A rafter makes an angle of 28° with the horizontal. If the rafter is 15 feet long, what is the height at the rafter's peak? Draw a diagram.​

Answers

Answer 1

The height is 7.04 feet at the rafter's peak that makes an angle of 28° and 15 feet long.

What is angle?

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Length of rafter = 15 feet,

Angle made by rafter with the horizontal = 28°

Apply sin formula to determine the length x of the rafter,

sinθ = x / 15

sin28°  = x / 15

0.469 = x / 15

x = 7.04

The height of the rafter is 7.04.

What is dilation?

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

The scale factor is given as,

SF = 14 / 7

SF = 2

Then the value of the variable 'x' is calculated as,

x = 8 / SF

x = 8 / 2

x = 4 cm

The scale factor is 2. Then the value of the variable 'x' is 1 cm.

Adrian is going to invest $9,900 and leave it in an account for 10 years. Assuming the interest is compounded continuously, what interest rate, to the nearest hundredth of a percent, would be required in order for Adrian to end up with $17,700?

Answers

Answer:

did you ever get the answer bc I am struggling on this, pls help.

Step-by-step explanation:

Answer: 5.81%

Step-by-step explanation: Delta Math

A = 17700. P = 9900. t = 10

17700 = 9900e^r(10)

17700/9900 = 9900e^10r/9900

1.7878788 = e^10r

In(1.7878788) = In(e^10r)

In(1.7878788) = 10r

In(1.7878788)/10 = 10r/10

0.058103 = r

5.8103% = r

r = 5.81%

find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.

Answers

Answer:

13.5 cm

Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

L/θ = C/2π (C = Circumference = 2πr)

L/θ = 2πr/2π,

L/θ = r,

L = r*θ = 9 cm * 1.5 = 13.5 cm

Only hash channel catfish typically was about 0.06 g during the first six weeks of life at weight increase about 10% each day right a exponential model for the weight how much will the catfish gain weight after six weeks

Answers

Answer:

3.225 gram

Step-by-step explanation:

Given that :

Initial weight = 0.06g

Rate of increase, r = 10% = 0.1 per day

Weight gain after 6 weeks

For an exponential model. f(x)

f(x) = a(1 + r)^x

Where ; a = initial amount ; r = growth rate ; x = period

Our model becomes :

f(x) : 0.06(1 + 0.1)^x

f(x) = 0.06(1.1)^x

Number of days in 6 weeks = 6*7 = 42 = x

f(42) : 0.06(1.1)^42

= 3.285 gram

Hence, weight gain after 6 weeks :

(3.285 - 0.06) g = 3.225 gram

Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm

Answers

Answer:

Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible

Answer:

Yes, it does form a triangle

Step-by-step explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.
