Ummmm 5.6 I'm pretty sure equals 89.6 forgive me if I'm wrong
The cable should be 50 feet.
If you draw the picture, you will see that you have a right triangle.
Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).
30^2 + 40^2 = c^2
2500 = c^2
50 = c
Answer:
#1 is 31°
#2 is 120°
Step-by-step explanation:
You know that a triangle is 180°. In the first one its a right triangle, which means that angle is 90°. Subtract 90 and 59 by 180. The second subtract 36 and 24 by 180 to get your answer.
Answer: Y = 4, X=4 (4,4)
Step-by-step explanation: You must multiply both equations so the leading coefficient cancels out. I’m multiplying both equations by both coefficients so I multiply the entire first equation by -2 so the first equation will be the negative coefficient and the second equation will be multiplied by positive 9 so the negative and positive equations cancel out.
STEPS IN MATH:
1. (9x-8y=4) -2 = -18x + 16y = -8
(2x-3y=-4)9 = 18x-27y= -36
2. ADD THESE EQUATIONS TOGETHER NOW
-18x+16y=-8
+ 18x-27y=-36
0-11y= -44
-11y=-44
DIVIDE -44 by -11y
The final answer is Y= 4
NOW pick an equation to plug in y to, any equation works
I chose the first one, so 9x-8(4)=4
9x-32=4
9x=36
x=4
Answer:
There are an infinite number of points on that graph.
Step-by-step explanation:
To find any of them, simply input a value for x and simplify to find y.
For this example, we'll use x = 4
f(x) = 4x
f(x) = 4(4)
f(x) = 16
So we could find (4, 16) on the graph
