We know that,
diameter is twice the radius, I.e d = 2r
Now d = 2(8)ft = 16 feet
Answer:
4cm or 7 cm
Step-by-step explanation:
it can make 2 sides equal and make a isosceles triangle
When we prime factorize, we get 180=2^2*3^2*5. So therefore there are 3 prime factors that make up 180.
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
y = 2x² + 12x + 1
To express in vertex form use the method of completing the square.
The coefficient of the x² term must be 1 , thus factor out 2 from 2x² + 12x
y = 2(x² + 6x) + 1
add/ subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9) + 1
= 2(x + 3)² - 18 + 1
= 2(x + 3)² - 17 → C
