2⁴ × 2⁵ - (2²)²
= 2⁹ - 2⁴
= 512 - 16
= 496
Answer:
r equals start fraction cap a minus p over p t end fraction
Step-by-step explanation:
Subtract the term non containing r, then divide by the coefficient of r.
Answer:
Area=15in²
Perimeter=16in
Step-by-step explanation:
area=L×W
Perimeter=L+L+W+W
We are given original equation:
We need to find the enter and radius of a circle using the completing the square method.
The steps are as following :
Step 1 [original equation]: x^2 − 10x + y^2 + 12y = 20 .
Step 2 [group like terms]: (x^2 − 10x) + (y^2 + 12y) = 20
Step 3 [complete the quadratics]: (x^2 − 10x + 25) + (y^2 + 12y + 36) = 20 + (25 + 36).
Step 4 [simplify the equation]: (x^2 − 10x + 25) + (y^2 + 12y + 36) = 64.
Step 5 [factor each quadratic]: (x − 5)^2 + (y + 6)^2 = 8^2
Step 6 [identify the center and radius]: Center = (5, −6) Radius = 8.
<h3>Step 6 is incorrect.</h3><h3>The center should be (5,-6).</h3><h3> Replace − 5 with + 5 and replace + 6 with − 6.</h3>
Answer:
93 miles
Step-by-step explanation:
Use the distance formula:
d =
Plug in the values:
d =
d =
d =
d = 93.4
= 93 miles
