Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds
Cerrena [4.2K]

Answer:

Area = 51.68yd^2

Step-by-step explanation:

Given

h = 9yd -- height

a = 2.5yd --- base sides

Required

Determine the surface area

The net is not given. So, I will solve directly.

The surface area is calculated as:

Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}

So, we have:

Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}

Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}

Area = 6.25 + 5\sqrt{1.5625 + 81}

Area = 6.25 + 5\sqrt{82.5625}

Area = 6.25 + 5* 9.086

Area = 51.68yd^2

Using the completing-the-square method, rewrite f(x) = x2 - 8x + 3 in vertex form.
Leto [7]

Answer:

B

Step-by-step explanation:

Given

f(x) = x² - 8x + 3

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 8x

x² + 2(- 4)x + 16 - 16 + 3

(x - 4)² - 13 ← in vertex form → B

Which is the radian measure of central angle KOL? StartFraction 3 pi Over 8 EndFraction radians StartFraction 3 pi Over 4 EndFra
bagirrra123 [75]

The above question is incomplete.

Complete Question

Minor arc KL measures 135°. Circle O is shown. Line segments K O and O L are radii. Which is the radian measure of central angle KOL?

a) StartFraction 3 pi Over 8 EndFraction radians

b) StartFraction 3 pi Over 4 EndFraction radians

c) StartFraction 7 pi Over 8 EndFraction radians

d) StartFraction 13 pi Over 5 EndFraction radians

Answer:

b) StartFraction 3 pi Over 4 EndFraction radians

Step-by-step explanation:

Minor arc KL measures 135°. Circle O is shown. Line segments K O and O L are radii.

Note that:

π radians = 180°

Therefore,

180° = π radians

135° = x

Cross Multiply

180° × x = 135° × π radians

x = 135° × π radians/180

x = 3π/4 radians

Therefore, the radian measure of central angle KOL is 3π/4 radians. Option b) is the correct option.
