Answer:

  • x - 4

Step-by-step explanation:

  • V(x) = x³ - 8x² + 19x - 12

<u>The two of the dimensions given</u>

  • (x - 1) and (x - 3)

<u>and the third one is</u>

  • x + a

<u>Multiply the three dimensions to get the volume:</u>

  • (x - 1)(x - 3)(x + a) =
  • (x² - 4x + 3)(x + a) =
  • x³ - 4x² + 3x + ax² - 4ax + 3a =
  • x³ - (4 - a)x² + (3 - 4a)x + 3a

Comparing with the given function, we get a = - 4

<u>So the missing dimension is:</u>

  • x - 4

Q11) kelly puts $350 in a savings account. the savings account accrues interest at a flat rate of 1.05% a month. how much will t
Leviafan [203]

The account be worth in 7 months is 375.725 .

<h3>What is the amount in simple interest?</h3>

Amount (A) is the total money paid back at the end of the time period for which it was borrowed. The total amount formula in case of simple interest can also be written as: A = P(1 + RT)

Here, A = Total amount after the given time period.

Given that,

P = $350, R = 1.05%, T = 7 month

The simple interest equation uses "t" as years, but is just cycles, using an APR rate.

now, if we never mind "t" as years and just use it as an interest cycle, then we can say the rate is 1.05% and the period is 7 cycles.

A = P(1 + RT)

   = 350(1+1.05%×7)

   = 350(1+0.0105×7)

   = 350(1+0.0735)

   = 350×1.0735

A  = $375.725

Hence, The account be worth in 7 months is 375.725 .

I dont understand how do this question.<br><br><br>There is a picture.​

Answer:

  b⁶

Step-by-step explanation:

The question tells you how to work it: use the relations you studied.

Here, you have the power of an expression with an exponent. The exponents multiply.

  \text{Rule: }(a^b)^c=a^{bc}\\\\\text{Appication: }(b^3)^2=b^{3\cdot2}=\boxed{b^6}

_____

<em>Additional comment</em>

A coefficient is used to indicate repeated addition: 3x = x + x + x.

An exponent is used to indicate repeated multiplication: x³ = x·x·x.

This is still true when the exponent is applied to an expression with an exponent:

  (b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2

Of course, each of these indicates repeated multiplication, so we really have ...

  (b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b

And this can be simplified using an exponent to show the repeated multiplication:

  = b⁶

Then, by going the long way around, we arrive at ...

  (b³)² = b⁶

3 1/4 plus 2 3/4 help me plz
Ilya [14]
The answer would be 6 because by adding the whole numbers, 3+2, you would get 5 and since the fractions both have denominators of 4, you had both fractions, 1/4+3/4, which gives you 4/4 or 1 whole. 5+1=6 and that's your answer.
Hope I Helped!

a car travels along the highway to yuma at steady speed. when it begins, it is 400 miles from yuma. After 7 hours, it is 59 mile
klemol [59]

Answer:

y= -50x + 400

Step-by-step explanation:

-50 miles from the place which means they are going further and further away so it is negative. And its 400 because y=mx+b the b is 400 because thats where they started.  Also it said it was correct on A-p-e-x.
