Answer:
A = 192 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 12, b₁ = AB = 14 and b₂ = DC = 2 + 14 + 2 = 18, then
A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 18) = 6 × 32 = 192 in²

x=10
Step-by-step explanation:
6^2+8^2=x^2
36+64=x^2
100=x^2
x=10
Answer:
10
Step-by-step explanation:
The pythagorean theorem states that a^2+b^2=c^2. a and b are the shorter sides and c is the hypotenuse, or the longest side. You can tell the hypotenuse because it is opposite to the right angle.
Therefore, a=6, b=8 and c=x. You can switch a and b if you like, it doesn't really matter.
using the pythagorean thm. 6^2+8^2=x^2. You simplify the exponents and combine like terms to get x^2=100. You take the square root of both sides and get 10.

Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)

Find the values of x and y.
help please work has to be shown ..
Answers
Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

why do systems of nonlinear equations sometimes have more than one solution
Answers
Answer:
System has equal number of unknowns and equations.
Manipulation easily yielded expressions for 4 of the 7 unknowns.
However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.
Is this possible, or did I most probably make a mistake in counting degrees of freedom?

Answers
Answer:
752 ft
Step-by-step explanation:
Assuming t represents time, and the time we are trying to find is how high the rockets go after 1.5 seconds, we must take the equation and put 1.5 in wherever t occurs, this looks like:
-16(1.5)²+64(1.5)+80
solving this, we get:
-24²+96+80
576+96+80

questions below

Find the slope of the line shown on the graph to the right (-4,-3) and (2,3)
Answers
Answer:
y=x+1
Step-by-step explanation:
to do this we have to use the slope formula, Rise/Run which is (y2-y1)/(x2-x1) so (3-(-3) or 3+3 divided by (2-(-4) or 2+4, so the slope would be 6/6 or 1. so it is up one over one, and since at the x coordinate of 0 it is y=1 we know the formula must be y=x+1
Answer:
m = 1
Step-by-step explanation:
Use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex] to find the slope.
next, the equation should look like: [tex]y=\frac{3+3}{2+4}[/tex]
Next you should get the equation: [tex]m = \frac{6}{6}[/tex]
Finally, just divide 6/6 and the answer will be m = 1
