Answer:

Second option

$x =9$

Step-by-step explanation:

To solve this problem we use the secant theorem.

If two secant lines intersect with a circumference, the product between the segment external to the circumference and the total segment in one of the secant lines is equal to the product of the corresponding segments in the other secant line.

This means that

$(5+4)*4 = (x+3)*3$

Now we solve the equation for the variable x

$(9)*4 = (x+3)*3$

$36 = 3x + 9$

$36-9 = 3x$

$3x =27$

$x =9$

The height of the tunnel at the center is 35ft, and the vertical clearance must be 21 ft at a point of 8ft from the center. Find

Zinaida [17]

Answer:

y=-0.215x^2+35

Step by Step:

Let, $h=0$ , $k=35$ , $x=8$ , $y=21$

We know that, the general equation of the parabola.

$y-k = a(x-h)^2$

$\Rightarrow y=a(x-h)^2+k .........(i)$

Substitute the value of $h, k, x, y$ in equation $(i)$ and find the value of $a.$

$21=a(8-0)^2+35$

$\Rightarrow 21=a\times 8^2+35$

$\Rightarrow 21=64a+35$

$\Rightarrow 64a=21-35$

$\Rightarrow 64a=-14$

$\Rightarrow a=\frac{-14}{65}$

$\Rightarrow a=-0.215$

Hence, the equation of the parabola is:

$y=-0.215x^2+35$

The energy released by metabolism of 1 average candy bar is 1 x 10^6 joules.

Elis [28]

Answer: 32

Step-by-step explanation:

Given: The energy needed for 1 hour of running for an adult $=4.5\times10^6\ joules.$

Therefore. the energy needed for seven hours of running= $=7\times4.5\times10^6\ joules.=31.5\times10^6\ joules$

Since, he energy released by metabolism of 1 average candy bar $=1\times10^6\ joules.$

Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.= $\frac{31.5\times10^6}{1\times10^6}=31.5\approx32$

Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.
