melamori03 [73]

Answer:

Step-by-step explanation:

$i^{12}= i^{2} *i^{2} *i^{2} *i^{2} *i^{2} *i^{2}$

Remember that $i^{2}=-1$

Plug it in:

$i^{12}= (-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2}$

$=1*1*1*1*1*1$

$=1$

A rocket is launched from atop a 55-foot cliff with an initial velocity of 138 ft/s. a. Substitute the values into the vertical

Nonamiya [84]

It would take 9 seconds.

Substituting the values into the equation, we have:

0 = -16t² + 138t + 55

The quadratic formula is:
$t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Inserting our information we have:
$t=\frac{-138\pm \sqrt{138^2-4(-16)(55)}}{2(-16)}
\\
\\=\frac{-138\pm \sqrt{19044--3520}}{-32}
\\
\\=\frac{-138\pm \sqrt{19044+3520}}{-32}
\\
\\=\frac{-138\pm \sqrt{22564}}{-32}
\\
\\=\frac{-138\pm 150}{-32}=\frac{-138+150}{-32}\text{ or } \frac{-138-150}{-32}
\\
\\=\frac{12}{-32}\text { or } \frac{288}{32}=-0.375 \text{ or } 9$

Find all of the zeros of the function f(x) = x^3 + 5x^2 + 6x. If there is more than one answer, enter your answers as a comma se

suter [353]

<h2>Answer:</h2>

There are more than one zero i.e. three zeros of the given polynomial.

The zeros are:

$x=0,-2,-3$

<h2>Step-by-step explanation:</h2>

We are given a function f(x) by:

$f(x)=x^3+5x^2+6x$

We know that the zeros of the function f(x) are the possible values of x at which the function is equal to zero.

Hence, when f(x)=0 we have:

$x^3+5x^2+6x=0\\\\i.e.\\\\x^3+3x^2+2x^2+6x=0\\\\i.e.\\\\x^2(x+3)+2x(x+3)=0\\\\i.e.\\\\(x^2+2x)(x+3)=0\\\\x(x+2)(x+3)=0\\\\i.e.\\\\x=0\ or\ x=-2\ or\ x=-3$

A sign painter paints individual numerals for a row of 50 houses. The houses are numbered with consecutive integers from 1 to 50

Iteru [2.4K]

Answer: 5

List out the numbers from 1 to 50. Then go through that list and circle any numbers that have 9 in them. Those numbers are:
9, 19, 29, 39, 49
So there are 5 houses with 9s painted

your expenses total $5.600 per month. you charge$25 per hour and have contracts for steady work that total 45 hours per week for

bulgar [2K]

Answer

58,432 money you have leftover or $8,700 still left to pay.

Step-by-step explanation:

After knowing the contracts for steady work is 45 hours per week I just divided it by the days she works a week, which is most likely 5 and got 9 hours a day, then did $25 * 9 to get the payment per day which is $225 then multiplied it by 5 for the days working in a week, then multiply it again by 52 to get $58,500 as your payment and if your expenses is $5.6 per month (5.6*12=67.2) then your payment cover all of it and you still have $58,432.8 remaining, but if the expenses are $5,600 a month (5,600*12=67,200) then you cover most of it but still have to pay $8,700
