Step-by-step explanation:
X^2-2=2(x^2+4x-5)-(x-4)(x-4)
X^2-2=2(x^2+4x-5)-(x^2-8x+16)
X^2-2=2x^2+8x-10-x^2+8x-16
2x^2-x^2-x^2+8x+8x-10-16+2=0
16x-24=0
16x=24
X=2
We have an equation and we know the values of the variables p, r, and t.
Plug in the values.
I = (8000)(0.6)(1)
I = 4800
So, I is equal to 4800.
Answer:
d=2√2, b=
Step-by-step explanation:
first triangle is a 30-60-90
so, sides x-x√2-2x
x=2
therefore d=2√2
second triangle is 45-45-60
sides, 1-1-√2
which means b√2=6
b=6/√2 ---> multiply by √2/√2 to get ride of the √2 denominator
b=6√2/4 , simplify
b=
Answer:
A=259.43
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r=R/100
r=2.5/100
r=0.025 rate per year,
then solve the equation for A
A=P(1+r/n)
A=250.00(1+0.025/1)
A=250.00(1+0.025)
A=$259.43
Answer: The area of the cross section is 2 cm^2.
If I am understanding your problem correctly, we are just looking for the area of the grey rectangle, which is the cross section.
The length and width of this gray rectangle are already given to us. The are 1 and 2. Just multiply them to get the area.
1 x 2 = 2 cm^2
