A polynomlal has been factored, as SHOWI Deluw.

Tom [10]

Answer:

The zeros are 6,-5,9

Step-by-step explanation:

The factored form of the polynomial is given as:

$f(x) = (x - 6)(x + 5)(x - 9)$

To find the zeros of this function, we set f(x)=0 and solve for x.

$(x - 6)(x + 5)(x - 9) = 0$

This implies that:

$(x - 6) = 0 \: or \: (x + 5) = 0 \: or \: (x - 9) = 0$

We solve for x to get:

$x = 6 \: or \: x = - 5 \: or \: x = 9$

The zeros are 6,-5,9

Which situation represents a proportional relationship?

Natalka [10]

Answer:

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y=kx$

The ratio between the two variables is a constant called constant of proportionality k

$k=y/x$

<u><em>Verify each case</em></u>

A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

$\frac{4}{12}=\frac{9}{25}$

Multiply in cross

$4(25)=9(12)\\100\neq108$

Is not true

therefore

The situation not represent a proportional relationship

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

$\frac{5}{25}=\frac{8}{40}$

Multiply in cross

$5(40)=8(25)\\200=200$

Is true

therefore

The situation represent a proportional relationship

C) Larry packed 24 apples in 6 boxes and 46 apples in 9 boxes

$\frac{24}{6}=\frac{46}{9}$

Multiply in cross

$24(9)=46(6)\\216\neq276$

Is not true

therefore

The situation not represent a proportional relationship

D) Allie put 14 pieces of candy in 2 bags and 30 pieces of candy in 4 bags

$\frac{14}{2}=\frac{30}{4}$

Multiply in cross

$14(4)=30(2)\\56\neq60$

Is not true

therefore

The situation not represent a proportional relationship

Solve the equation 121x2+64=0

olganol [36]

Answer:

x = ± 8i/11

Step-by-step explanation:

121x2+64=0

121x^2 = -64

x^2 = -64/121

x = +/- √(-64/121)

x = +/- 8i/11

Nina saves 40% of her summer job earnings for college. This summer, she earned $200 more than last summer, and she saved $900. W

beks73 [17]

Answer:

(900 ÷ 4) x 10 -200 = 2050 And this will equal last Summer's earnings

Step-by-step explanation:

So we know that 900$ is equal to 40% and that we can simplify this

900 ÷ 4 = 225

40% ÷ 4 = 10%

Therefore:

225 = 10% and

2250 = 100% of earnings

What is the value of x^3\cdot y^1x 3 ⋅y 1 x, start superscript, 3, end superscript, dot, y, start superscript, 1, end su

satela [25.4K]

The expression $x^3y$ means that you have to cube the value of $x$ and multiply it by the value of $y$ .

So, the value of $x$ is 5, which becomes 125 when cubed. When we multiply it by the value of $y$ , which is 10, the result is 1250:

$x^3y = 5^3\cdot 10 = 125\cdot 10 = 1250$
