Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
Answer:
Step-by-step explanation:
Need to find the value of t, when h(t) = 0
-
-16t^2 +64t + 100 = 0
- 4t^2 - 16t - 25 = 0
- 4t^2 - 2*2t*4 + 16 = 41
- (2t - 4)^2 = 41
- 2t - 4 = √41
- 2t - 4 = 6.4
- 2t = 10.4
- t = 5.2
Answer is 5.2 seconds
Answer:
The value of y given the values of x and z in the question is -734.85
Step-by-step explanation:
This is a joint variation question.
First, we are made to know that y varies jointly as x and z.
The equation for this can be written as;
y = k * x * z
Where k is the constant of proportionality.
Let’s calculate k first.
117 = k * (-3) * (-11)
33k = 117
K = 117/33 = 3.55
Now, we proceed to get what y is when x = -9 and z = 23
Let’s plug these values into the initial equation written.
y = k * x * z
We use the value of k calculated above;
y = 3.55 * (-9) * (23) = -734.85
Are you sure this is college mathimatics bec this doesn't look like it
