Question ❓:-<br>4^(x+2)+2^(2x+1)-36=0,x=?

sergiy2304 [10]

Answer:

x = 1/2

Step-by-step explanation:

$4^{x+2}+2^{2x+1}-36=0$
$16*4^x+2*2^{2x}-36=0$
$16*4^x+2*4^x-36=0$
$18*4^x = 36\\\\$
$4^x=2\\\\$
$2^{2x}=2^1\\$
$2x=1\\$
$x = 1/2$

Giselle has a catering business. There is a proportional

Vanyuwa [196]

Answer:

1) The graph labeled and the ordered pairs plotted are shown in the second picture.

2) To calculate the amount of meat (in pounds) needed for a party of 75 people:

Substitute the value of the Constant of proportionality and $x=75$ into the equation $y=kx$ and then evaluate (The result is 30 pounds).

Step-by-step explanation:

<h3> The missing graph is attached.</h3>

Proportional relationships have the following form:

$y=kx$

Where "k" is the Constant of proportionality.

1) You can observe in the graph shown in the first picture this point:

$(10,4)$

So you can subsitute the coordinates of this point into $y=kx$ and solve for "k":

$4=k(10)\\\\k=\frac{4}{10}\\\\k=\frac{2}{5}$

Now you can find the amount of meat needed for 20, 30, 40, and 50 people with this procedure:

<u>For 20 people</u>

Substituting $k=\frac{2}{5}$ and $x=20$ into the equation $y=kx$ and evaluating, you get:

$y=(\frac{2}{5})(20)=8$

The ordered pair is:

$(20,8)$

<u>For 30 people</u>

Substituting $k=\frac{2}{5}$ and $x=30$ into the equation $y=kx$ and evaluating, you get:

$y=(\frac{2}{5})(30)=12$

The ordered pair is:

$(30,12)$

<u>For 40 people</u>

Substituting $k=\frac{2}{5}$ and $x=40$ into the equation $y=kx$ and evaluating, you get:

$y=(\frac{2}{5})(40)=16$

The ordered pair is:

$(40,16)$

<u>For 50 people</u>

Substituting $k=\frac{2}{5}$ and $x=50$ into the equation $y=kx$ and evaluating, you get:

$y=(\frac{2}{5})(50)=20$

The ordered pair is:

$(50,20)$

Knowing those values of "y"and having the ordered pairs, you can finish labeling the graph an plotting the ordered pairs (See the second picture.).

2) Substituting $k=\frac{2}{5}$ and $x=75$ into the equation $y=kx$ and evaluating, you can calculate the amount of meat (in pounds) needed for a party of 75 people. This is:

$y=(\frac{2}{5})(75)=30$

Volume & surface! May I please have help

Ludmilka [50]

Answer:

D

Step-by-step explanation:

surface area of cylinder

=(area of base)×2 + (area of curved surface)

$=(\frac{20}{2} )^{2} \pi$ × 2 + $20\pi$ × 25

=2 × $\pi$ × $10^{2}$ + 2 × $\pi$ × 10 × 25

For hockey practice, Rosa has to skate around a face off circle five times. The face off circle has a diameter of 9.0m. About ho

SVETLANKA909090 [29]

Answer:

$Distance\ cover\ by\ Rosa = 141.3\ m$

Step-by-step explanation:

Given:

Rosa has to skate around a face off circle five times.

$Distance = 5\times circumfrance\ of\ circle$

Diameter of a circle = 9.0 m

Radius of a circle = $\frac{d}{2} =\frac{9}{2}=4.5\ m$

Solution:

We know that the circumference of a circle.

$C = 2\pi r$

Where;

r = Radius of a circle

Substitute $\pi =3.14\ and\ r = 4.5$ in above equation.

$C = 2\times 3.14\times 4.5$

$C = 28.26\ m$

So, the circumference of the circle is 28.26 m.

Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.

$Distance\ cover\ by\ Rosa = 5\times 28.26$

$Distance\ cover\ by\ Rosa = 141.3\ m$

Therefore, the distance cover by Rosa to skate 141.3 m.
