Step-by-step explanation:
8x2 + 16x + 3 = 0
a is 8 b is 16 c is 3
multiply 8 and 3 = 24
what 2 numbers when multiplied make 24 and when added make 16?
use quadratic formula
a is 8 b is 16 c is 3
x= (-b +- (√b^2-4ac))/2a
x= (-16 +- (√b^2-4(8)(3)))/2(8)
x= (-16 +- (√16^2-96))/16
x= (-16 +- (√256-96))/16
x= (-16 +- (√160))/16
x= (-16 +- (4√10))/16
x= -1 +- (√10/4)
split up the + and -
x= -1 - √10/4 = -0.209431
x= -1 + √10/4 = -1.79057
I think it would be
X= 101cos(222.2) =-74.82 or 74.82 tithe left.
I’m not sure.. hope it is right :)
To find the area of a rectangle, we multiply the Base by the Height. In this case the: Base = AB and Height = BC
So to get the area, we multiply AB by BC. (and we know that <em>BC = 5x+5/x+3</em> <em>and BC = [3x+9/2x-4)</em>
So we would do:
x
Note: When multiplying fractions together, we multiply the numerator by the numerator, and the denominator by the denominator.
For example x =
Answer: x =
= [<em>Note: </em><em>we are able to factorise some brackets to make the sum easier. For example we can factor out the 5 in (5x+5) to get: 5(x+1) ]</em>
Now lets simplify by multiplying the 5 and 3 together in the numerator:
=
If you notice, there is a (x+3) in numerator and the denominator. This means that we can cancel out the (x+3), to get the most simplified expression for the area:
=
Final Simplified Answer: which is the last option
Answer:
Step-by-step explanation:
<u>Shaded area is the difference in the areas of big and small circles.</u>
- Circle area formula: A = πr²
- A = π(5²) - π(3²) = π(25 - 9) = 16 π = 50.2654824574 ≈ 50.27cm²
Answer:
R= $1,133/100(7+1)
=234.86 RS.
Step-by-step explanation:
percentile rank is the percentage of scores that shall be equal to or less than a given value. The percentage falls within the range of 0 to 100. To find out the percentile rank, we used the formula:
R= P/100(N+1). Where R is the percentile rank, p is a percentile and N number of items.
Let for round trip airfare; the percentile is $1,133. And the number of days for the trip is 7.put these values in the formula, we have
R= $1,133/100(7+1)
=234.86 RS.
