An exponential function in the form y=64(b)x contains the points (0,64) and (3,1). What is the value of b?

Answer:

ninety eight thousand two hundred forty eight

Answer:

Ninety-eight-thousand-and-two-hundred-and-forty-eight

Step-by-step explanation:

In accordance with the query, we have 12.6% of $58.20. The closest tenth of one percent.

It really is 100 * 20 / 100 = 20percent . In this circumstance, percentages are useful. When describing a change from one % to another, we use percentage points. The difference between 10% and 12% is four percent respectively (or 20 percent).

Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary, we have following :

$7.30 is what percent of $58.20.

rate = (7.30 / 58.20) * 100

rate = 0.126034483 * 100 = 12.6%

Rounding to the nearest tenth of a percent, the rate is 12.6%.

So $7.30 is 12.6% of $58.20.

Answer:

x = X + 33 (I am guessing "x" and "X" are not the same. "x" is a variable and "X" is a constant.)

Step-by-step explanation:

31 - X + (2x+1) = x - 1

or, 2x+1 = x - 1 - 31 + X

or, 2x - x = -1 -31 + X -1

or, x = -2 -31 + X

or, x = X - 33

For the translation find the distance between corresponding points of A and A'. It is 5 units.

We see the figures A' and A'' are symmetrical and the sides on the x-axis overlap. It means the center of dilation is the origin, the point (0, 0).

Answer:

  A. d + j = 21,000; 2d − 2,000 = j

  d = $7,666.67; j = $13,333.33

Step-by-step explanation:

The relationships given in the problem statement are ...

  d + j = 21,000 . . . . .  the total of the two loans is $21,000

  2d -2000 = j . . . . . . Jen's is $2000 less than twice David's

__

These equations can be solved by substituting for j:

  d +(2d -2000) = 21000

  3d = 23000 . . . . . . . . . . . add 2000, collect terms

  d = 23000/3 = 7666.67 . . . divide by the coefficient of d

  j = 21000 -d = 21000 -7666.67 = 13333.33

Jen's loan is $13,333.33; David's loan is $7,666.67.

The slope is [tex]\frac{9}{16}[/tex]

Step-by-step explanation:

Hi there!

We are given the points (29, 11) and (-3, -7), and we want to find the slope of them.

The slope can be calculated from two points with the slope formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

We have two points given, but let's label their values to avoid any confusion when we actually calculate:

[tex]x_1=29\\y_1=11\\x_2=-3\\y_2=-7[/tex]

Now substitute into the formula (m is the slope).

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-7-11}{-3-29}[/tex]

Subtract

m=[tex]\frac{-18}{-32}[/tex]

Reduce the fraction

m=[tex]\frac{9}{16}[/tex]

The slope is [tex]\frac{9}{16}[/tex]

Answer: The new scale factor needs to be 10/3

Explanation:

Consider a line segment that is 10 units long. Apply the scale factor 3/10 to it, and now it's 3 units long because (3/10)*10 = 3.

To get it back to 10 units, we multiply by the scale factor 10/3 which is the reciprocal of the original scale factor. Note that (3/10)*(10/3) = 1. Those two scale factors multiply to 1 to indicate no change has been made overall.

Answer:

The slope is -5/3.

The y-intercept is (0,10).

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Since -5/3 is in the place of m, the slope, that makes -5/3 the slope.

3. The y-intercept of a graph is the point where the graph intersects/crosses the y-axis. The x-coordinate of a point in any y-intercept will ALWAYS be 0.

4. Since 10 is in the place of b, the y-intercept, and given the information above, the y-intercept is (0,10).

Using a system of equations, it is found that 595 students picked Science as their favorite subject.

For our system, we suppose that x is the number of students that picked science, and y is the number of students that picked math.

Ratio of science to math of 3:5, thus:

[tex]\frac{x}{y} = \frac{3}{5}[/tex]

Then

[tex]5x = 3y[/tex]

[tex]x = \frac{3y}{5}[/tex]

238  more students picked Math as their favorite subject, thus:

[tex]y = 238 + x[/tex]

[tex]y - \frac{3y}{5} = 238[/tex]

[tex]\frac{2y}{5} = 238[/tex]

[tex]y = \frac{238(5)}{2}[/tex]

[tex]y = 595[/tex]

Answer:

Move the decimal point in 407.26 three places to the left = 0.407283

Step-by-step explanation:

Answer:

3, left

Step-by-step explanation:

When you're dividing a number by any power of 10 that is a whole number (10, 100, 1000, etc.), you move the decimal point to the left as many times as there are zeroes in the digit.

Examples:

30.22 ÷ 100 = 0.3022

There are two zeroes in 100, so move the decimal point two spaces to the left.

568.9 ÷ 10000 = 0.05689

There are four zeroes in 10000, so move the decimal point four spaces to the left.

The given equation in the problem is 407.26 ÷ 1000, so you move the decimal point 3 spaces to the left to find the correct answer.
