identity the vertex, focus, and directrix
Answer:
vertex: (0, 0)
focus: (-7, 0)
directrix: x=7
Step-by-step explanation:
divide both sides by (-1/28) and you will get y^2=-28x-28=-4p ----> p=7focus=(-p, 0) ------> (-7, 0)directrix=x=p ---------> x=7Find the sum of 13x+5 and 8+25x.

A circle has a radius of 5p6q3 cm. The area of the circle can be found using the formula A = πr2. What is the area of this circle in square centimeters?
Answer:
25p^12q^6πcm²
Step-by-step explanation:
Given the area of the circle expressed as;
A = πr^2
Given
r = 5p^6q^3 cm
Substitute into the formula
A = π(5p^6q^3 )²
A = π(25p^12q^6)
A = 25p^12q^6πcm²
hence the area of this circle in square centimeters is 25p^12q^6πcm²
The area of the circle whose radius be 5p⁶q³ is 25πp¹²q⁶ square centimeters.
What is a circle?It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circle has a radius of [tex]\rm 5 \ p^6 \ q^3[/tex] cm.
The area of the circle can be found using the formula
[tex]\rm A = \pi \ r^2[/tex]
Then the area of the circle will be
[tex]\rm A = \pi (5 \ p^6 \ q^3)^2\\\\A = \pi * 5^2 \ (P^6)^2 (q^3)^2\\\\A = 25 \ \pi \ p^{12} \ q^6[/tex]
Thus, the area of the circle is 25πp¹²q⁶ square cm.

The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
What is the notation?
Answer:
0.6710
Step-by-step explanation:
The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 107 mm
σ is the population standard deviation = 5 mm
For x = 104 mm
z = 104 - 107/5
z = -0.6
Probability value from Z-Table:
P(x = 104) = 0.27425
For x = 115 mm
z = 115 - 107/5
z = 1.6
Probability value from Z-Table:
P(x = 115) = 0.9452
The probability that the diameter of a selected bearing is between 104 and 115 millimeters is calculated as:
P(x = 115) - P(x = 104)
0.9452 - 0.27425
= 0.67095
Approximately = 0.6710
Find a and b.........
Answer:
a is 10
b is 37
Step-by-step explanation:
Now we must agree that the diagram above is a parallelogram.
this figure has its opposite sides parallel to each other, and also equal to each in length, this means a+5=15.
hence a is 10.
and the opposite angles of the parallelogram are equal thus, 111=3b,
hence b is 37°.
I must say I was shocked to see 111 is divisible by 3...

a spherical snow globe has a diameter of 4 inches. what is the volume, in cubic inches, of the spherical part of the snow globe
Answer:
The volume of the snow globe is 78 cubic inches.
Step-by-step explanation:
Given:
A snow globe consists of a pedestal in the shape of a cube with a sphere mounted on top of the pedestal. The pedestal has an edge length of 4 inches and the sphere has a diameter of 3 inches.
Now, to get the volume of the snow globe.
So, we get the volume of pedestal which is in the shape of cube by putting formula:
Edge = 4 inches.
Volume of pedestal = 64 cubic inches.
Now, to get the volume of sphere by putting formula:
Diameter = 3 inches.
Radius () =
Volume of sphere = 14.131 cubic inches.
Now, to get the volume of snow globe by adding both the volumes, the volume of sphere and the volume of pedestal:
Rounding to the nearest cubic inch = 78 cubic inches.
Therefore, the volume of the snow globe is 78 cubic inches.
Find the value of x.
