Answers

We are given the function:
[tex]h(t)=-16 t^{2} +4624[/tex]

In order to find out when will the sunglasses hit the​ ground we need to solve this function for t.
We start by moving t to the left side and everything ele to the right side:
[tex]16 t^{2} =4624[/tex]
Now we divide with 16:
[tex]t^{2} =289[/tex]
Now we take square root:
[tex] t_{1} = 17s \\ t_{2} = -17s[/tex]
We ignore negative solution as time can not have negative value.

It twill take 17s seconds for the sunglassesto hit the ground.

The property that justifies this statement is that of the Division Property of Equality. This property states that if you were to divide one side of an equation by a number, then you must divide the other side of the equation by the same number to ensure that the equation is still the same one that was started with. In the equation 3x=6, for example, to solve for x, one must divide both sides of the equation by three. By doing so, x is isolated, and we are able to find that x=2.

Find the Area of the figure

Answers

Hi there!

To solve this problem, we need to find the area of the circle and divide that by 2 to get the area of the semicircle, and then add that to the area of the rectangle.

First, let's find the area of the semicircle.

Since the area of a circle is calculated by pi × r^2 and diameter = 2r, we divide the diameter by 2 and plug it into the formula.

10 ÷ 2 = 5
pi × 5^2
= pi × 25
= 25pi
25pi ÷ 2 = 12.5pi

Now, let's find the area of the rectangle.
4 × 10 = 40

We add the areas together:

12.5pi + 40 = 79.27

So, the area is 79.27.

Hope this helps!

so that figure is basically made out of a rectangle + half of a circle

Area of a circle : pi × radius^2
r = 5 
area : 78.54
but we need half of it. so divide it by 2

39.27

area of the rectangle on the bottom : 10 × 4 = 40

40 + 39.27 = 79.27

so your answer is 79.27 in²

Arc length = 32.97 m .

Step-by-step explanation:

Given : In a circle with a radius of 6 m, an arc is intercepted by a central angle of 7π/4 radians and use 3.14 for π .

To find : What is the arc length.

Solution : We have given a circle of radius = 6 m

                                              Central angle  = 7π/4

A circular test track for cars has a circumference of 2.7km . A car travels around the track from the southernmost point to the northernmost point. What distance does the car travel? (answer 1.35km). Part B !!!!!!!What is the car's displacement from its original position?,

Answers

This problem is about the difference between distance and displacement.
The distance is how many kilometers has the car covered, the displacement is how far from the original point is the car now, and does not depend on the path followed, but it is the shortest path that connects two points.

a) In this part, they ask you for the distance. From the southernmost to the northernmost point of the circumference, the car has traveled half of the circumference, therefore:
distance = circumference ÷ 2 = 2.7km ÷ 2 = 1.35km

b) In this part, you are asked for the displacement, which in this case is the diameter of the circumference:
displacement = diameter = circumference ÷ π = 2.7km ÷ 3.14 = 0.86km = 860m

The set of life spans of an appliance is normally distributed with a mean mc013-1.jpg = 48 months and a standard deviation mc013-2.jpg = 8 months. What is the life span of an appliance that has a z-score of –3?

Answers

The life span would be 24 months.

The formula for z-scores is:
[tex]z=\frac{X-\mu}{\sigma}[/tex]

Using the information we're given we have:
[tex]-3=\frac{X-48}{8}[/tex]

Multiply both sides by 8 to cancel it:
-3(8) = ((X-48)/8)*8
-24 = X-48

Add 48 to both sides:
-24+48 = X-48+48
24=X

The life span of an appliance that has a z-score of –3 is 24 months if the set of life spans of an appliance is normally distributed with a mean is 48 months and a standard deviation is 8 months.

What is Z-test?

The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.

We have:

Z = -3,

[tex]\rm \mu = 48[/tex]

[tex]\sigma = 8[/tex]

We know the formula for the Z-score:

[tex]\rm Z = \frac{X-\mu}{\sigma}[/tex]

[tex]\rm-3= \frac{X-48}{8}[/tex]

-24 = X - 48

X = 24 months

Thus, the life span of an appliance that has a z-score of –3 is 24 months if the set of life spans of an appliance is normally distributed with a mean is 48 months and a standard deviation is 8 months.

Devin borrowed $1,058 at 13 percent for nine months. What will he pay in interest?
A. 103.16
B.105.80
C.137.54
D.122.40

Answers

A, 103.16 Hope this is right!

Devin borrowed $1,058 at 13 percent for nine months.

We have to calculate the interest paid.

Interest = [tex] \frac{P \times R \times T}{100} [/tex]

Substituting the values of

Principal = $1058

Rate = 13%

Time = 9 months = [tex] \frac{9}{12} [/tex] year

Interest = [tex] \frac{1058 \times 13 \times 9}{12 \times 100} [/tex]

Interest = 103.155

= 103.16

So, Devin will pay 103.16 as the interest.

Therefore, Option A is the correct answer.

A. An APR of 5.44% compounded semiannually
B. An APR of 5.42% compounded monthly
C. An APR of 5.34% compounded daily
D. An APR of 5.43% compounded quarterly

Answers

Charlie needs an effective rate of 950/900 -1 = 5.555%.

