Which of the following shows a graph of a tangent function in the form y = atan(bx − c) + d, such that b equals one fourth question mark

Given the word problem, we can deduce the following information:

1. Liz collected 16 cans, which is 20% of her goal.

To determine the number of cans that Liz needs to collect to reach her goal, we use below equation:

where:

x= total number of cans that Liz needs to collect

So,

Hence, the total number of cans is 80.

A.

To complete the double number line, we must determine first the other percent values. It the goal is 100%, we must subtract 20% from 100% and divide it by 4 to get the remaining percent values. So,

So the other percent values are:

0%

20%

20%+20%=40%

40%+20%=60%

60%+20%=80%

80%+20%=100%

To determine the amount of cans for each percent value,the process is shown below:

Therefore, the answer for double number line is:

Cans : 0 16 32 48 64 80

Percent : 0% 20% 40% 60% 80% 100%

B.

Based on the information gathered from A, for every 16 cans Liz collects, she adds 20% toward her goal. She will have 32 cans if she reaches 40% of her goal. Liz must collect 80 cans to reach her goal.

What are the minimum and maximum value of function?

Explanation:

To check maximum and minimum value of function.

First derivate the original function.

After putting first derivative equal to zero, critical points can be found.

Then, do second deritvative to check points of maxima and minima.

The critical points at which second derivative greater than zero. Point will be of minima.

The critical points at which second derivative less than zero. Point will be of maxima.

So,

Now, do second derivative test for maximum and minimum points

With each additional tree , the estimated time increases by 10 minutes .

in the question ,

a table with number of trees and time required to plant them is given .

For planting 1 tree 30 minutes is required to plant them .

for planting 2 trees 40 minutes is required to plant them .

increase in number of tree = 2 tree - 1 tree = 1 tree

change in time required = 40 min - 30 min = 10 min

for planting 3 trees , 50 minutes is required to plant them .

increase in number of tree = 3 trees - 2 trees = 1 tree

change in time required = 50 min - 40 min = 10 min

So, we can see that for every additional tree planted the time increases by 10 minutes .

Therefore , with each additional tree , the estimated time increases by 10 minutes .

The hypothesis for the test is:

H₀: ρ = 0 vs. H₀: ρ ≠ 0

The test statistic is:

r = 0.1983 ≈ 0.198

As the alternate hypothesis does not specifies the direction of the test, the test is two tailed.

The critical value for the two-tailed test is:

Considering the provided information. we are going to calculate the slope, and y-intercept of the line, so we obtain the following:

First we will calculate the slope using the following formula:

m=(y2-y1)/(x2-x1)

m=(80000-40000)/(10-5)

m=40000/5

m=8000

y-intercept:

y=mx+b

40000=(8000)5+b

40000=40000+b

b=0

Finally we obtain that the equation of the line is: y=8000x.

Let's graph the equation:

Answer: ∠ABD = 19°

Step-by-step explanation:

The angle formed by ABC is a complementary angle. This means the sum of both angles adds up to 90 degrees.

Since angle DBC is 71 degrees, 90 - 71 equals ∠ABD

90 - 71 = 19

Therefore ∠ABD = 19°

Answer:

m∠ABD = 19°

Step-by-step explanation:

Hello!

Recall that all angles of a rectangle are 90° in measure.

Angle B is 90°, and is made up of angles ABD and DBC.

We know the measure of angle DBC, it's given as 71°. We can find the measure of ABD by subtracting 71° from 90°.

So the measure of angle ABD is 19°.

To be able to determine the distance that the skier travels, let's first determine its constant rate (speed).

A skier travels for 4 seconds and covers 72 meters.

Constant Rate (Speed):

Determining the distance covered in 2 minutes:

Step 1: Convert the time in minutes into seconds.

Step 2: Multiply the time by the constant rate (speed) of the skier.

Therefore, in 2 minutes, the skier travels 2,160 meters.

Answer

x = 2, and y = 3

Explanation:

given the following linear equation

7x - 6y = -4------------- equation 1

14x + 5y = 43 ---------- equation 2

This equation can be solve simultaneously by using elimination method

Step 1 : eliminate x

To eliminate x, multiply equation 1 by 2 qnd equation 2 by 1

7x * 2 - 6y * 2 = -4 * 2

14x * 1 + 5y * 1 = 43 * 1

14x - 12y = -8 ----------------- equation 3

14x + 5y = 43------------------ equation 4

Substract equation 4 from3

(14x - 14x) - 12 - 5y = -8 - 43

0 - 17y = -51

-17y = -51

Divide both sides by -17

-17y/-17 = -51/-17

y = 51/17

y = 3

To find x, put the value of y into equation 1

7x - 6y = -4

7x - 6(3) = -4

7x - 18 = -4

Collect the like terms

7x = -4 + 18

7x = 14

Divide both sides by 7

7x/7 = 14/7

x = 2

Therefore, x = 2 and y = 3

The formula for the nth term is expressed as

an = (an - 1)^2 - 3

This is a recursive formula

This means that the second term, a2 is

a2 = (a2 - 1)^2 - 3

a2 = (a1)^2 - 3

a2 = 4^2 - 3 = 16 - 3 = 13

a3 = (a3 - 1)^2 - 3

a3 = (a2)^2 - 3

a3 = 13^2 - 3 = 169 - 3 = 166

a4 = (a4 - 1)^2 - 3

a4 = (a3)^2 - 3

a4 = 166^2 - 3 = 27556 - 3 = 27553

Answer

She burnt 181 calories in that first 10 minutes of the 5,000 meter race.

Explanation

Bella wrote the equation that relates her calories burnt (c) to number of minutes (m) she has run as

c = 18.1m

The question then asks us to find how much calories she burnt in the first 10 minutes of the 5,000 meter race.

That is, find c when m = 10 minutes

Recall,

c = 18.1m

c = 18.1 (10)

c = 181 calories.

The witch can make her special brew 6 times with the amount of water present in the small frog pond.

Given that:-

Total amount of water present in the small frog pond = 7 and 1/2 cups = 15/2 cups

Amount of water the witch needs to make her special brew = 1 and 1/4 cups = 5/4 cups

We have to find the number of times Wendy the witch can make her special brew with the amount of water present in the small frog pond.

We know that,

Number of times the witch can make the brew = Total amount of water/Water needed for brew

Hence, by simple division, we can write,

Number of times the witch can make the brew = (15/2) ÷ (5/4) = (15/2)*(4/5) = 6 times.
