3 to the power of 5 i think
Solve by using the formula: c² - b² = a²
c = hypotenuse, b = leg, a = a
Plug in:
(√73)² - (8)² = a²
Simplify.
73 - 64 = a²
9 = a²
Isolate the a. Root both sides
√a² = √9
a = √9
a = √9 = √(3 * 3)
a = 3
3 ft is your answer
hope this helps
Is that 3x (2) or 3 multiplyed by 2 ?
is it is 2 times 3 the answer is
11+2y-4z
Answer:
y = 0.7(x^2 - 64x - 576)
Average rate of change = -49.
Step-by-step explanation:
As the x intercepts are -8 and 72 we can write the equation
y = a(x + 8)(x - 72) where a is some constant to be found.
As it passes through point (62, -490) we have, substituting:
-490 = a(62+8)(62-72)
-490 = - 700a
a = 0.7
So the equation of the parabola
y = 0.7(x + 8)(x - 72) or
y = 0.7(x^2 - 64x - 576).
Average rate of change between x = -8 and x = 2
= [0.7(2+ 8)(2 - 72) - 0.7(-8+8)(-8-72)] / (2 - -8)
= -490 - 0 /10
= -49
Answer:
Opposite angles of a cyclic quadrilateral add to 180°
Angel CBA and angle ADC adds up to 180°.
CBA + ADC = 180
CBA = 180 - ADC
x + CBA = 180
x + 180 - ADC = 180
x - ADC = 0
x = ADC
y + ADC = 180
y + x = 180
