Answer:

Step-by-step explanation:
c is your answer
Answer:
B
Step-by-step explanation:
Expanding the products using FOIL , noting that i² = - 1
A
(2x - 4i)(x - 2i)
= 2x² - 4ix - 4ix + 8i²
= 2x² - 8ix - 8 ≠ 2x² + 8
B
(2x - 4i)(x + 2i)
= 2x² + 4ix - 4ix - 8i²
= 2x² + 8 ← True
C
(2x - 2i)(x + 6i)
= 2x² + 12ix - 2ix - 12i²
= 2x² + 10ix + 12 ≠ 2x² + 8
D
(2x + 4i)(x + 2i)
= 2x² + 4ix + 4ix + 8i²
= 2x² + 8ix - 8 ≠ 2x² + 8
Thus
(2x - 4i)(x + 2i) = 2x² + 8 → B

school lunches cost $14.50 per week. About how much would 5.5 weeks cost of lunches
Answers
Answer:
The answer should be about $81.20
Step-by-step explanation:
$14.50 x 5weeks = $72.50
A school week is usually 5 days.
The middle of the week is Wednesday, so that's 3 whole days.
$14.50 / 5days = $2.90 per day
$2.90 x 3days = $8.70
$72.50 + $8.70 = $81.20
1) Find the inverse of the function below. Use g-1(x) to indicate the inverse 5 points
function. Use SQRT to indicate square root and use parenthesis for
fractions. Example: 9-1(x)=SQRT{(x-2)/3)-6 *
g(x) = 2(x – 3)2 + 4
Your answer
Answers
Answer:
g-1(x)=SQRT{(x-4)/2} + 4
Step-by-step explanation:
I assume that the 2 is the exponent so ^ represents exponent
We know your function is g(x)=2(x-3)^2+4
For inverse functions we swap x and y values, note g(x) is like the y value
Isolate for y
y=2(x-3)^2+4
x=2(y-3)^2+4
(x-4)/2 = (y-3)^2
SQRT{(x-4)/2} + 4 = y
Therefore g-1(x)=SQRT{(x-4)/2} + 4

Step-by-step explanation:
Given the figure below, find the values of x and z.
(10x - 65)
(9x - 49)
Answers
(10x - 65) = (9x - 49)
By subtracting 9x in both sides,
(10x - 9x) - 65 = (9x -9x) - 49
x - 65 = -49
By adding 65 in both sides,
x - 65 + 65= -49 + 65
x = 16
Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.
10 (16) - 65 = 160 - 65 = 95
Now you know that (10x - 65) degrees is equal to 95 degrees,
180 - 95 = z = 85
Answer: x = 16
z = 85

in word for, 5.004 is ____. five thousand, four five and four hundredths five and four thousandths five, four hundredths
Answers
Answer:
In word form, 5.004 is five and four thousandths.
Step-by-step explanation:
The part to the left of the decimal is simple - it's just five.
The part to the right of the decimal is a bit more complicated. The digit one place to the right of the decimal is the tenths place. The digit to the right of the tenths place is the hundredths place. The digit to the right of the hundredths place is the thousandths.
With that in mind, you should find that the number 4 is in the thousandths place. So, your answer is five and four thousandths.

Answers
9514 1404 393
Answer:
x = 3
Step-by-step explanation:
Each line shows you the output value for a given input value. If you want a particular input value to give the same output for both functions, then you need to find the point where the lines cross. This question asks for the input value at that point, the x-coordinate.
The lines cross at (x, y) = (3, -1), so x = 3 produces the same output from both functions.

A 32-ounce package of a snack mix is 24 percent pretzels. How many ounces are pretzels?
0.706 ounces
0.768 ounces
7.06 ounces
7.68 ounces
Answers
Answer:
the correct answer is choice D. if 24 precent of the snack mix is pretzels we simply need to multiply the total number of ounces by 0.24 7.68 ounces of the snack mix will be pretzels
D. 7.68 ounces
Explanation:
What we know:
- the snack mix is 32 ounces
- 24% of the snack mix is pretzels
To find the ounces of pretzels, find 24% of 32 ounces by multiplying them.
24% = 0.24 as a decimal
0.24*32=7.68
Therefore, 7.68 ounces are pretzels.

Solve for x. 5x - 29> -34 OR 2x +31 < 29
Answers
Answer:
x > -1 or x < -1
Step-by-step explanation:
In this question, you would solve the inequalities.
Solve:
Inequality 1:
5x - 29> -34
Add 29 to both sides
5x > -5
Divide both sides by 5
x > -1
Inequality 2:
2x +31 < 29
Subtract 31 from both sides
2x < -2
Divide both sides by 2
x < -1
Your answer would be: x > -1 or x < -1

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?
Answers
Answer:
There are 8 and 12 balloons for groups A and B, respectively.
Step-by-step explanation:
The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:
Group A
[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]
[tex]n_{A} = 8[/tex]
Group B
[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]
[tex]n_{B} = 12[/tex]
There are 8 and 12 balloons for groups A and B, respectively.

a graph passes through the points (0,2),(1,3), and (2,4). Does this graph represent a linear function or a non linear function?
Answers
9514 1404 393
Answer:
linear
Step-by-step explanation:
The slope of the line between the first pair of points is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -2)/(1 -0) = 1/1 = 1
The slope of the line between the second pair of points is ...
m = (4 -3)/(2 -1) = 1/1 = 1
The slopes are the same, so the points are on the same line. The graph is that of a linear function.

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.
Answers
Answer:
Length of side AD is 6.5 units.
Step-by-step explanation:
Let the center of the rectangular base of the given pyramid is O,
From the picture attached,
m∠AOD = 90°
By applying Pythagoras theorem in the right triangle AOD,
AD² = AO² + OD²
AD² = 6² + (2.5)²
AD = √42.25
AD = 6.5 units
Therefore, length of side AD is 6.5 units.

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack. The weight of the blue marlin way 12 times as great of the amberjack. The combined weight of both fish was 273 pounds. How much did each fish weight
Answers
Answer:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds
Step-by-step explanation:
Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack.
Let
The weight of the blue marlin = b
The weight of the amber jack = a
The weight of the blue marlin weigh 12 times as that of the amberjack.
b= 12a
The combined weight of both fish was 273 pounds.
= a + b = 273 pounds
b = 12a
Hence
a + 12a = 273 pounds
13a = 273 pounds
a = 273 pounds/13
a = 21 pounds
b = 12a
b = 12 × 21 pounds
= 252 pounds
Hence:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds
