Answer:
The Area of Δ ABC = 219.13
Step-by-step explanation:
<em>The hard part about this problem is finding the area without the height</em>
The formula to do this is Area =
A, B, C represent the sides
S represents (A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
<u>Sides B and C are the same length</u> because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
<u>Remember:</u> S represents (A + B + C)
S = (28 + 21 + 21)
S = (70)
S = 35
<em>Lets plug the numbers into the Area Formula now!</em>
Area =
According to the order of operations, we need to do the calculations in parentheses <u>first</u>
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
= 219.13
The Area of Δ ABC = 219.13
Answer:
y = 4
Step-by-step explanation:
For an exponential function in standard form
y = a
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a (
= 1 ), so
a = 4
y = 4
Using (1, 8 ), then
8 = 4 = 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 ← exponential function
Answer:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is ⇒ C
Step-by-step explanation:
The formula of the slope of a line passes through points and
is
∵ The line passes through points (5 , 0) and (6 , -6)
∴ = 5 and
= 6
∴ = 0 and
= -6
Substitute these values in the formula of the slope
∵
∴
Let us look to the answer and find the same formula
The answer is:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is
