The answer is -7 because :

a=1, b=1, c=2
Discriminant = b^2 - 4ac
= 1^2 - 4*1*2
= -7

calculate the height at 3 seconds given that the rocket travels 85 feet per second and starts on a launch pad 15 feet of the gro

Airida [17]

Answer:

The height of the rocket at 3 seconds is 270 feet

Step-by-step explanation:

To calculate the height of the rocket at 3 seconds,

First, we will determine the height the rocket has traveled in 3 seconds

The height traveled by the rocket is given by

Height (h) = Velocity (v) × Time (t)

From the question,

The rocket travels 85 feet per second, that is the velocity of the rocket is 85 feet per second,

Now,

v = 85 feet / second

t = 3 seconds

Hence,

Height (h) = 85 feet /second × 3 seconds

Height = 255 feet

∴ the rocket would have traveled 255 feet in 3 seconds,

But, the rocket starts on a launch pad 15 feet of the ground,

Then, the height of the rocket at 3 seconds is

255 feet + 15 feet = 270 feet.

Hence, the height of the rocket at 3 seconds is 270 feet

I need this to be specific and quick! 35 points!

D) these two figures are similar they don't look similar at first because the X'Z'Y' is more upwards. But they are congruent meaning they are similar or exactly the same almost. This basically tells me that I need to use translation.

E) I can use reflection to get XYZ into X'Y'Z' by reflecting it across the x-axis. I could also use translation and move it up 6 and then move it to the right.

C) The last one I could use is rotation and move it around around 45* or something close to the the other one.

Determine whether test point (-6,4) is a solution to the linear inequality x+y_<1

tamaranim1 [39]

$\bf \begin{array}{llll}
-6&,&4\\
\uparrow &&\uparrow \\
x&&y
\end{array}\qquad x+y\le 1\implies -6+4\le 1\implies -2\le 1$

now, is it true that -2 is lesser than 1? if it's true, is a solution, if is false, is not then

Answer:

$y = {e}^{3}$

Step-by-step explanation:

$f(x) = {e}^{3x} \\ \\ plug \: x = 1 \\ \\ f(1) = {e}^{3 \times 1} \\ \\ f(1) = {e}^{3} \\ \\ plug \: f(1) = y \\ \\ y = {e}^{3}$

Chris used 45 meters of fencing to enclose a circular garden. What is the approximate radius of the garden,rounded to the neares

kobusy [5.1K]

The length of the fencing corresponds to the length of the perimeter of the garden:
$p=45 m$
We also know that the perimeter of a circle is given by:
$p=2 \pi r$
where r is the radius of the circle.

Putting together the two equations, we have
$2 \pi r = 45$
from which we can find r, the radius of the garden:
$r= \frac{45}{2 \pi}= \frac{45}{2 \cdot 3.14}=7.17 m$
