Can someone help with this?

Answer:

32

Step-by-step explanation:

Triangle angle = 180

First we add!

58 + 90 + c = 180

148 + c = 180

Now we subtract!

180 - 148 = c

32 = c

Answer:

x = 39

Step-by-step explanation:

Secant and tangent line from a point outside the cirlcle,

(length of th tangent)² = length of the secant * external segment

                   26²          =  (13 + x) * 13

               [tex]\sf (13 +x)*13 = 26 *26\\[/tex]

                           [tex]\sf 13 + x =\dfrac{26*26}{13}[/tex]

                           13 + x   = 2* 26

                           13  + x = 52

                                   x = 52 - 13

                                  x = 39

Answer:

64

Step-by-step explanation:
1. Plug it in:

(2(-4))^2

2 times -4 is -8

(-8)^2 = 64

So there’s your answer

The volume of the given pyramid comes to be 64 cubic inches.

Length of the square base a= 8 inches

Slant height l =5 inches

The volume of a pyramid is with base area A and height h is 1/3Ah.

So, base area A= 8*8 =64 square inches.

From Pythagoras theorem

[tex]l^{2} =(\frac{a}{2})^2 +h^{2}[/tex]

[tex]5^{2} =(\frac{8}{2})^2+h^{2}[/tex]

[tex]h=3[/tex] inches

So, volume of the pyramid = 1/3*A*h

=1/3*64*3

=64 cubic inches.

Hence, the volume of the given pyramid comes to be 64 cubic inches.

Answer:

45.2pi inches

Step-by-step explanation:

C=2×pi×r

since the answers already have pi we don't need to multiply it

C=2×22.6 = 45.2pi inches

Answer:

A. 22.6π

Step-by-step explanation:

Given:

22.6 inches across = diameter

What we need to find is how much ribbon do we need, so we use the formula:

C = 2πr

C = Circumference

r = radius = half diameter

Since we know the diameter, we do half of it to get the radius

22.6 ÷ 2 = 11.3

radius = 11

Now we substitute this into the formula:

C = 2πr

Substitute radius into formula

C = 2π(11.3)

Multiply 2 and 11.3

C = 22.6π

Answer:

13 through -infinity

or

13, -infinity

Step-by-step explanation:

A polynomial of degree 4 will have 4 zeros. The zero of 3 with a multiplicity of 2 counts as two of these zeros. You've also been given a zero of -i. So it seems that we only have 3 of the 4 zeros. We need all 4 to be able to form the desired polynomial.

You didn't mention that the polynomial should have real coefficients. But I'm going to assume it because otherwise we can't solve the problem. If a polynomial with real coefficients has a complex zero, then the complex conjugate of that complex zero will also be a zero. This is how we will find the 4th zero.

A complex number in standard form is a + bi. Its complex conjugate is a + (-bi) or a - bi. The complex zero we were given is -i. In standard form this would be 0 + (-i). The complex conjugate of 0 + (-i) would be 0 - (-i) or 0 + i or just i.

So the four zeros of the desired polynomial are 3 (twice), -i and i. If a number "z" is a zero of a polynomial then (x - z) is a factor of that polynomial. Using this fact and the four zeros we can write a factored form of our desired polynomial:

f%28x%29+=+a%28x-3%29%28x-3%29%28x-%28-i%29%29%28x-i%29

Simplifying the 3rd factor we get:

f%28x%29+=+a%28x-3%29%28x-3%29%28x%2Bi%29%28x-i%29

where the "a" is any non-zero number. Since there are an infinite number of non-zero numbers, there will be an infinite number of possible correct solutions to this problem. To make things easy we will choose to make "a" be 1. This makes our factored polynomial:

f%28x%29+=+%28x-3%29%28x-3%29%28x%2Bi%29%28x-i%29

All we have to do now is multiply this out. We can simplify this process if we take advantage of some factoring patterns. The first two factors can be multiplied using:

%28a-b%29%5E2+=+a%5E2-2ab%2Bb%5E2

And the last two factors can be multiplied using:

%28a%2Bb%29%28a-b%29+=+a%5E2-b%5E2

With these patterns we get:

f%28x%29+=+%28%28x%29%5E2-2%28x%29%283%29%2B%283%29%5E2%29%28%28x%29%5E2-%28i%29%5E2%29

Simplifying inside each factor we get:

f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2-i%5E2%29

And since i%5E2+=+-1 this becomes:

f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2-%28-1%29%29

or

f%28x%29+=+%28x%5E2-6x%2B9%29%28x%5E2%2B1%29

We have one more multiplication. There are no shortcuts for this one. We have to multiply each term of one factor times each term of the other and then add like terms, if any:

f%28x%29+=+x%5E2%2Ax%5E2%2Bx%5E2%2A1%2B%28-6x%29%2Ax%5E2%2B%28-6x%29%2A1%2B9%2Ax%5E2%2B9%2A1

Simplifying...

f%28x%29+=+x%5E4%2Bx%5E2%2B%28-6x%5E3%29%2B%28-6x%29%2B9x%5E2%2B9

f%28x%29+=+x%5E4%2B10x%5E2%2B%28-6x%5E3%29%2B%28-6x%29%2B9

Re-ordering into standard form:

f%28x%29+=+x%5E4%2B%28-6x%5E3%29%2B10x%5E2%2B%28-6x%29%2B9

This is a polynomial function of degree 4 with the given zeros.

P.S. As mentioned earlier, this is not the only possible correct answer. This is the answer when you make "a" equal to 1. Other values for "a" give us different polynomial functions which also have the same zeros. For example, if we had chosen a = 2 we would have gotten f%28x%29+=+2x%5E4%2B%28-12x%5E3%29%2B20x%5E2%2B%28-12x%29%2B18.

the question requires:

the time t required.

the equation of the inverse variation.

how do find t:

first we determine how much the tank holds by multiplying 120 by 40.

the tank holds 4800 gallons.

so now to find t we can use the formula v = d/t where d is the 4800 gallons.

so: t = d/v

t = 24 minutes

now for the equation of the inverse variation.

we can say that the equation is t = d/v since t and v are inversely proportional.

note that v and t stand for velocity and time respectively.

make sure to ask if you need any further guidance!!

The value of the function when x = 2 will be 9. The value is obtained by putting the value 2 in the place of x.

A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.

The given function in the problem is;

[tex]\rm f(x) = 2x^2 - 3x + 7[/tex]

On putting x =2 we get;

[tex]\rm f(2) = 2(2)^2 - 3(2) + 7 \\\\\ f(2) = 2(4) - 3(2) + 7 \\\\ f(2) = 8 - 6 + 7 \\\\ f(2) = 9[/tex]

Hence the value of the function when x = 2 will be 9.

Answer:

18.8

Step-by-step explanation:

First find the area of the rectangle, which is 4x3 (base x height) the area of the rectangle is 12.

We are given the radius as 2 for the quarter circles, and 2 quarter circles form 1 semicircle, so really we can solve for the area of one semi circle using the formula ( (pi*radius²)/2 ). Plug in the values and you should get 6.28.

Next, you add the area of the figures so 12+6.8 which is equal to 18.8.

Answer:

8 quarts

Step-by-step explanation:

1/3 of a gallon ---1/6 of a wall

                x  - 1 (all the wall)

                     x = (1 x 1/3) / 1/6

x = 1/3 / 1/6

                     x = 6/3

                     x = 2 gallons

1 gallons - 4 quarts

                     2 gallons -  x

  x = (2 x 4) / 1

                        x = 8 / 1

                        x = 8 quarts
