ANSWER

5 pairs

EXPLANATION

We have that:

- one pair of pants cost $24.95

- one t-shirt costs $22.50

- one pair of socks cost $5.95

You want to buy one pair of pants, one t-shirt and several pairs of socks and you don't want to spend more than $80.

This means that everything you spend must be less than or equal to $80.

Let the number of pairs of socks you can buy be x.

This therefore means that:

Because we know that the number of pairs of socks must be a whole number, we have to approximiate to whole number, which will be:

x = 5

Therefore, you can buy at most 5 pairs of socks.

We need to find the equation of the new function g(x) obtained by vertically stretching the function:

Vertically stretching a function by a factor of k corresponds to multiplying the whole expression of function by k:

In this problem, we have k = 18. Thus, we obtain:

Answer: C. g(x) = 18x²

Given the functions:

By definition, (f+g)(x) is equivalent to:

Finally, using the expressions for f and g:

-2/5t - 6 + 2/3t + 15​

Combining similar terms

(-2/5t + 2/3t) + (-6 + 15)

4/15t + 9

Answer:

C

Explanation:

Given:

Volume of a cylinder (V) = 4pi cubic units

To find:

Base area(A) and height(h)

Recall that the volume of a cylinder(A) is usually given as;

So let's go ahead and try each of the options and see which gives us 4pi on the left-hand side as we have on the right-hand side for Volume.

For option A;

We have that A = 1 and h = 2, so we'll have;

For option B;

We have A = 2pi and h = 1, so we'll have;

For option C;

We have A = 2pi and h = 2, so we'll have;

We can see from the above that option C is the right option.

substitute in the formula above

therefore

the answer is

The value of the car after 5 years is $13,500 and the value of the car after 9 years is $10,500.

According to the question,

We have the following information:

The value of the car is given by V(x) where x is the number of years.

V(x) = -1500x + 21,000

(a) Now, to find the value of car after 5 years, we will put 5 in place of x in the given expression:

V(5) = -1500*5+21000

V(5) = -7500+21000

V(5) = $13,500

(b) Now, to find the value of car after 9 years, we will put 9 in place of x in the given expression:

V(9) = -1500*9+21000

V(9) = -10500+21000

V(9) = $10,500

(c) When V(12) = 3000 then it means that the value of the car after 12 years is $3000.

Hence, the value of car after 5 years and 9 years is $13,500 and $10,500 respectively.

1) Using the data from the table, we plot the following segmented bard chart for the relationship between age and behaviour toward humans.

2) From the graph we see that for each behaviour towards humans, we have approximately the same percentage of juveniles (around 10%) and adults (around 90%), that's because the blue and green portions are proportionally the same for each bar. Based on what we see from the graph, we conclude that there is no association between age and behaviour towards humans.

We're going to use length DC and ML, along with DA and MJ

[tex]\frac{DC}{ML} = \frac{5}{6}[/tex] which is 0.833333333

now for

[tex]\frac{DA}{MJ} =\frac{7}{8.4}[/tex] which is 0.833333333 (again)

as you can see since the shapes ABCD and JKLM are similar, they have a relationship which in this case is 0.833333333

and we can use this 0.833333333 to help us find the length of KL

knowing that any length for ABCD divided by JKLM is 0.833333333

we can do

[tex]\frac{CB}{LK}=0.833333333[/tex]

since we don't know what KL is, we can switch the spots and enlongate it, to become:

500 - 2x = quarters

the total value of the coins is $72.50

5x + 10x + 25(500-2x) = 7250

Solve for x

15x + 25(500) + 25(-2x) = 7250

15x + 12,500 - 50x = 7250

Combine like terms

15x - 50x = 7250 - 12500

-35x = -5250

Divide both sides of the equation by -35

-35x/-35 = -5250/-35

x = 150

Explanation:

The formula for calulating mean deviation is expressed as:

where;

m is the mean of the data set

Xi are individual values

n is the total sample space

Get the mean;

n = 7

mean = (10+12+11+15+9+8+5)/7

mean = 70/7

mean = 10

Get the mean deviation:

Mean deviation = (10-10)+(12-10)+(11-10)+(15-10)+(9-10)+(8-10)+(5-10)/7

Since the values is in modulus |xi - m| will give a positive value, hence;

Mean deviation = (0+2+1+5+1+2+5)/7

Mean deviation = 16/7

Mean deviation = 2.28

Mean deviation = 2.3 (to the nearest tenth)

Hence the value of x is 8.

[tex]4x + 3x = 56\\7x = 56\\x = 56/7\\x = 8[/tex]

The answer is X=8

Step-by-step explanation:

9)

it is not linear, because while x is increasing with every data point by 1, y is decreasing and increasing again, and the differences from one point to the other vary.

for a linear relationship also y has to change in a constant way, and the difference from one point to the next would be the same for all points.

10)

so, since it is not linear, it is quadratic then (since that was our only given alternative).

y = ax² + bx + c

we know c from point (0, -6). c = -6.

for a and b we need to use 2 data points with their x and y coordinates.

let's start with the first (-2, 14)

14 = a×(-2)² + b×-2 - 6 = 4a - 2b - 6

we can simplify that

7 = 2a - b - 3

and then

10 = 2a - b

the next point is (-1, -1)

-1 = a×(-1)² + b×-1 - 6 = a - b - 6

5 = a - b

so, we have the 2 equations

10 = 2a - b

5 = a - b

from the second we get

a = 5 + b

and that we can use in the first equation

10 = 2×(5 + b) - b = 10 + 2b - b

0 = b

therefore

5 = a - b = a - 0 = a

a = 5

and the equation is

y = 5x² - 6

f(-7) = 5×(-7)² - 6 = 5×49 - 6 = 245 - 6 = 239

(a standard deck card has 52 cards)

Now, let's calculate the number of hands that have 4 aces. Since the fifth card can be any of the remaining 48 cards after picking the 4 aces, there are 48 possible hands that have 4 aces.

Then, the probability of having a hand with 4 aces is given by the division of these 48 possible hands over the total number of possible hands of 5 cards:

The probability is 1/54145.

Answer:

Yes.  r = 3 + 3sin θ is symmetrical along the y axis

Step-by-step explanation:

Original polar equation is

r = 3 + 3sinθ

If this plot is to be symmetrical about the y axis then replacing Θ with (π-θ) in the original equation should not change the equation and thereby should not change the plot

r = 3 + 3sinθ

Replace θ with π-θ:

==>  3 + 3sin(π-θ)

But sin(π-θ) = sinθ

So the equation is unchanged at 3 + 3sin(π-θ) from the original equation r = 3 + 3sinθ

Hence the equation is symmetrical along the y-axis

This can be also be clearly seen if you plot both the equations, you will see the plot does not change

Answer:

15

Step-by-step explanation:

5x + 9 and 84 are alternate interior angles.

Since,

lines l and m are parallel, alternate interior angles are equal.

So,

5x + 9 = 84

Step 1 : Subtract 9 on both sides.

5x = 84 - 9

5x = 75

Step 2 : Divide 5 on both sides.

x = 75/5

x = 15

Hence,

The value of x is 15.

We will solve as follows:
