Answer:

0 T, 4 D

1 T, 3 D

2T, 3D

3T, 2D

4T, 1D

5T, 1D

Step-by-step explanation:

So let's start with what we know!

Gift certificate = $100

T-shirts = $15 each

Dress shirts = $22 each

You need to buy at least one dress shirt in the process and at least spend $90

You can simply find the combinations by going in desmos and writing in:

15x + 22y <= 100

y > 1

15x + 22y >= 90

Find the combinations by looking at the integer values of x, and using only the integer values of y ( do not round them, just cut them down to the integer). Look where all the regions are shaded

The possible combinations are as follows

Note: I am going to initial t-shirts to T and dress shirts to D

0 T, 4 D

1 T, 3 D

2T, 3D

3T, 2D

4T, 1D

5T, 1D

Answer:

x = 23 and y = 15

Let one number be x and another be y

The sum of two numbers is 38

x + y = 38

x = 38 - y

The greater number is 8 more than the other number.

x - y = 8

x = 8 + y

solve both equations:

8 + y = 38 - y

y + y = 38 - 8

2y = 30

y = 15

solve for x:

x = 8 + y

x = 8 + 15

x = 23

Let one number be x and another be y

The sum of two numbers is 38

x + y = 38

x = 38 - y

The greater number is 8 more than the other number.

x - y = 8

x = 8 + y

solve both equations:

8 + y = 38 - y

y + y = 38 - 8

2y = 30

[tex]{{\bold{{{{{ \green{y = 15}}}}}}}}[/tex]

x ≥ 0

y ≥ (1/2)x

y ≤ 4 - x

Step-by-step explanation:

Dashed lines:  < and >

You need to create linear equations for the diagonal lines.

Shaded areas are ≥ if it is shaded above the line, and ≤ if shaded below the line.

Inequalities:

vertical line:   x ≥ 0

Answer:

A. (x,y)-(-x,y)

Step-by-step explanation:

1. Look at the first FG, It is Positive X and Positive Y

2. A reflection is simply flipping something to the opposite side, So now look at which part the 2nd FG is.

3. Now as we notice the G is in the Negative X, So that would be -X, But then when we look at the Y, It is in the positives!

Reciprocal of trigonometric ratios are also trigonometric ratios. The approximate value of csc(θ) for the corresponding given value of sin(θ) is given by: Option: C: 3.2362

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]

Thus, we see that [tex]\sin(\theta) = \dfrac{1}{\csc{\theta}}[/tex] for a specific angle θ, we get:

Actually, reciprocal of each trigonometric ratio will be a trigonometric ratio, for specific angle.

For the considered case, we're given that,

[tex]\sin(\theta) \approx 0.3090[/tex]

[tex]\sin(\theta) = \dfrac{1}{\csc(\theta)}\\\\\csc(\theta) = \dfrac{1}{\sin(\theta)} \approx\dfrac{1}{0.3090} \approx 3.2362[/tex]

Thus, the approximate value of csc(θ) for the corresponding given value of sin(θ) is given by: Option: C: 3.2362

The value of csc(θ) is 3.2362.

We have given that

sin(θ)=0. 3090

Now we have to find that what is the value of csc(θ)

What is the relation between cos(θ)and sin(θ)

csc(θ)=1/sin(θ)........(1)

Therefore by using (1)

csc(θ)=1/0. 3090........   use the value of sin(θ)

So simplify above we get,

csc(θ)=3.2362

Therefore we get

The value of csc(θ) is 3.2362.

The resulting solid will be a cylinder with a base radius of 14 cm and a height of 24cm. Then the correct option is D.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

The perimeter of the rectangle shown is 76 cm.

It is rotated about line b. A rectangle with a perimeter of 76 centimeters is shown.

The rectangle is rotated about line b at a side with a length of 24 centimeters.

Another side (x) of the rectangle will be

[tex]76 = 2 (24+x)[/tex]

then x is 14 cm

Then the resulting solid will be a cylinder of a base radius of 14 cm and height of 24cm. Then the correct option is D.
