Answer:

A. 2^11

Step-by-step explanation:

The exponent rule you want to use here is that, when multiplying numbers with the same base, you add their exponents and keep the base. Here, you're explicitly being told to multiply 2^4 and 2^7, meaning you should add 4 and 7 and make the sum the power you're raising 2 to. 4 + 7 is 11, so the answer is A. 2^11

B is wrong because you do not multiply the exponents.

C is wrong because there is no multiplication involved at all... strange.

D is wrong because you do NOT multiply the base. Keep it!

Answer:

  $74,828

Step-by-step explanation:

We assume the numbers in the problem statement here mean the cost of living index is $58,000 in Illinois and $70,000 in California. That means the costs in California are 70/58 = 35/29 times those in Illinois.

In order to maintain the same relative lifestyle, you would need to earn (35/29) times $62,000 in California, or ...

  (35/29)×$62,000 ≈ $74,828 . . . . acceptable CA salary

Answer:

  in the order (5m, 3m, 2m+2), ...

Step-by-step explanation:

There are two possible solutions:

5m is the hypotenuse

  (5m)² = (3m)² +(2m+2)²

  25m² = 9m² +4m² +8m +4

  3m² -2m -1 = 0 . . . . . . . . . . . write in standard form, divide by 4

  (m -1)(3m +1) = 0 . . . . . . . . factor

The positive solution for m is the value that makes m-1=0. It is m=1.

The side lengths are ...

  5m = 5 . . . hypotenuse

  3m = 3

  2m+2 = 4

__

2m+2 is the hypotenuse

  (2m+2)² = (5m)² +(3m)²

  15m² -4m -2 = 0 . . . . . . . write in standard form, divide by 2

Then the solutions using the quadratic formula are ...

  m = (-(-4) ± √((-4)² -4(15)(-2)))/(2(15)) = (4 ± √136)/30 = (2±√34)/15

The positive solution for m is ...

  m = (2+√34)/15 ≈ 0.522063

Then the side lengths of the triangle are ...

  (2m +2) = (34 +2√34)/15 ≈ 3.0441 . . . hypotenuse

  5m = (2 +√34)/3 ≈ 2.6103

  3m = (2 +√34)/5 ≈ 1.5662

Answer:

y = 1 and x = - 6

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( where c is the value of the y- coordinates the line passes through )

The line passes through (- 6, 1 ) with y- coordinate 1 , then

y = 1 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, 1 ) with x- coordinate - 6 , then

x = - 6  ← is equation of vertical line

Answer:

or

[tex](2,4)[/tex]

Step-by-step explanation:

1. Rewrite as:

[tex]x+3x-2=6\\y=3x-2[/tex]

2. Simplify the left side.

[tex]4x-2=6\\y=3x-2[/tex]

3. Add 2 to both sides of the equation.

[tex]4x=8\\y=3x-2[/tex]

4. Replace all occurrences of x with 2 in each equation.

[tex]y=4\\x=2\\(2,4)[/tex]

===================================================

Explanation:

The confidence interval is centered at the mean of 42. We add and subtract the margin of error (MoE) from this center to get the left and right endpoints of the confidence interval.

The 99% confidence interval is (39.90, 44.10)

This is the same as writing [tex]39.90 < \mu < 44.10[/tex]

We are 99% confident the mean mu is somewhere between 39.90 and 44.10, excluding both endpoints.

Answer:

  A. Y-5 = -8(x + 2)

Step-by-step explanation:

The given line has a slope of -8, which is the value of the x-coefficient.

The equation you're looking for will be of the form ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m=-8 and (h, k) = (-2, 5), the point-slope equation will be ...

  y -5 = -8(x +2) . . . . matches choice A

Answer:

35/4,293 = 8.152806895

Step-by-step explanation:

When we say that a number is being divided by other, we say this number is the numerator. The number by which the numerator will be divided is called the denominator. In your question, this will mean that 35 will be the numerator and 4.293 is the denominator.This are the parts of a fraction, were the numerator will be at the top and the denominator will be at the bottom. There are different methods for dividing, but due to the complexity of this exercise shown, it is preferable the use of a calculator. You may have one physically or if not, you can access to one digital calculator from an electronic device such as your smartphone, computer or tablet.

Me, as a high-school student prefer using a physical scientific calculator because it has a great variety of functions, making it useful for math and science roots of physics, biology and chemistry, but you can also find a scientific calculator digitally.

Hope this is useful!

The quotient represents 35 divided by 4.293, as follows:

35 ÷ 4.293 = 8.1588

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To solve 35 divided by 4.293, we would use the division operator (/) in a mathematical calculation. The result would be 8.1588.

Here is the calculation:

35 ÷ 4.293 = 8.1588

The division operator takes the numerator (35) and divides it by the denominator (4.293) to give us the quotient (8.1588). This quotient represents the number of times the denominator "fits into" the numerator.
