a quadratic function that fits the points (0,5) (2,3) (4,9)
Answers
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

Mary needs to buy 4 concert tickets and one parking pass. If parking is $12, and she can spend at most $80, what ticket prices can she afford? (set up an inequality, do not solve)
Answers
Answer:
4t + 12 [tex]\leq[/tex] 80
Step-by-step explanation:
Set up an inequality where t is the cost of one ticket
Since her budget is $80, a less than or equal sign needs to be used.
4t will represent the total cost of the tickets, since she needs to buy 4. Add 12 to this to represent the parking cost:
4t + 12 [tex]\leq[/tex] 80 is the inequality.
What is the equation of the line that passes through the point (-8,-6) and
has a slope of 1/4
Answers
Answer:
y = 1/4x -4
Step-by-step explanation:
Since you know that that slope int. equation is y = mx+b, and the m is the slope just plug in the slope in the equation. So it will be y = 1/4x + b.
Then what you will do is solve for b in the equation. So what you do is plug in the x and y value from the coordinate given in the equation, so it will be like this: -6 = 1/4(-8) +b
-6 = -2 +b
-4 = b
b = -4
So then you plug back the b value into the equation with slope to wtite the equation. So it would be, y = 1/4x -4

Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answers
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
18 - 45 = -27
The net of a triangular prism is show below.Find the rotal surface area of the triangular prism 4.6,4,5,15
Answers
Answer:
228.4cm²
Step-by-step explanation:
Find the diagram attached
Total surface area of the prism = Ph + 2B
P is the perimeter of the base (triangle)
h is the height of the prism
B is Base area
P = 5cm + 5cm + 4cm
P = 14cm
h = 15cm
B = 1/2 * base * height
B = 1/2 * 4.6 * 4
B = 4.6 * 2
B = 9.2cm²
Substitute the values into the formula;
Total surface area of the prism = Ph + 2B
Total surface area of the prism = 14(15)+2(9.2)
Total surface area of the prism = 210 + 18.4
Total surface area of the prism = 228.4cm²
Hence the total surface area of the triangular prism is 228.4cm²

b=21
Step-by-step explanation:
For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):
20^2+b^2=29^2
Simplify the squares:
400+b^2=841
Subtract 400 from both sides:
b^2=441
Take the square root of both sides:
b=21

b= 16 mm
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2= c^2, so-
12^2 +b^2= 20^2
144+b^2=400
b^2=400-144
b^2= 256
b= 16
Answer:
16 mm
Step-by-step explanation:
A²+B²=C²
12²+x²=20²
144+x²=400
x²=400-144
x²=256
√x = √256
x = 16
