PLEAS HELP ME ( :

Mathematics
1 answer:
jeyben [28]3 years ago
8 0

Answer:

C

Step-by-step explanation:

The kite is split into 4 triangles. Calculate the area of each triangle and add them together to find the area of the kite.

The top two triangles have the same measurements of height 6 inches and base 8.5 inches. Use the formula 1/2 b*h and double the area to find for both triangles.

A = 1/2 (8.5)(6)(2) = 51 square inches

The bottom two triangles have the same measurements as each other as well. There height is 13  and base is 8.5. Repeat the same processes.

A = 1/2 (8.5)(13)(2) = 110.5 square inches.

Now add together 51 + 110.5 = 161.6 square inches.

Write a polynomial function f of least degree that has a leading coefficient of 1 and the given zeros. Write the function in sta
NeX [460]

Answer:

f(x)=x^3+(3+\sqrt{5})x^2+(6\sqrt{5}-18)x

or

f(x)=x^3+3x^2+\sqrt{5}x^2-18x+6\sqrt{5}x

Step-by-step explanation:

A polynomial function with 3 zeroes is going to be of degree 3, so we're going to have at least least 3 factors of the form x-a, where <em>a </em>is a zero of the function. For three zeroes <em>a</em>, <em>b</em>, and <em>c</em>, we'd have the factors x-a,\ x-b, and x-c, making our function look like

f(x)=(x-a)(x-b)(x-c)

Substituting our roots for a, b, and c:

f(x)=(x-(-6))(x-0)(x-(3-\sqrt{5}))\\=(x+6)(x)(x-3+\sqrt{5})

To write this function in standard form, we can expand from left to right:

f(x)=(x^2+6x)(x-3+\sqrt{5})\\=(x^2+6x)x-(x^2+6x)3+(x^2+6x)\sqrt{5}\\=x^3+6x^2-3x^2-18x+\sqrt{5}x^2+6\sqrt{5}x\\=x^3+3x^2+\sqrt{5}x^2-18x+6\sqrt{5}x

At this point, we could either leave it as is, or group the coefficients for the x^2 and x terms to get

f(x)=x^3+(3+\sqrt{5})x^2+(6\sqrt{5}-18)x

I do not understand this question? Using partial quotients, which would be the best choice for the first number to subtract in t
marysya [2.9K]

Answer:

B. 520

Step-by-step explanation:

Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4

Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.

80 is the 20th multiple of 4 (80÷4 = 20).

Then subtract the number from the original number you want to divide

124 – 80 = 44

Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.

Subtract 40 from 44 you have 4 left.

It's now easy to divide 4 by 4 which is 1.

To now get the quotient in total, you'll add up

20 + 10 + 1 = 31.

Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.
