Answer:
Step-by-step explanation:
y=ax^2+bx+c we are given point (0,5) so if x=0, y=c, so c=5. We have two other points
(2,3)(4,9) which gives us
4a+2b+5=3 and 16a+4b+5=9
Subtracting twice the first from the second
16a+4b+5-8a-4b-10=9-6
8a-5=3
8a=8, so a=1, so using 4a+2b+5=3 we get
4(1)+2b+5=3
2b+9=3
2b=-6
b=-3 so our quadratic is
y=x^2-3x+5

The Martin family has three children. One is in elementary school, one is in middle school, and one is in high school. They are moving and would like to
live at a location that is the same distance from each of the three schools. They have mapped the schools in a coordinate plane. Determine the
coordinates of the best location that will be equidistant from all three schools.
Answer:
Answer is 1/2,-1 1/2
Step-by-step explanation:
The coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).
What is circumcenter of a triangle?The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. In other words, the point of concurrency of the bisector of the sides of a triangle is called the circumcenter.
The coordinates of the 3 points that form a triangle attached in the image are;
A(-4, -2), B(0, 3), C(5, -1)
Since the distances to the circumcenter O from the vertices are all equal.
Then; AO = BO = CO.
From the first equality, we have AO² = BO²
(x + 4)² + (y + 2)² = (x - 0)² + (y - 3)²
⇒ 8x + 16 + 4y + 16 = – 6y + 9
⇒ 8x + 10y = -23 ---(1)
Similarly, from the second equality, we have BO² = CO²
(x - 0)² + (y - 3)² = (x - 5)² + (y + 1)²
⇒ – 6y + 9 = -10x + 25 + 2y + 1
⇒ 10x - 8y = 17 ----(2)
Solving eq 1 and 2 simultaneously gives;
x = -0.085
y = -2.232
Therefore, the coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).

c. 16π (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)
d. 4π (That section is a semicircle, so length should be 1/4 the circumference)

A closed rectangular tank measures 5 meters by 10 meters by 6 meters. What is the surface area of the tank?
Answer:
280 square units
Step-by-step explanation:
Using the given dimensions {5, 6, 10}, find the area of the front, top and end of the box: 5*6 + 5*10 + 6*10 = 140 square units.
The back of the box is the same size and shape as the front, the bottom the same as the top, and the other end the same as the first end. Thus, multiply 140 square units by 2 to get the total surface area of the tank:
It is 280 square units.

Answer:
the answer is 2.87
Step-by-step explanation:
use the pythagorean theorem
2^2+b^2=4^2
that goes to b= 3.5
for the triangle with x you also need to use the pythagorean theorem
[tex]2^{2}[/tex]+[tex]x^{2}[/tex]=[tex]3.5^{2}[/tex]
4+[tex]x^{2}[/tex]=12.25
subtract 4 on both sides
[tex]x^{2}[/tex]=8.25
[tex]\sqrt{x}[/tex]=[tex]\sqrt{8.25}[/tex]
x=2.87

What is Exponential Function?The formula for an exponential function is f (x) = axe, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Given equation
64w¹⁸z¹²
so factors of 64 = 2 x2 x 2 x2 x 2 x2
64 = 2⁶
the equation is 2⁶w¹⁸z¹²
Hence the value of equation is 2⁶w¹⁸z¹².
