The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.
Answer:
103Step-by-step explanation:
Given function:
y = -x² + bx + 3The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = -b/2aThe given function has:
x = 10, and a = -1Find the value of b:
10 = -b / -2b = 20The function is:
y = -x² + 20x + 3The y-coordinate of the vertex is:
y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103Answer:
Solution given:
y = -x² + bx + 3
we have
The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = [tex] \frac{ - b}{2a} [/tex]
we have
x = 10, and a = -1
Substituting value of a in -b/2a
we get
b = 20
now
The y-coordinate of the vertex is:
y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

What is the volume of each figure? (Please write the formula and answer)
Answer:
1. (top left corner) = 8km^3
2. (bottom left corner) = 243 in^3
3. (top right corner) = 200 cm^3
4. (bottom right corner) = 3165.12 m^3
Step-by-step explanation:
1. (top left corner) lwh = 4km x 2km x 1km = 8km^3
2. (bottom left corner) (lwh)/3 = (9 x 9 x 8) / 3 = 243 in^3
3. (top right corner) lwh = 5 x 5 x 8 = 200 cm^3
4. (bottom right corner) πr^2h
R = 12
3.14 x 12^2 x 7 = 3.14 x 144 x 7 = 3165.12 m^3
This equilateral triangle has side lengths of 6 inches and a height of approximately 5 inches. Find the area, given these dimensions.
To find the area of a triangle we use this equation:
[tex]\frac{1}{2} bh\\[/tex]
b= base
h= height
So since we are given the information that the sides are 6 and the height is 5 we simply can plug the information right into the equation:
[tex]\frac{(6)(5)}{2}[/tex]= 15
So the are is 15 inches sqaured, hope this helps :)

Esther uses 9.4 pints of blue paint and white paint to paint her bedroom walls. 3 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
3.76
Step-by-step explanation:
Esther uses 9.4 pints of blur paint and white pant for her bedroom
3/5 of this amount is blue paint while the rest is white paint
3/5
= 0.6×100
= 60
Therefore the amount of white paint can be calculated as follows
40/100 × 9.4
= 0.4×9.4
= 3.76

The number of carbon atoms in a fossil is given by the function [tex]y = 5100(0.95)^{x}[/tex], where x represents the number of years since being discovered. What is the percent of change per year? Explain how you arrived at your answer.
Answer:
[tex]\%x=5\%[/tex]
Step-by-step explanation:
From the question we are told that:
Carbon atoms in fossil function
[tex]y=5100(0.95)^x[/tex]
Generally the equation a 2 year change is mathematically given by
For[tex]x=1[/tex]
[tex]y_1=5100(0.95)^1\\y_1=4845[/tex]
For [tex]x=2[/tex]
[tex]y_2=5100(0.95)^2\\y_2=4602.75[/tex]
Generally the equation percentage year changes [tex]\%x[/tex] is mathematically given by
[tex]\%x=\frac{y_1-y_2}{y_1} *100[/tex]
[tex]\%x=\frac{4845-4602.75}{4845} *100[/tex]
[tex]\%x=5\%[/tex]
Therefore the percent of change per year is
[tex]\%x=5\%[/tex]

Find the surface area of the right cone. Round your answer to the nearest hundredth.
The solution is, the surface area of the right cone is 602 cm^2.
What is surface area of a cone?The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr,
where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.
here, we have,
Given that,
The slant height of the cone, l = 16 cm
The radius of the cone, r = 8 cm
The height of the cone is :
h² = l² - r²
or, h² = 16² - 8²
= 192
or, h = √192
= 13.85
now, we know that,
The surface area of the cone is given by :
SA = πr² + πrl
=200.96 + 401.92
= 601.93
=602
Hence, the surface area of the right cone is 602 cm^2.

A rectangular tank with length 50 cm and width 30 cm contains 36 litres of water. Find the depth of the water.
Answer:
24cm
Step-by-step explanation:
Given data
Length=50cm
Width= 30cm
Volume = 36liters
=36000cm^3
We know that the expression for volume is
V= L*W*H
substitute
36000=50*30*H
36000= 1500*H
H= 36000/1500
H= 24cm
Hence the height is 24cm

In Phoenix, Arizona, the average temperature is 85 degrees Fahrenheit or higher during 25% of the year. During about how many weeks of the year is the average temperature below 85 degrees Fahrenheit?
Answer: 39 weeks
Step-by-step explanation:
Given
The average temperature is [tex]85^{\circ}F[/tex] or higher
A year has 52 weeks
It is given 25% of the time-temperature is above [tex]85^{\circ}F[/tex]
So, in the remaining 75% of the weeks, the average temperature is less than [tex]85^{\circ}F[/tex]
No of weeks can be determined by
[tex]\Rightarrow 75\%\ \text{of}\ 52\\\\\Rightarrow \dfrac{75}{100}\times 52=39\ \text{weeks}[/tex]
The formula for finding the volume of a cone is V=
nur?n. The radius of a cone is 5 cm and the height of a cone is 10
cm. What is the approximate volume of the cone?
Answer:
261.8 cm^3
Step-by-step explanation:
1) find the base area
base area = radius^2 x pi = 5^2 x pi = 25 x pi = 78,539816 cm^2
2) find the volume
V = (base area x height)/3 = (78.539816 x 10)/3 = 785.3/3 = 261.8 cm^3
Find the total amount owed, to the nearest cent, for a simple interest loan with a principal of $2950, an interest rate of 7.4% and a time period of 1.5 years. Show your work.
Answer:
Total Accrued Amount = $3,277.45
Interest Amount = $327.45
Step-by-step explanation:
A = $3,277.45
I = A - P = $327.45
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 7.4%/100 = 0.074 per year.
Solving our equation:
A = 2950(1 + (0.074 × 1.5)) = 3277.45
A = $3,277.45
The total amount accrued, principal plus interest, from simple interest on a principal of $2,950.00 at a rate of 7.4% per year for 1.5 years is $3,277.45.
Answer:
Total amount: $3,277.45
Interest: $327.45
Total: 2,950(1 + (0.074 x 1.5)) = 3,277.45
Interest: 3,277.45 - 2,950 = 327.45
