It snowed 57.5 in Big Bear
Because 15% of 50 is 7.5 and 50+7.5=57.5
Hope this is helped
If you imagine a clock, the minute hand would've moved for 25% or 1/4 of the clock. So we need to find 1/4 of a circle in degrees
Because a circle is 360 degrees, we can do 1/4*360 which will get us 90°
Hope this helps
Move the decimal over 2 places to the left which will give you .419
The expression 4x^2-px-7 leaves a remainder of -2 when divided by (x-3). Then the value of p is 10.33
<h3><u>
Solution:</u></h3>
Given the expression is leaves a remainder of -2 when divided by (x-3)
To find: value of p
x - 3 = 0
x = 3
Let
Hence we can say,
g(3) = -2
Substitute x = 3 in g(x) we get,
On solving we get,
-2 = 4(9) - 3p - 7
-2 = 36 - 3p - 7
3p = 36 - 7 + 2
3p = 31
Thus the value of p is 10.33
The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
