Answer:

-9

Step-by-step explanation:

One of the rules of exponents is that you can move something from the numerator to the denominator or from the denominator to the numerator as long as you change the sign of the exponent. So if there is a 5∧9 in the denominator of the fraction we can move it to the numerator as long as we make the exponent from a 9 to a -9

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Find the distance of (-7,-5) and (-3,4) round to the nearest tenth

Luba_88 [7]

Answer:

7.2 units

Step-by-step explanation:

Distance² = (Change in y)² + (Change in x)²

Distance² = (4 - -5)² + (-3 - -7)²

Distance² = 36 + 16

Distance² = 52

Distance = 7.211102551

Rounding off the answer to nearest tenth gives 7.2 units

At the start of the year, 15 chameleons were introduced into a zoo. The population of chameleons is expected to grow at a rate o

bearhunter [10]

Answer:

option-B

Step-by-step explanation:

We are given

At the start of the year, 15 chameleons were introduced into a zoo

so, $P_0=15$

The population of chameleons is expected to grow at a rate of 41.42% every year

so, r=0.4142

and x represents the number of years since the chameleons were introduced into the zoo

now, we can set equation to find total population

and we get

$P(x)=P_0(1+r)^x$

now, we can plug values

$P(x)=15(1+0.4142)^x$

$P(x)=15(1.4142)^x$

Average rate of change between 2 years and 4 years:

we can use formula

$A_1=\frac{P(4)-P(2)}{4-2}$

now, we can plug values

$A_1=\frac{15(1.4142)^{4}-15(1.4142)^{2}}{4-2}$

$A_1=14.99914$

Average rate of change between 4 years and 6 years:

we can use formula

$A_2=\frac{P(6)-P(4)}{6-4}$

now, we can plug values

$A_2=\frac{15(1.4142)^{6}-15(1.4142)^{4}}{6-4}$

$A_2=29.99770$

Average rate of change between 6 years and 8 years:

we can use formula

$A_3=\frac{P(8)-P(6)}{8-6}$

now, we can plug values

$A_3=\frac{15(1.4142)^{8}-15(1.4142)^{6}}{8-6}$

$A_3=59.99425$

now, we will check each options

option-A:

we can see that

$A_3-A_2=30$

So, this is FALSE

option-B:

$A_1=\frac{1}{2}A_2$

So, this is TRUE

option-C:

This is FALSE

option-D:

we got

$A_1=\frac{1}{2}A_2$

so, this is FALSE

Write the equation of a line that goes through (1.-7) and has a slope of -5.

jekas [21]

Line equation is
y - y1 = m * (x - x1)
y - (-7) = (-5) * ( x - 1)
y + 7 = -5x + 5
y + 5x + 2 = 0
