This is equivalent to:

(2.2533/2.59)(10^8/10^4)

(0.87)(10^4) which is:

0.87X10^4 which is equal to:

0.87X10000 which is equal to:

8.7X1000 and since 1000=10^3 we can say:

8.7X10^3

In 3-8, find the missing side length of each right triangle. 50yd. 30yd.

denis23 [38]

Hi! so you didn’t let us know which side length is missing and it kind of matters so i’ll attach an image so you can just copy the one that looks most like yours.

What are the solutions of the equation x6 – 9x3 + 8 = 0? Use u substitution to solve. x = –1 and x = –2 x = 1 and x = 2

malfutka [58]

Let u=x^3
the original equation becomes: u^2-9u+8=0
factor this quadratic equation: (u-8)(u-1)=0
u=8, or u=1
that means x^3=8 or x^3=1
x=2 x=1

How do I calculate this? Is there a formula?

Answer:

Height of cables = 23.75 meters

Step-by-step explanation:

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of $x = 600$ or $x = -600$ , and y at 95.

We know that the equation of a parabola is in the form $y=ax^2$ and here it passes through the point $(600, 95)$ .

$y=ax^2$

$95=a \times 600^2$

$a=\frac{95}{360000}$

$a=\frac{19}{72000}$

So new equation for parabola would be $y=\frac{19x^2}{72000}$ .

Now we have to find the height $(y)$ of the cable when $x= 300$ .

$y=\frac{19 (300)^2}{72000}$

y = 23.75 meters

Daniel made 6 out of 15 free throw shots. About how many out of the next 10 free throw shots would you expect him to make

mixer [17]

6÷15= 0.4= his percentage at the line
0.4×100%= 40%
(x represents how much he makes in 10 shots) x/10 = 40/100 (Percent from the line)
cross multiply 100x=400
isolate x
100x÷100= 400÷100
x=4
I predict that daniel will make 4 shots out of ten
