Answer:
Complex conjugate: 2i Product: -2iWHATS X AND Y??
Y = 3x+ 4 and 2x – 4y = -6
Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
NEED HELP ASAP ANSWER PLEASEEE!!!
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.
c. Using this rule, where would be located if translated 11 units to the right and 4 units up?
(d) translating pentagon 3 units up and then reflecting it over the x-axis
a. Graph the new pentagon when pentagon is translated 3 units up and reflected over the x-axis. What are the coordinates of pentagon ?
b. Write a math rule or explanation using words that describe a translation of 3 units up and reflection over the x-axis.
c. Using this rule, where would be located if translated 3 units up and reflected over the x-axis?
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
Answer:
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.

ASAPPP! An arrow is shot into the air. A function representing the relationship between the number of
seconds it is in the air, t, and the height of the arrow in feet, h, is given by the equation below.
What is the initial height of the arrow?
h(t) = -16t^2+ 128t + 1.5
Answer:
The initial height of the arrow is 1.5 feet above the ground.
Step-by-step explanation:
Let be the height of the arrow be represented by the function [tex]h(t) = -16\cdot t^{2}+128\cdot t + 1.5[/tex], where [tex]h(t)[/tex] is the current height of the arrow, measured in feet, and [tex]t[/tex], is the time, measured in seconds.
Mathematically speaking, the initial height is the value of [tex]h[/tex] evaluated at [tex]t = 0\,s[/tex]. That is:
[tex]h(0) = -16\cdot (0)^{2}+128\cdot (0) + 1.5[/tex]
[tex]h(0) = 1.5\,ft[/tex]
The initial height of the arrow is 1.5 feet above the ground.

You sign up for karate classes. The classes cost $80 per

m months.
Complete the table for the missing values of d.

Answer:
m* = d**
1 = $80
2 = $160
3 = $240
4 = $320
*months
**Dollars ($)
Step-by-step explanation:
If it costs 80 per month then you times 80 by the number of months you want to work out. For example, you want to work out the cost of going to karate class for 3 months, and it costs $80 per month. Then you do $80 × 3 = $240.
A data set is shown below. Which is the outlier? 56, 64, 73, 59, 98, 65, 59.
Most of the numbers are in the 50’s and 60’s so the outlier would be 98

Answer:
y = -4/3x +23/2
Step-by-step explanation:
The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.
The center of the circle can be found by completing the square for each variable.
(x^2 -2x) +(y^2 +4y) = 20
(x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4
(x -1)^2 +(y +2)^2 = 25
Comparing this equation to the standard form equation for a circle, we can find the center.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)
The center of circle P is (1, -2).
__
The slope m' of the line segment between (1, -2) and (5, 1) is given by ...
m' = (y2 -y1)/(x2 -x1)
m' = (1 -(-2))/(5 -1) = 3/4
The slope m of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/m' = -1/(3/4) = -4/3
The y-intercept of the desired line can be found from ...
b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)
b = 1 -(-4/3)(5) = 23/3
Then the equation of tangent line AB is ...
y = mx +b
y = -4/3x +23/3

The grade seven students are showing a movie in their school auditorium to raise money for the end of year field trip. Goal is to raise at least $500. Each ticket sales for $16. So far they have sold 20 tickets. Which inequality graph correctly shows how many more tickets they need to sell to reach their goal.
Answer:
The answer is A because it needs to be a filled dot to represent the information correctly. 16 x 20 is 320 so they need 180 more to have at least 500 dollars which is 11.25 tickets but you cant have a fourth of a ticket so you need atleast 12 tickets sold.
Where are the minimum and maximum values for f(x)=−2+4cosx on the interval [0,2π]?
Answer:
[tex]f(x) = - 2 + 4 \cos(x) \\ for \: minimum \: \: x = 0 \\ f(0) = - 2 + 4 \cos(0) \\ minimum \: value = 2 \\ for \: maximum \: value \: \: x = 2\pi \\ f(2\pi) = - 2 + 4 \cos(2\pi) \\ maximum \: value = - 2[/tex]
The function is minimum at 3π/2 and the function is maximum at 0 and 2π.
What is the maximum and minimum value of the function?The condition for the maximum will be
f(x)'' < 0
The condition for the minimum will be
f(x)'' > 0
The function is given below.
f(x) = −2 + 4cosx
Differentiate the function with respect to x, then we have
f'(x) = − 4 sin x
Again differentiate the function with respect to x, then we have
f''(x) = − 4 cos x
Then the minimum value of the function will be
f'(x) = 0
−4 sin x = 0
sin x = 0
The value of f''(x) is positive in the interval of (π/2, 3π/2). Then the value of x will be
x = π
Then the maximum value of the function will be
And the of f''(x) is negative in the interval of [0,2π] – (π/2, 3π/2). Then the value of x will be
x = 0 and 2π
More about the maximum and minimum value of the function link is given below.

Quadrilateral ABCD is similar to quadrilateral EFGH. Find the measure of side EF
Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.
