Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
f(x) = 2x2 + 12x + 1
Determine the vertex !
Answer:
(-3, -17)
Step-by-step explanation:
The best way to find the vertex is to rewrite the given quadratic in vertex form: y - k = a(x - h)^2.
The given quadratic is f(x) = 2x2 + 12x + 1. We will focus on the first two terms and "complete the square." f(x) = 2x2 + 12x + 1 can be rewritten as
f(x) = 2(x^2 + 6x) + 1, which, after completing the square, is
f(x) = 2(x^2 + 6x + 9 - 9) + 1, or
f(x) = 2( (x + 3)^2 - 9 ) + 1, or
f(x) = 2(x + 3)^2 - 17
Comparing this to
f(x) = a(x - h)^2 + k, we see that the vertex is located at (h, k): (-3, -17)

x^2-16x+ __
what do we do to find the blank?
We divide 16 by 2 to get 8
then we take the square of 8
which is 64
so this would be x^2-16x+ 64 = 64
REMEMBER 64 goes to BOTH sides of equation

How many solutions does this equation have?
–2 + 2s = –3s + 8
Answer:
Step-by-step explanation:
-2 + 2s = - 3s + 8
-2 - 8 = - 3s - 2s
-10 = - 5s
-10/-5 = s
2 = s
Answer:
2
Step-by-step explanation:
-2+2s=-3s+8
-2+2s-(-3s)=8
-2+2s+3s=8
-2+5s=8
5s=8-(-2)
5s=8+2
5s=10
s=10/5
s=2

Find the perimeter and area of this figure. Plz show work
Answer:
perimeter = 30.56 units
Step-by-step explanation:
perimeter of full circle = 2(4)(3.14) = 25.12
perimeter of semi circle = (25.12)(0.5) = 12.56
perimeter = 12.56 + 10 + 8 = 30.56
A circular fountain has a drain in the center. The distance from the drain to the edge of the fountain is 3 feet. What is the circumference of the fountain? Round your answer to the nearest tenth of a foot.
Answer:
18.8 feet
Step-by-step explanation:
Since the drain is in the center, the distance between the drain and the edge is the radius of the circular fountain.
Use the circumference formula: C = 2[tex]\pi[/tex]r, and plug in 3 as r (the radius).
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](3)
Solve for C:
C = 6[tex]\pi[/tex]
C = 18.8
So, the circumference of the fountain is approximately 18.8 feet
