Sam volunteers at an animal shelter. He created a line plot to show the weights in pounds of the kittens at the
shelter
Weights of Kittens in Shelter

Pounds
What is the total weight of the kittens in the shelter? Enter your answer in the box
pounds

Answers

Answer:

5 pounds

Step-by-step explanation:

The line plot shows that we have 3 kittens with 1/2 pounds, 2 kittens with 1 pound and 1 kitten with 1 1/2 pound.

So, to find the total weight of the kittens in the shelter, we can multiply the number of kittens by their weights, and then sum then all:

Total weight = 3 * (1/2) + 2 * 1 + 1 * (1 + 1/2)

Total weight = 3/2 + 2 + 3/2 = (3 + 4 + 3)/2 = 10/2 = 5 pounds

A catapult launches a boulder with an upward velocity of 120 ft/s. The height of the boulder, h,

hundredth, if necessary.
a. Reaches a maximum height of 235.00 feet in 3.75 seconds.
b. Reaches a maximum height of 10.00 feet in 7.50 seconds.
c. Reaches a maximum height of 7.58 feet in 3.75 seconds.
d. Reaches a maximum height of 15.16 feet in 7.5 seconds.

Answers

Answer:

Reaches a maximum height of 235.00 feet in 3.75 seconds.

Step-by-step explanation:

The height of the boulder, h,  in feet after t seconds is given by the function is given by :

[tex]h=-16t^2+120t+10[/tex] .....(1)

For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

i.e.

[tex]\dfrac{d(-16t^2+120t+10)}{dt}=0\\\\-32t+120=0\\\\32t=120\\\\t=3.75\ s[/tex]

Put t = 3.75 in equation (1). So,

[tex]h=-16(3.75)^2+120(3.75)+10\\\\h=235\ \text{feet}[/tex]

So, the boulder's maximum height is 235 feets and it takes 3.75 s to reach to its maximum height.

Brian invests £1300 into his bank account.

He receives 10% per year simple interest.

How much will Brian have after 3 years?

Give your answer to the nearest penny where appropriate.

Answers

Answer:

£1690

Step-by-step explanation:

Amount invested by Brian = £1300

rate of simple interest = 10%

To find money Brian will have after three years

He will have amount invested in bank and interest earned in three years from that amount.

Simple interest for any principal amount p is given by

SI = P*R * T /100

where SI  is simple interest earned

T is time period for which simple interest is earned

R is rate of interest

Substituting value of P , R and T we have

SI = 1300*10* 3 /100 = 390

Therefor interest earned will be £390

Total money with Brian after three years = principal amount invested + interest earned in 3 years

= £1300 + £390 = £1690

Show how to find the inverse of f(x) = x^3 - 5. Calculate 3 points on f(x) and use these points to show that the inverse is correct.

Answers

Answer:

[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]

Step-by-step explanation:

A function [tex]f^{-1}[/tex] is the inverse of f if whenever y =f(x) and [tex]x =f^{-1}[/tex]

To find the  inverse of f(x) = [tex]x^{3}[/tex] - 5, we use the following steps:

Step 1 : Put y for f(x) and solve for x

y = [tex]x^{3}[/tex] - 5

<=> [tex]x^{3}[/tex]  = y + 5

<=> x = [tex]\sqrt[3]{y+ 5}[/tex]

Step 2: Put [tex]f^{-1}(y)[/tex] for x, we have:

[tex]f^{-1}(y) =\sqrt[3]{y+5}[/tex]

Step 3: Interchange y =x, we have

[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]

Let Calculate 3 points on f(x)

x = 0 => y = -5

x = 1  => y = -4

x = 2 => y = 3

Let Calculate 3 points on [tex]f^{-1}[/tex] (x)

x = -5 => y = 0

x = -4  => y = 1

x = 3 => y = 2

The head-to-tail length of a species of fish is normally distributed, with a

mean of 17.4 cm and a standard deviation of 3.2 cm. One fish is 16.3 cm

long. What is the score of the length of this fish? Round your answer to two

decimal places.

A. 0.54

B. 0.34

C. -0.34

D. -0.54

Answers

Answer:

C. -0.34

Step-by-step explanation:

We have that for a normal distribution, the value of z can be calculated using the following formula:

z = (x - m) / sd

where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 16.3, m = 17.4 and sd = 3.2

if we replace we have:

z = (16.3 - 17.4) /3.2

z = -0.3437

if we round to 2 decimal places, it would be -0.34, that is, the answer is C.

The z-score for a fish measuring 16.3 cm, with a mean length of 17.4 cm and a standard deviation of 3.2 cm, is -0.34.