A) 1.0272^2 ⇒ 5.514% . . . . . . . . . . . . not enough

B) 1.0045166667^12 ⇒ 5.557% . . . . sufficient to reach the goal

C) 1.000146301^365 ⇒ 5.485% . . . . not enough

D) 1.013575^4 ⇒ 5.542% . . . . . . . . . .not enough

Charley needs an APR of 5.44% compounded semiannually to reach his goal of $950,000 in a year.(A)

Given:

Final Amount (A) = $950,000

Principal Amount (P) = $900,000

Time (t) = 1 year

We use the compound interest formula: A = [tex]P(1 + r/n)^{(nt)[/tex]

Option A: 5.44% APR compounded semiannually

APR (r) = 0.0544

Compounding periods per year (n) = 2

Plugging in the values, we get: A = 900,000[tex](1 + 0.0544/2)^{(2*1)[/tex]≈ $949,999 (which is approximately $950,000)

Option B: 5.42% APR compounded monthly

APR (r) = 0.0542

Compounding periods per year (n) = 12

Plugging in the values, we get: A = 900,000[tex](1 + 0.0542/12)^{(12*1)[/tex] ≈ $949,941 (less than $950,000)

Option C: 5.34% APR compounded daily

APR (r) = 0.0534

Compounding periods per year (n) = 365

Plugging in the values, we get: A = 900,000[tex](1 + 0.0534/365)^{(365*1)[/tex] ≈ $949,591 (less than $950,000)

Option D: 5.43% APR compounded quarterly

APR (r) = 0.0543

Compounding periods per year (n) = 4

Plugging in the values, we get: A = 900,000[tex](1 + 0.0543/4)^{(4*1)[/tex] ≈ $949,980 (missing the goal by a small amount)

Conclusion: The correct option is 5.44% compounded semiannually as it allows Charley to reach his goal of $950,000.

What is the area of the shaded region of the following figure?



446 in.2
5,760 in.2
4,788 in.2
5,274 in.2

Answers


[tex] {5274}in^{2} [/tex]

Explanation:
To find this answer you will have to follow these steps:

1) Convert all numbers to the same unotnof measurement (inches). So you would convert 8ft and 5ft into inches. (96in and 60in)

2) Now you have to find the area of the total figure (square). To find this you simply multiply length × width. (96in × 60in = 5760) Remember this for later.

3) Now you have to find the area of the triangle inside the shape. For this you multiply base × height then divide by 2. (36in × 27in = 927 then ÷ 2 to get 486.) 486 is the area of the triangle.

4) Finally to find the area of the shaded part of the shape you need to subtract the triangles area from the total area. (5760 - 486 = 5274 in)

Answer:

5,274 in.2

Step-by-step explanation:

Find the area of both the shaded and not shaded regions.

Shaded: 8 ft x 12 in = 96    5 ft x 12 in = 60

Then: 96 in x 60 in = 5760

Not Shaded: 27 in x (36 / 2) 18 in = 486

Then Subtract The Not Shaded Region From The Shaded Region:

5,760 - 486 = 5,274

Answers

That 10 is the diameter of the circle.
First let's find the area of the square.
A = s^2
Where 's' is the side.
A = 10^2
A = 100
Now let's find the area of the circle.
The '10' is also the diameter of the circle.
A = pi * r^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5
Now subtract this from the area of the square.
100 - 78.5 = 21.5
So the approximate area of the shaded region is 21.5cm^2

The correct answer would be D - 21.5 square centimeters.

A harris poll found that 35% of people said that they drink a caffeinated beverage to combat midday drowsiness. a recent survey found that 19 out of 48 randomly selected people stated that they drank a caffeinated beverage to combat midday drowsiness. at latex-8e4a9cff882bfbfe876f36fb5b4c08e8_5a945b8082ee7.png, is the claim of the percentage found in the harris poll believable?

Answers

Final answer:

To determine the believability of the Harris Poll's claim that 35% use caffeine to combat drowsiness, a hypothesis test for proportions is needed. The sample proportion of 39.58% from the recent survey would be tested against the null hypothesis of 35% using a z-score calculation. Depending on if the z-score falls within the critical region, we can either reject or fail to reject the null hypothesis.

Explanation:

To determine if the claim of the percentage found in the Harris Poll is believable based on the recent survey, we can conduct a hypothesis test for proportions. The null hypothesis (¿¿H₀) is that the true proportion of people who drink a caffeinated beverage to combat midday drowsiness is 35%, as stated by the Harris Poll. The alternative hypothesis (¿¿H₁) would be that the true proportion is different from 35%.

We use the information that 19 out of 48 randomly selected people stated that they drank a caffeinated beverage for midday drowsiness, which gives us a sample proportion of approximately 39.58%. To test this, we can calculate the z-score for the sample proportion and compare it to the critical value for α = 0.05 (two-tailed test). If the calculated z-score falls within the critical region, we reject the null hypothesis, indicating that the Harris Poll's claim is not believable. However, if the z-score is outside the critical region, we do not have enough evidence to reject the null hypothesis, and thus the claim is considered believable.

To perform this test, we would need to calculate the standard error for the proportion, z-score, and then compare the z-score to the appropriate critical value. Without performing the calculations here, we cannot definitively conclude about the believability of the Harris Poll's percentage claim. However, a statistician would run these numbers to reach a conclusion.
