A parabola has focus (5,1) and directrix y=-3.
Where is the parabola’s vertex?
Answer:
vertex = (5, - 1 )
Step-by-step explanation:
The focus and directrix are equidistant from the vertex
Since the equation of directrix is y = - 3 then the parabola is vertical,
The distance between the focus and directrix is
| 1 - (- 3) | = | 4 | = 2
Thus the vertex is 2 units below the focus
vertex = (5, 1 - 2 ) = (5, - 1 )
A parabola has focus (5, 1) then the vertex of the parabola will be (5, -1).
What is a Parabola?A location on the curve that is equally spaced from both a fixed location and a fixed line is referred to as a parabola. The parabola's focus requires and fixed line are referred to as its foci and directrix, respectively.
As per the given information in the question,
The focus and directrix are equidistant from the vertex then,
The parabola is vertical because the directrix's equation is y = - 3; hence, the focus and directrix are separated by:
|1 - (-3)| = |4| = 2
The vertex is therefore 2 units below the focus.
vertex = (5, 1 - 2) = (5, -1)

A $30 sweater is on sale for 20% off at Kohls. The same $30 sweater is on sale at Macy's for $5 OFF the price. What is the difference in sale prices between the two stores
Which store has the sweater in the above question for the better price ?
Answer: You can save 15% or more on car insurance when you switch to Geico
Step-by-step explanation:
The difference in sale prices between the two stores is $4.5.
What is discount?A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.
Given that, a $30 sweater is on sale for 20% off at Kohls.
Here, sales price = 30-20% of 30
= 30-20/100 ×30
= 30- 0.2×30
= 30-6
= $24
The same $30 sweater is on sale at Macy's for $5 off the price.
Here, sales price = 30-5% of 30
= 30-5/100 ×30
= 30- 0.05×30
= 30-1.5
= $28.5
So, difference in price = 28.5-24
= $4.5
Therefore, the difference in sale prices between the two stores is $4.5.

If y varies jointly as x and z and y = 4 when x = 2 and z = 3, what is y when x = -6 and z = 2?
Answer:
Step-by-step explanation:
Y = kxz
Putting values of y x and z in the equation
4 = k(2)(3)
4 = k6
2/3 = k
Now finding y when x = - 6 and z = 2
Y = kxz
= 2/3(-6)(2)
= - 8

Find the greatest common factor of 4c3 and 6m2.
Answer:
The GCF is 2
Step-by-step explanation:
Here, we want to find the greatest common factors of the two terms
We have the terms written in terms of the products of their multiples as follows;
4c^3 = 2 * 2 * c * c* c
6m^2 = 2 * 3 * m * m
As we can see, the greatest common factor of the two is simple the value 2
A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2

A function assigns the values. The value of (5r+1/5)² when the value of r is 0 equals 0.04.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function g(r)=(5r+1/5)², therefore, the value of the function when r=0 will be,
g(r) = (5r+1/5)²
g(0) = [5(0)+1/5]²
g(0) = (1/5)²
g(0) = 1/25
g(0)=0.04
Hence, the value of (5r+1/5)² when the value of r is 0 equals 0.04.

Yes, the median is 49.5, Q1 is 41, Q3 is 52 (I always have to check)
So the box should start at Q1, end at Q3, and have it's middle line on the median. For this data set, box should start on 41, end on 52, and have its inner line on 49.5.
Of your choices, that's option C.

Diego props a 10ft ladder against the wall how high up will the ladder reach if the foot of ladder is 5 feet away from the wall ?
Answer:
5√3 ft
Step-by-step explanation:
If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:
a²+b²=c²
(5)²+b²=(10)²
25+b²=100
b²=75
b=√75
b=5√3
So the ladder will reach a height of 5√3 ft.
