Kara's Custom Tees will spend $540 to produce 8 shirts.

To determine the total expenses encountered by Kara's Custom Tees, we can use the equation:

C(x) = fixed costs + (variable costs per shirt) * x

In this case, the fixed costs are $500 and the variable costs per shirt are $5. Therefore, the equation becomes:

C(x) = 500 + 5x

To calculate the cost of producing 8 shirts, we substitute x = 8 into the equation:

C(8) = 500 + 5 * 8

= 500 + 40

= $540

Therefore, Kara's Custom Tees will spend $540 to produce 8 shirts.

The value of the function, h(0) is -4.

A function relates input and output. In other words, a function is a special relationship among the inputs (independent variable) and their outputs (dependent variable).

Therefore, let's solve the function.

Given the function h(x) = 5x - 4

Let's find the value of the function h(0). To find the value of the function h(0), we have to substitute the value of x as 0 in the function.

Therefore,h(0) = 5(0) - 4h(0) = 0 - 4h(0) = -4

Using the Pythagorean theorem and trig identities, it is proved sinθ + cosθ = 1.

The Pythagorean theorem states that for a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we can use the Pythagorean theorem to prove that sinθ+cosθ=1.

Let's take a right triangle with an angle θ and sides a, b and c, as shown in the diagram below:

By the Pythagorean theorem, we have:

a² + b² = c²

Now, we can substitute a and b with the trigonometric functions for the sides of our triangle:

sin²θ + cos²θ = 1

We can simplify this expression by using the trigonometric identity:

sin²θ + cos²θ = 1

sin²θ + cos²θ = (sinθ + cosθ)²

Substituting (sinθ + cosθ)² back into the equation, we get:

(sinθ + cosθ)² = 1

Hence, using the Pythagorean theorem and trig identities, it is proved sinθ + cosθ = 1.

The nearest tenth, the surface area of the given cylinder is approximately 175.9 cm².

To find the surface area (SA) of a cylinder, we need to calculate the sum of the lateral surface area (arl) and the base area (B).

The formula for the lateral surface area of a cylinder is given by:

arl = 2πrh,

where r is the radius and h is the height of the cylinder.

The formula for the base area of a cylinder is given by:

B = πr^2.

Let's calculate the values:

Given:

Height (h) = 5 cm

Radius (r) = 4 cm

First, we calculate the lateral surface area (arl):

arl = 2πrh

= 2 * 3.14159 * 4 cm * 5 cm

≈ 125.66368 cm²

Next, we calculate the base area (B):

B = πr^2

= 3.14159 * (4 cm)^2

≈ 50.26544 cm²

Finally, we find the surface area (SA):

SA = arl + B

≈ 125.66368 cm² + 50.26544 cm²

≈ 175.92912 cm²

Rounded to the nearest tenth, the surface area of the given cylinder is approximately 175.9 cm².

The Length of the ant to inches before we can compare the two lengths. We do this by dividing the numerator (3) by the denominator (32), which gives us a decimal of approximately 0.09375 inches.

To find how many times greater the length of the green anole lizard is compared to the crazy ant, we need to divide the length of the lizard by the length of the ant:

Length of lizard / Length of ant = 6 / (3/32) = 6 * (32/3) = 64

Therefore, the length of the green anole lizard is 64 times greater than the length of the crazy ant.

The correct answer is (D) 64.

It is important to pay attention to the units when working with ratios and proportions. In this case, the length of the lizard is given in inches, while the length of the ant is given in fractions of an inch. We need to convert the length of the ant to inches before we can compare the two lengths.

The diameter of the reservoir is:

Part (a): 112.86 m

part (b): 56. 44 m

The volume of a cylinder is given by the formula:

V = πr²h

where r is the radius and h is the height or depth

Part (a):

We have:

h = 10 cm = 0.1 m

V = 1000,000 litres = 1000 m³  (Remember: 1 litre = 1000 cubic metre)

V = πr²h

1000 = 3.14 * r² * 0.1

1000 = 0.314 r²

r² = 1000 / 0.314

r² = 3184.71

r = √3184.71

r = 56.43 m

Since diameter = 2 * r

diameter =  2 * 56.43

diameter = 112.86 m

part (b):

We have:

h = 10 cm = 0.1 m

V = 250,000 litres = 250 m³

V = πr²h

250 = 3.14 * r² * 0.1

250 = 0.314 r²

r² = 250 / 0.314

r² = 796.18

The given options, the only value greater than 1 is 1.003. Therefore 0.886, which is less than 1 and makes the inequality true.

The given number sentence is 5.3 × > 5.3, where we need to find the scaling factor that makes the inequality true. To do this, we can divide both sides of the inequality by 5.3. This gives us:

5.3 × x > 5.3 ÷ 5.3 × k

We need to find the value of k that makes the inequality true. Simplifying the right-hand side of the equation, we get:

5.3 ÷ 5.3 × k = k × 1 = k

Substituting this into our equation, we get:

5.3 × x > k

We know that 5.3 × 1 = 5.3, which means that k must be greater than 1 to satisfy the inequality. Among the given options, the only value greater than 1 is 1.003. However, this value would make the inequality too large, so it is not the correct answer.

The equation that can be used to find the nth term in the sequence, an, is: [tex]an = -4 \times 4^{(n-1)[/tex]

In a geometric sequence, each term is found by multiplying the previous term by a constant ratio.

Let's denote this ratio as "r."

Given that the first term, a₁, is -4, we can find the value of r by dividing the second term, a₂, by the first term, a₁.

a₁ = -4

a₂ = -16

r = a₂/a₁

Substituting the given values:

r = -16 / -4

r = 4

So, the common ratio, r, in this geometric sequence is 4.

To find the nth term, aₙ, in the sequence, we can use the formula:

It is a right triangle is the ratio of the length of one leg to the

length of the other leg = x/x =1/1. C.

In a 45-45-90 right triangle, the two acute angles are each 45 degrees, and the right angle is 90 degrees.

The special property of a 45-45-90 triangle is that its two legs are congruent, meaning they have the same length.

Let's denote the length of each leg as "x."

To determine the ratio of the length of one leg to the length of the other leg, we can compare the lengths.

Let's call the length of one leg "a" and the length of the other leg "b."

Since the two legs are congruent, we have a = b = x.

The ratio of the length of one leg to the length of the other leg is a:b = x:x.

Simplifying the ratio, we have a:b = 1:1.

This means that the length of one leg is equal to the length of the other leg in a 45-45-90 right triangle.

To recap:

Both legs have the same length, which is a property unique to this type of triangle.
