Enter your answer by filling in the boxes. Enter coordinates as simplifed fractions or radicals in simplest form.
Answer:
ler we have a point (x, y) and,
in molar form°
Z = √(x² + y² ) and 0 = tan-¹(y/x).
Since the point (2√3, -2) is in the fourth quadrant, make certain that your angle is also in the fourth quadrant.

A store is having a sale where customers can buy one shirt and get a second shirt for 30% off. Kate wants to buy two shirts priced at $19 each. How much will she pay?
Answer:
$32.3
Step-by-step explanation:
First write 30% in the decimal form
30/100 = 0.3
than the equation written in the form
x = 19 + (19 - 0.3× 19)
x = 19 + ( 19 - 5.7)
x = 19 + 13.3
x =$ 32.3
So, Kate will pay $32.3

True or False:
x2 and -2x2 are like terms
Answer:
true i think....
Step-by-step explanation:
like terms have the same variables but don't need to have the same coefficients.
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

8. The soccer ball has a diameter of 9 inches. Find its volume.
Answer:
You do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3.
Step-by-step explanation:
Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?
y = 2 (x + seven-halves) squared minus one-fourth
y = 2 (x + seven-halves) squared minus one-half
y = 2(x + 7)2 – 73
y = (x + 7)2 – 24
Answer:
The person above is correct B)y=2(x+7/2)²+1/2
Step-by-step explanation:
y = 2 (x + seven-halves) squared plus one-fourth equation is y = (x + 3)² + (x + 4)² rewritten in vertex form.
What is vertex form?If the vertex is (a, b), then the vertex form of an equation can be written as y = p(x-a)² + b, p is a constant.
How to solve this problem?Here, y = (x + 3)² + (x + 4)²
i.e. y = x² + 6x + 9 + x² + 8x + 16
i.e. y = 2x² + 14x + 25
i.e. y = 2x² + 2*2*(7/2)x + (7/2)² - (7/2)² + 25
i.e. y = 2(x + 7/2)² + 25/2 - 49/4
i.e. y = 2(x + 7/2)² + (50 - 49)/4
i.e. y = 2(x + 7/2)² + 1/4
Therefore, y = 2 (x + seven-halves) squared plus one-fourth equation is y = (x + 3)² + (x + 4)² rewritten in vertex form.
So, no option is correct.

can someone solve Pythagorean theorem
Answer:
48 units
b= 48 units
Step-by-step explanation:
pythag is [tex]a^2+b^2=c^2[/tex]
we have a and c
so substitute them in
[tex]14^2+b^2=50^2[/tex]
now you can solve
[tex]196+b^2=2500[/tex]
subtract 196 from both sides
[tex]b^2=2500-196[/tex]
subtract
2500 - 196 = 2304
[tex]b^2=2304[/tex]
solve for the square root
square root of 2304= 48
therefore b= 48 units

A shipping company selects 75 random packages to check their weight.It finds that 3 packages were weighed incorrectly. How many packages out of 3000 should the company predict have an incorrect weight?
Answer: 120 Packages
Step-by-step explanation:
Given
75 random packages are check
3 package is found faulty
So, the percentage of error is
[tex]\Rightarrow \dfrac{3}{75}\times 100=4\%[/tex]
i.e. 4% packages is faulty
For 3000 sample, expected faulty packages are

Answer:
a) y = -2/5x + 3 b) (20, 19)
Step-by-step explanation:
a) slope of PQ => 24-9/22-16 = 15/6 = 5/2
perpendicular line have negative reciprocal slope = -2/5
substitute the new slope -2/5(m) and (5, 1) into the equation: y = mx + c to find the value of c
=> 1 = -2/5(5) + c
=> c = 3
plug in both the slope -2/5(m) and b = 3 into the equation: y = mx + c
=> y = -2/5x + 3
b) (2/3(22 -16), 2/3(24 - 9))=> (4, 10)
(16, 9) + (4, 10) = (20, 19)

The school supply store is selling two different sizes of similar folders. The smaller folder is 6 inches wide and 9 inches
tall. The larger folder is 12 inches tall.
What is the perimeter of the larger folder?
Answer:
The perimeter of the larger folder is 40 in
Step-by-step explanation:
This is because it says the two folders are similar this means that the width of the larger folder is 8 inches because the scale factor is 4/3. You can see this when you divide the length of the larger folder by the length of the smaller folder. So, if you solve 8+12+8+12 to find the perimeter you will get 40 inches

Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb
