Answers

Answer: x = 1/16

Step-by-step explanation:

Since the inverse of a Logarithm is an exponential function, we know that the final solution has to involve an exponential function somewhere in it.

1. log B(2) {x} = -4  || given

2. x = 2 ^ -4  || Logarithm rule that allows you to move the base of the logarithm to the base of the exponent on the other side. For example, if you had log B(5) {x} = 3, the base of 5 would move over to the other side and it would be raised to 3; x = 5^3.

3. x = (1) / (2^4) || Simplify. Use the negative exponent rule. This rule always leaves a numerator of 1, and a denominator of your exponent. In this case, it will be 2 ^ -4, so you will do 2^4 which is 16 and you will put that over 1. Resulting in your final answer of x = 1/16

9514 1404 393

Answer:

  316.7 ft³

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3πr²h

Here, the radius (r) is half the diameter, so is 7.7 ft. Then the volume is ...

  V = 1/3π(7.7 ft)²(5.1 ft) = 100.793π ft³ ≈ 316.6505 ft³

The volume of the cone is about 316.7 cubic feet.

_____

If you use the inappropriate value 3.14 for π, your answer will be 316.5 ft³.

1st hour tickets =100%

100%=1280people

120%= ?

=1536 people+1280

=2816people were sold tickets

2816people are the same as 2816tickets

Answer:

Point of intersections are (0, -7) and (5, -2).

Step-by-step explanation:

From the graph attached,

A straight line is intersecting the circle at the two points (0, 7) and (5, -2).

Now solve algebraically,

Equation of the line → y = x - 7 -------(1)

Equation of the circle → (x - 5)² + (y + 7)² = 25 -------(2)

By substituting the value of y from equation (1) to equation (2)

(x - 5)² + (x - 7 + 7)² = 25

(x - 5)² + x² = 25

x² - 10x + 25 + x² = 25

2x² - 10x = 0

x² - 5x = 0

x(x - 5) = 0

x = 0, 5

From equation (1),

y = 0 - 7 = -7

y = 5 - 7 = -2

Therefore, point of intersections are (0, -7) and (5, -2).

1. Minh asks Marco to duplicate a graphic she has on her restaurant’s ceiling. The ceiling is covered with 1 ft by 1 ft tiles. A chandelier hangs in the center of the ceiling. The graphic Minh painted on the ceiling is a pentagon. Assuming that the chandelier is located at , the pentagon’s coordinates are . Minh wants to have the same graphic design duplicated in another location on the ceiling. She is considering four ideas.
(a) reflecting pentagon over the y-axis
a. Graph new pentagon when pentagon is reflected over the y-axis. What are the coordinates of pentagon ?
b. Write a math rule or explanation using words that describe a reflection of over the y-axis.
c. Using this rule, where would be located if reflected over the y-axis?

(b) rotating pentagon 90° clockwise about the origin
a. Graph the new pentagon when pentagon is rotated 90° clockwise about the origin. What are the coordinates of pentagon ?
b. Write a math rule or explanation using words that describe a rotation of 90° clockwise about the origin.
c. Using this rule, where would be located if rotated 90° clockwise about the origin?

(c) translating pentagon to the right 11 units and up 4 units
a. Graph the new pentagon PQRST when pentagon is translated 11 units to the right and 4 units up. What are the coordinates of PQRST?
b. Write a math rule or explanation using words that describe a translation of 11 units to the right and 4 units up.

2. The restaurant floor, like the ceiling, is made of tiles that measure 1 ft by 1 ft. On the floor, Marco has made this graphic.
For each pair of graphics listed below, decide whether the pair is best described as similar, congruent, or neither. If the pair is similar or congruent, describe the sequence of transformations that proves this and write the congruency or similarity statements for each pair of corresponding sides. If the graphics are neither similar nor congruent, explain how you know this.
(a) polygon and polygon
(b) polygon IJK and polygon LMN
(c) polygon and polygon
(d) polygon and polygon

3. Minh wants to add another graphic on the ceiling. She has a pentagon located at . To make the other pentagon, Minh wants to reflect pentagon over the y-axis. Next, she wants to dilate it by a factor of 2, using the origin as the center of the dilation. Finally, she wants to translate it 15 units down and 2 units right to get the location of the final graphic. What is the location of the new graphic? Show your work.
