he would receive a total of $300.

Given the sequence -2,-8/3,-10/3,-4,-14/3 find the recursive formula
balu736 [363]

Step-by-step explanation:

-2, -8/3, -10/3, -4, -14/3

Write as multiples of 1/3.

-6/3, -8/3, -10/3, -12/3, -14/3

This is an arithmetic sequence where the first term is -6/3 and the common difference is -2/3.

Therefore, the recursive formula is:

aᵢ₊₁ = aᵢ − 2/3, a₁ = -2
