a point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.
(5,7)
Answers
Answer:
(√74, 54.46°)
Step-by-step explanation:
The rectangular coordinate point is given as; (5, 7)
Now, converting rectangular coordinates to polar coordinates is done by;
(r, θ)
Where, r is the magnitude while θ is the angle
r = √(5² + 7²)
r = √74
tan θ = (7/5)
θ = tan^(-1) 1.4
θ = 54.46°
Thus,polar coordinate is; (√74, 54.46°)

The cereal box shown below is a rectangular prism.
Answers
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 13 inches, and the length of the base is 8 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch
Answers
Answer:
12.2 inches
Step-by-step explanation:
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 5 inches, and the length of the base is 2 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
The length of the sides of the isosceles triangle can be found from the
given altitude and the length of the base.
The perimeter of the triangle is approximately 35.2 inches.Reasons:
The given parameter are;
The triangle is an isosceles triangle
The altitude cuts the base into two
Length of the altitude, h = 13 inches
Length of the base of the triangle, l = 8 inches
Required:
Find the perimeter of the triangle.
Solution:
By using the Pythagorean theorem, we have;
Length of one of the isosceles sides of the triangle which is an hypotenuse
side of the right triangle formed by the altitude, R, is given as follows;
[tex]\displaystyle R = \mathbf{\sqrt{ h^2 + \left(\frac{l}{2} \right)^2}}[/tex]
Therefore;
[tex]\displaystyle R = \sqrt{ 13^2 + \left(\frac{8}{2} \right)^2} = \mathbf{ \sqrt{ 13^2 + 4^2}} =\sqrt{185}[/tex]
R = √(185) inches
Therefore, the length of the other hypotenuse side = R = √(185) inches
On the original triangle, the sides are; R, R, and l
Which gives;
The perimeter of the triangle, P = R + R + l = 2·R + l
Therefore;
P = 2 × √(185) + 8 ≈ 35.2
The perimeter of the triangle, P ≈ 35.2 inches.

Which statements about liquid volume are true?
Select each correct answer.

Milliliters are smaller units than liters.
One liter is 1,000 times larger than one milliliter.
One milliliter is 100 times larger than one liter.
One liter is 1,000 times smaller than one milliliter.
Answers
Answer:
C, D
Step-by-step explanation:
These are the only correct statements about liquid volume. 1L= 1,000mL
A Liter is larger than a mL, a thousand times so.
A mL is smaller than a Liter, a thousand times so.
The correct statements about liquid volume are:
1. One milliliter is 100 times smaller than one liter.
2. Milliliters are smaller units than liters.
3. One liter is 1,000 times larger than one milliliter.
1. One milliliter is 100 times smaller than one liter:
This statement is true.
Since there are 1,000 milliliters in one liter, dividing one liter by 1,000 gives us the equivalent value of one milliliter.
2. Milliliters are a smaller unit of measure compared to liters. There are 1,000 milliliters in one liter, so any given volume in milliliters will be a fraction of the equivalent volume in liters.
3. As mentioned earlier, there are 1,000 milliliters in one liter.
Therefore, one liter is 1,000 times larger than one milliliter.
4. Liters are larger units of measure compared to milliliters.
5. As explained earlier, one milliliter is 100 times smaller than one liter.
