Step-by-step explanation:
Answer is B.
Square root of 10 is 3.16.
3 and one fourth is 3.25.
3.12, 3.16, 3.24, 3.25
The fact that this triangle is a right angle triangle makes you now have 2 angles and the 1 side given, so it should be solvable.
First, You know that A=46 and C=90 as it is the right angle, and you know that the sum of any triangle's angles is 180. so now B=180-(90-46)=44
Now to the sides,
sin(B)=opp./hyp.=b/c=8/c=sin(44)
so, c=8/sin(44) which is approximately 11.52 unit length
now, use Pythagoras to find a,
a=√c²-b² =√11.52²-8² which is approximately 8.3 unit length.
Hope this helps.
Answer:
Step-by-step explanation:
The height of the marshmallow (in feet) is represented by the equation h=−16t2+8t+48,
where t is the time (in seconds) after he throws the marshmallow.
The equation is a quadratic equation. When the marshmallow hits the ground, its height from the ground will be zero. Therefore
−16t^2+8t+48 = 0
- 2t^2 + t + 6 = 0
Multiplying through by the negative sign. It becomes
2t^2 - t - 6 = 0
2t^2 + 3t - 4t - 6 = 0
t(2t + 3) - 2(2t + 3) = 0
(t - 2)(2t + 3) = 0
t - 2 = 0 or 2t + 3 = 0
t = 2 or t = - 3/2
The time cannot be negative
So it will take 2 seconds to hit the ground
The very rich
control the market and decide what industries to invest in or lend money too.
They influence the government so that they don't have to pay very much in
taxes, which would support the nation's infrastructure, & provide jobs. The
middle class works hard to produce products, and also spends money on products,
which helps to make the rich investors even more wealthy. The poor are typically
unable to compete in a capitalist economy (for a number of reasons), &
require public assistance to survive.
Answer:
h=5
Step-by-step explanation:
10+38h=200
-10 -10
38h=190
divide 38 from each side
h=5
