a) 25 in2

b) 126 in2

c) 151 in2

d) 302 in2

Answer:

c 63.6

b 97

Step-by-step explanation:

Answer:

15.6 ft

Step-by-step explanation:

Let's call

From Pythagorean theorem:

c² = a² + b²

c = √(10² + 12²)

c = 15.6 ft

The length of the slide, which forms the hypotenuse of a right-angled triangle with the ground, is approximately 15.6 feet to the nearest tenth of a foot when calculated using the Pythagorean Theorem.

The question involves finding the length of a slide (hypotenuse) when its ladder and the ground form a right-angled triangle. The top of the ladder is 10 feet above the ground (opposite side), and the bottom of the ladder is 12 feet away from the bottom of the slide (adjacent side). We will use the Pythagorean Theorem to solve for the slide's length, which is represented by the equation a² + b² = c², where a and b are the lengths of the legs of the triangle and c is the length of the hypotenuse.

To evaluate f(3) for the given piecewise function, we use the second part of the function, which applies when x is between -4 and 3, inclusive. By substituting 3 into this piece, we find that f(3) is -11.

To find the value of f(3) for the given piecewise function, we need to determine which piece of the function applies when x is equal to 3. The function is defined as follows:
For x < -6, f(x) =
3x/2 + 8
For -4 ≤ x ≤ 3, f(x) = -3x - 2
For x > 3, f(x) = 4x + 4

Since 3 is within the range of the second piece (-4 ≤ x ≤ 3), we calculate the value by substituting x with 3 in the second function part:

f(3) = -3(3) - 2 = -9 - 2 = -11.
Therefore, the value that represents f(3) is -11.

Final answer:

To solve the equation 4 = 12x - 2, we need to find the value of x. The value that satisfies the equation is x = 1/2.

Explanation:

To find the value of x that makes the equation 4 = 12x - 2 true, we need to solve for x.

12x - 2 = 4

12x = 6

x = 6/12

x = 1/2

So, the value of x that satisfies the equation is x = 1/2.

Final answer:

When 941 is divided by 3, there are 313 groups of 3. To determine the number of groups of 100 that can be extracted, we divide 313 by 100, which results in 3 complete groups of 100 with 13 left over.

Explanation:

The question asks us to find out how many groups of 100 can be taken out of 941 when dividing by 3. First, we must divide 941 by 3 to understand this concept better:

941 ÷ 3 = 313 with a remainder of 2

Now, we know there are 313 groups of 3 in 941. However, the question asks for groups of 100. To find this, we can examine how many complete hundreds fit into the result of 313:

313 ÷ 100 = 3 with a remainder of 13

Therefore, 3 complete groups of 100 can be taken out when 941 is divided by 3, with 13 left over that cannot form another complete group of 100.

Approx. 28952.92

Step-by-step explanation:

Because cone volume is found by V=πr²[tex]\frac{h}{3}[/tex].

First you find the radius. Because you have the diameter, you divide that by two, because it's 48, and diameter is radius multiplied by 2. So the radius is 24. 24pi squared with height divided by three is volume so, 28952.92.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is 1/3πr²h.

The volume of the cone is 6028.8 inches³.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is 1/3πr²h.

We have,

Diameter = 48 inches

Radius = 24 inches

r = 24 inches

Slant height = 26 inches

L = 26 inches

L² = h² + r²

26² = h² + 24²

h² = 676 - 576

h² = 100

h = 10 inches

The volume of the cone.

= 1/3 x π x 24 x 24 x 10

= 3.14 x 8 x 24 x 10

= 6028.8 inches³

Thus,

The volume of the cone is 6028.8 inches³.

Answer:

B

Step-by-step explanation:

Currently, the graph looks like the attachment.

The centre of this circle is at (-4, -2), but when we flip it over the line x = 1 (the blue line on the picture), the centre will become ((1- -4) + 1, -2) = (6, -2).

Look for the equation [tex](x-h)^2+(y-k)^2=r^2[/tex] that matches this center. We want the center (h, k) to be (6, -2), so our equation should look something like:

[tex](x-6)^2+(y+2)^2=36[/tex]

The answer is B.

Answer:

(x - 6)² + (y + 2)² = 36

Step-by-step explanation:

Centre before reflection: (-4,-2)

Centre after reflection:

(-4+5+5,-2) = (6,-2)

(x - 6)² + (y + 2)² = 36

Given:

∠A = 66°

Whole circle is 360 degrees.

The railing is 120 degrees.

That is:

120/360 = 1/3 rd of the whole length of the circle (perimeter).

We will find perimeter of the circle (a.k.a. Circumference) and then multiply it by (1/3) to get meters of railing needed.

First, circumference:

[tex]C=2\pi r\\C=2 \pi (100)\\C=200\pi\\C=628.32[/tex]

The railing is (1/3)rd of it, so:

[tex]\frac{1}{3}*628.32=209.44[/tex]

The railing is 209.44 meters.

The answer choices are in pi, so it will be:

[tex]\frac{1}{3}*200\pi=\frac{200\pi}{3}[/tex]  meters

8³=512

Therefore 8 to the power of 3 is 512

Answer: 512

Step-by-step explanation: 8 to the power of 3 means the same as 8³.

The smaller 3 which is called the exponent tells us that we need to multiply the 8 three times. So we have 8 · 8 · 8 which simplifies to 512.

Step-by-step explanation:

The similarities between sine and cosine graphs are their amplitude and periodicity, while the differences are their starting positions and phase. Overall, the graphs are more similar than different.

Similarities:

The sine and cosine functions have the same amplitude, which is the maximum value of the wave.

Both functions are periodic, meaning they repeat their pattern infinitely.

Differences:

The sine function starts with an amplitude of zero, while the cosine function starts with an amplitude of one.

The sine and cosine functions are out of phase by 90 degrees, meaning they reach their maximum and minimum values at different times.

Overall, the graphs of the sine and cosine functions are more similar than different because they share the same amplitude and shape, but they differ in their starting positions and phase.
