The person was speeding at 93 miles per hour.

Step-by-step explanation:

Step 1: Given the equation to find speeding fine F = 7(s - 65) + 70
Step 2: Substitute given details in the equation and find s. F = $266

⇒ 266 = 7(s - 65) + 70

⇒ 266 = 7s - 455 + 70

⇒ 266 = 7s - 385

⇒ 651 = 7s

⇒ s = 651/7 = 93

The area of the base of the oblique pentagonal pyramid is 50 cm^2 and the distance from the apex to the center of the pentagon i

Verdich [7]

The complete question in the attached figure

Part a)
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6√2 cm
sin 45=AB/AC-----> AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm

the answer part a) is
AB=6 cm

Part b)
we know that
volume of the pyramid=(1/3)*Area of the base*height
area of the base=50 cm²
height=6 cm
so
volume of the pyramid=(1/3)*50*6----> 100 cm³

the answer part b) is
100 cm³

(w-w^2)^4=?<br>.......................

Setler [38]

Answer:

w^8 - 4w^7 + 6w^6 - 4w^5 + w^4 .

Step-by-step explanation:

(w - w^2)^4

= w^4 ( 1 - w)^4

By the binomial theorem:

= w^4( 1 - 4w + 6w^2 - 4w^3 + w^4)

= w^4 - 4w^5 + 6w^6 - 4w^7 + w^8

= w^8 - 4w^7 + 6w^6 - 4w^5 + w^4 ( Standard form).

Write an equation that is perpendicular to y = 2x + 5 and passes through (3 , -2)

Maslowich

To find the perpendicular line, we need to find the negative inverse slope.

y = -1/2x - 2

This line also passes through the point since both have the y intercept / value of -2.

Hope this helps!
