measure of angle CED?

Answer:

The 1st option

Step-by-step explanation:

The base of a logarithm is always the base of an exponent. The log of part would always be the final powered form of the exponent. So, 2 would be the base, 16 would be logged, and 4 would be your answer.

Answer:

f^-1(x) = (x-8)/4

Step-by-step explanation:

To find an inverse function, simply flip the x and y variables in a equation and then solve in terms of y.

x = 4y + 8

x - 8 = 4y

y = (x-8)/4

And we have our final answer!

Answer:

25

Step-by-step explanation:

The correct value can be calculated by doing (b/2)²

In this expression, it would be (-10/2)²

Which equals 25

Answer:

x^2 -10x+25

Step-by-step explanation:

Take the coefficient of x

-10

Divide by 2

-10/2 =5

Square it

Add this to make a perfect square trinomial

x^2 -10x+25

Answer:

35

Step-by-step explanation:

We first need to find the missing side of the base triangle.  

15^2 - 9^2 = x

144 = x^2

x = 12

Then, we can use the same formula (Pythagorean theorem) to find BD.  

37^2 - 12^2 = x

1225 = x^2

x = 35

Answer: x=-1.9

Step-by-step explanation:

divide 7 on both sides

[tex]x=-1.9[/tex]

Answer

solution

[tex]5x + 18 + 2x = 5 \\ or \: 5x + 2x + 18 = 5 \\ or \: 7x + 18 = 5 \\ or7x = 5 - 18 \\ or \: 7x = - 13 \\ \: x = - \frac{13}{7} [/tex]

X=-1.9

Answer:

f(x)= 20,000[tex](0.85)^{x}[/tex]or 20,000 (0.85) to the power of x.

Step-by-step explanation:

 Okay, so based on the question, we know that the car is depreciates its value every year. In case you don't know, when something depreciates, it is becoming smaller or less in value. It comes to a point where the item becomes worthless. Recall, that the formula for an exponential function is y= a(b) to the power of x. A is your initial value or your y-intercept. B is the multiplicative rate of change. Lets put 20,000 for a because that is value of the car that terrace purchased before any depreciation happened. Since it says that it is decaying every year, we don't want to graph how much it is decaying, we want to graph what the value is of the car. So, do 100 percent minus 15 which is 85 percent. You need to change it into decimal, so it is 0.85. Therefore, there is your function.

Answer:

Angle x measures 64 degrees and Angle y also measures 64 degrees. X is 11. The value of y is also 11.

Step-by-step explanation:

Alright, so this triangle is an isosceles triangle since there are lines on two sides meaning they are congruent to each other. So, if the sides are congruent, then the angles are also congruent. Angle y is congruent to angle x. First, lets find what they measure totally. Since they are congruent, we can write the equation with 2x+angle w which is 52=180 because the sum of all angles in a triangle is 180. Subtract 52 from both sides 2x=132 divide both sides by 2, and you get 64. You found what angle x and y equal. Now you can find what the value of x and y. For finding x, 4x+20=64 and for y, 6y-2=64. Isolate each variable, and you get 11 for both the value of x and y.

Answer:

-374

Step-by-step explanation:

We know that a₁ = 14 and the common difference = -4 so the explicit rule is aₙ = 14 + (n - 1) * (-4) = -4n + 18. a₉₈ = -4 * 98 + 18 = -374.

Answer:

Answer:

0.9432

Step-by-step explanation:

Given that

[tex]\\Mean (\mu)= 45[/tex]

[tex]Standard\;Deviation (\sigma)= 5[/tex]

Based on this, the proportion of the shirt price between the given range is

As we know that

For 37 dollars

[tex]z_{ score } = \frac{x-\mu}{\sigma}[/tex]

[tex]z = \frac{37.0-45.0}{5.0}[/tex]

[tex]z_1 = -1.6[/tex]

For 59.35 dollars

[tex]\\ z = \frac{59.35-45.0}{5.0} \\[/tex]

[tex]z_2 = 2.87[/tex]

This results into

= P(37.0 < x < 59.35)

= P(-1.6 < z < 2.87)

= P(Z < 2.87) - P(Z < -1.6)

So,

= P(37.0 < x < 59.35)

= 0.9979 - 0.0547

= 0.9432

Answer:

−8, 19

-5, 10

Step-by-step explanation:

The points that are on the perpendicular bisector of the given segment is (-5, 10)

Perpendicular bisector is defined as a line that divide an angle into  two equal parts at 90 degrees.

The standard equation of a line in point-slope form is expressed as

y-y₁ = m(x-x₁)

First, we need to get the equation of the line using the coordinates (-20, 0) and (10, 15)

Get the slope of the line

m = 15-0/10-(-20)

m = 15/30

m = 1/2

The slope of the line perpendicular to the line is -2

Using the point (-5, 10) on the line, get the equation in the point-slope form:

y - 10 = -2(x + 5)

y - 10 = -2x - 10

y + 2x = -10 + 10

y + 2x = 0

y = -2x

To check which points are on the perpendicular bisector of the given segment, hence;

For the coordinate (-8, 19)

19 = -2(-8)

19 ≠ 16 (This is not a solution)

For the coordinate (1, -8)

-8 = -2(1)

-8 ≠ -2 (This is not a solution)

For the coordinate (-5, 10)

10 = -2(-5)

10 = 10 (This is a solution)

Hence, the point that is on the perpendicular bisector of the given segment is (-5, 10)

Answer: $20

Step-by-step explanation:

Here os the correct question:

Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?

Let the original price of the perfume be y.

Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:

y - (25% of y) = $15

y - (25/100 × y) = $15

y - 0.25y = $15

0.75y = $15

Divide both side by 0.75

0.75y/0.75 = $15/0.75

y = $20

The original price of the perfume is $20

The general form of the equation of the circle will be x² + y² − 8x − 4y + 11 = 0.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x - h)² + (y - k)² = r²

The standard form of the equation of a circle is (x − 4)² + (y−2)² = 9

Then the general form of the equation of the circle will be

x² + 4² − 8x + y² + 2² − 4y = 9

      x² + y² − 8x − 4y + 20 = 9

        x² + y² − 8x − 4y + 11 = 0

Then the correct option is A.
