A triangle has a base of 13 inches and an area of 82.5 inches. What is the height of the triangle?

Answers

Answer:

Height - 12.692 in

Step-by-step explanation:

Answer:

A = 1/2 bh

Step-by-step explanation:

Replace are and base to get:

82.5 = 1/2 x 15 x height

Multiply both sides by 2:

165 = 15 x height

Divide both sides by 15:

Height = 165 / 15

Height = 11 inches.

Answer:

Step-by-step explanation:

2(x+7)^2 =98  

(x+7)^2 = 49  (divide both sides by 2)

(x +7) = [tex]\sqrt{49}[/tex]  (square root both sides)

x + 7 = 7  ( we are not sure if this is  -7 or  +7, because either would work )

so we have two solutions now

x +7 = -7     or      x +7 = 7

x = -7 -7      or      x =7 -7    (subtract 7 from both sides)

x = - 14        or      x = 0

Multiply the complex numbers: (3 + 2i)(5 – 2i)

Answers

Answer:

19+4i

Step-by-step explanation:

Multiply using the FOIL method, then combine the real and imaginary parts of the expression.

FOIL

A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.

Result of multiplication of complex numbers will be 19 + 4i

Given,

(3 + 2i)(5 – 2i)

Here,

Complex numbers standard form : x ± iy

Here,

x = real part

y = complex part.

i = iota = [tex]\sqrt{-1}[/tex]

So,

Multiplication :  (3 + 2i)(5 – 2i)

⇒15 -6i + 10i -4i²

Here,

i = √-1

i² = -1

So,

15 -6i + 10i -4i²

15 -6i + 10i - 4(-1)

⇒19 + 4i

Instructions: Find the measure of the indicated angle.

Answers

Answer:

x = 66

Step-by-step explanation:

the triangle has 2 congruent sides and is therefore isosceles with the 2 base angles being congruent, then

x = 66

The measure of the indicated angle is 66 degree.

What is Isosceles Triangle ?

An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:

It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.

We have a Triangle.

Then, using Isosceles Triangle Theorem

Angles opposite an isosceles triangle's equal sides are also equal.

According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.

So, x= 66 degree.

A town has a population of 72,700 and grows at a rate of 3.5% every year. Which equation represents the town’s population after 4 years?

For n years: [tex]72,700 + 1.035^n(72,700)[/tex]

Step-by-step explanation:

Since each year the growth rate is 3.5 of the last year, n will represent the number of years.

[tex]72,700 + 1.035^n(72,700)[/tex]

Therefore since n is 4, the equation will be:

[tex]72,700 + 1.035^4(72,700) =72,700 + 1.15(72,700)[/tex]

Step-by-step explanation:

Formula for volume -> V = 4/3 πr³

We know the circumverence now we need to et the radius.

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

Divide the diameter by 2.

The profit which the manufacturer gained from the warranties is a. $105,430,050

Calculations and Parameters:

Given that count 12% of 532,475:

532,475 - 100%

x - 12%

x= 63, 897.

This means that 63, 897 guitars were sold with a full-replacement warranty and 532,475-63,897=468,578 electric guitars were sold without a full-replacement warranty.

A Ferris wheel has a radius of 80 feet. Two particular cars are located such that the central angle between them is 165º. To the nearest tenth, what is the length of the intercepted arc between those two cars on the Ferris wheel?

Answers

Answer: 230.4 feet

Step-by-step explanation:

arc length = circumfrance x fraction of a circle

                 = [tex]2\pi r[/tex] x [tex]\frac{165}{360}[/tex]

                 = [tex]\frac{2*\pi *80*165 }{360}[/tex]

                 = 230.4 feet to nearest tenth

The length of the intercepted arc between those two cars on the Ferris wheel is 230.4 feet. This is obtained by using the arc length formula in degrees.

Arc length:

The distance across the curved length is said to be arc length.

The arc length is calculated by using the formula:

arc length = circumference × fraction of circle

⇒ arc length = 2πr × θ/360° when θ is given in degrees

where r is the radius.

Given data:

Given that,

A Ferris wheel has a radius of r=80 feet

Two particular cars are located such that the central angle between them is 165° i.e., θ = 165°

Calculating the length of the arc:

arc length = 2πr × θ/360°

⇒ 2π×80×[tex]\frac{165}{360}[/tex]

⇒ 230.38 feet

Rounding off to the nearest tenth, we get arc length = 230.4 feet.

Step-by-step explanation:

Deviations:

98 - 89.1 = 8.9

92 - 89.1 = 2.9

90 - 89.1 = 0.9

78 - 89.1 = -11.1 = 11.1  (absolute value)

83 - 89.1 =  6.1

88-89.1 = 1.1

95 - 89.1 = 5.9

So the MAD