The score of the length of the fish, also known as the z-score, is calculated by subtracting the mean from the observed value and then dividing by the standard deviation. Using the provided data, we have a mean (μ) of 17.4 cm and a standard deviation (σ) of 3.2 cm. The fish in question measures 16.3 cm.

To find the z-score, the calculation is as follows:

Z = (X - μ) / σ

Z = (16.3 cm - 17.4 cm) / 3.2 cm

Z = -1.1 cm / 3.2 cm

Z = -0.34 (rounded to two decimal places)

Therefore, the z-score for a fish that is 16.3 cm long is -0.34, which corresponds with answer option C.

a concrete pillar has the shape of a cylinder. it has a diameter of 6 meters and a height of 7 meters. concrete cost $116 per cubic meter how much did the concrete cost for the pillar

Answers

Answer:

The cost of the pillar is $22,947.12

Step-by-step explanation:

Diameter of the pillar = 6m

Radius = diameter / 2 = 6 / 2 = 3m

Height if the pillar = 7m

Volume of the pillar = πr²h

π = 3.14

V = 3.14 × 3² × 7

V = 3.14 × 9 × 7

V = 197.82m³

Volume of the pillar is 197.82m³

If 1m³ = $116

197.82m³ will cost $x

X = (197.82 × 116) / 1

X = $22,947.12

The cost of the pillar is $22,947.12

What is Parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.

We have the parabolic equation: y= ax²

1. If 'a' is positive, the parabola will open to the right or upwards.

2. If "a" is negative, the parabola opens to the left or downward.

3. The parabola expands either upwards or downwards if x is squared.

4. The parabola opens to the left or right if y is squared.

Now, as we are given the parabola having x² and 'a' is negative.

Thus, from the points 4 and 2, we get,

A game room has a floor that is 120 feet by 75 feet. A scale drawing of the floor on grid paper uses a scale of 1 cm: 5 feet.

What are the dimensions of the scale drawing?

Answers

Answer:

24cm x 15cm

Step-by-step explanation:

120/5 = 24 cm

as 24 cm x 5 = 120 feet.

We check 75 feet

75/5 = 15 cm

as 15 cm x 5 = 75 feet

So the answer is 24cm x 15cm

A photo is printed on a 20-inch by 24-inch piece of paper. The photo covers 320 square inches and has a ubiform border. What is the width of
the border?

Answers

Answer:2 in.

Step-by-step explanation:

Given

Dimension of photo frame is [tex]20\ in.\times 24\ in.[/tex]

If the photo cover an area of [tex]320\ in.^2[/tex]

Suppose x be the width of border

Therefore dimension of frame without border is

[tex]A'=(20-2x)(24-2x)[/tex]

And [tex]A'[/tex] must be equal to [tex]320\ in.^2[/tex]

So,

[tex]\Rightarrow (20-2x)(24-2x)=320[/tex]

[tex]\Rightarrow (10-x)(12-x)=80[/tex]

[tex]\Rightarrow 120-10x-12x+x^2=80[/tex]

[tex]\Rightarrow x^2-22x+40=0[/tex]

[tex]\Rightarrow x^2-20x-2x+40=0[/tex]

[tex]\Rightarrow (x-2)(x-20)=0[/tex]

Thus there are two values of x out of which [tex]x=20\ in.[/tex] is not valid because it is not feasible

thus width of border is [tex]x=2\ in.[/tex]

Which of the following shows extraneous solutions to the logarithmic equation? (See picture)

Answers

Answer:

Option 3

Step-by-step explanation:

log4(x) + log4(x - 3) = log4(-7x + 21)

log4(x² - 3x) = log4(-7x + 21)

x² - 3x = -7x + 21

x² + 4x - 21 = 0

x² + 7x - 3x - 21 = 0

x(x + 7) - 3(x + 7) =0

(x + 7)(x - 3) = 0

x = -7, 3

-7 and 3, both are e extraneous solutions because logs of non-positive numbers don't exist

the radius of a circle is 5 inches what is the area of a sector biunded by 180 degrees arc

Answers

Final answer:

The area of a sector with a radius of 5 inches and a 180-degree arc is half the area of the full circle, resulting in 39.27 square inches when rounded.

Explanation:

The area of a sector of a circle with radius 5 inches that is bounded by a 180-degree arc can be found by first calculating the area of the entire circle and then taking half of that area, since 180 degrees is half of the full 360 degrees of a circle. The formula to calculate the area of a circle is A = πr². For a radius (r) of 5 inches, the entire circle's area would be A = π(5 inches)².

Thus, the entire circle area is A = 3.1415927 × (5 inches)² = 78.53981633974483 square inches. Since the sector is half of the circle, the area of the sector would be 39.269908169872415 square inches, or when rounded to two decimal places, 39.27 square inches.
