Find the surface area of the prism or pyramid. Round to the nearest hundredth if necessary.

son4ous [18]

Answer: 345.4

Step-by-step explanation:

SA=2πr^2+2πrh

SA=2(3.14)(5)^2+2(3.14)(5)(6)

SA=2(3.14)(25)+2(3.14)(30)

SA=2(78.5)+2(94.2)

SA=157+188.4

SA=345.4

Find an equation of a degree 3 polynomial (in factored form) with the given zeros of f(x): − 3 , 4 , − 3 . Assume the leading co

oksano4ka [1.4K]

f(x) = x³ + 2x² - 15x - 36 is the equation of a degree 3 polynomial (in factored form) with the given zeros of f(x) are − 3 , 4 , − 3 assuming that the leading coefficient is 1. This can be obtained by formula of polynomial function.

<h3>Find the required equation:</h3>

The zeroes or roots of a polynomial function are x values for which f(x) = 0

If the zeroes or roots are r₁, r₂, r₃,... then possible polynomial function is

⇒ f(x) = a(x - r₁)(x - r₂)(x - r₃)

where a is the leading coefficient

Here in the question it is given that,

Polynomial should be with degree 3
zeros of f(x) are − 3 , 4 , − 3

By using the formula of polynomial function we get,

⇒ f(x) = a(x - r₁)(x - r₂)(x - r₃)

⇒ f(x) = 1(x - (-3))(x - (4))(x - (-3))

⇒ f(x) = 1(x + 3)(x - 4)(x + 3)

⇒ f(x) = (x + 3)(x² - x - 12)

⇒ f(x) = x³ - x² - 12x + 3x² - 3x - 36

⇒ f(x) = x³ + 2x² - 15x - 36

Hence f(x) = x³ + 2x² - 15x - 36 is the equation of a degree 3 polynomial (in factored form) with the given zeros of f(x): − 3 , 4 , − 3 assuming that the leading coefficient is 1.

The denominator of a fraction is 5 more than twice the numerator. If both numerator and denominator are decreased by 7, the simp

Ugo [173]

Answer:

numerator is 10

denominator is 25

Step-by-step explanation:

let x be the numerator

let y be the denominator

write 2 equations:

y = 5 + 2x

$\frac{x-7}{y-7}$ = $\frac{1}{6}$

y is already isolated in the first equation, substitute into the second equation:

$\frac{x-7}{5+2x-7}$ = $\frac{1}{6}$

simplify:

$\frac{x-7}{2x-2}$ = $\frac{1}{6}$

cross multiply:

2x - 2 = 6(x - 7)

simplify:

2x - 2 = 6x - 42

subtract 2x:

-2 = 4x - 42

add 42:

4x = 40

divide by 4:

x = 10

plug in 10 for x in the first equation:

y = 5 + 2(10)

y = 5 + 20

y = 25

numerator is 10

denominator is 25
