Answer:

$x=\ln{y}$

Step-by-step explanation:

The natural logarithm function is the inverse of the natural exponential function.

$\text{power}=\text{base}^{\text{exponent}}\\\\\text{exponent} \: =\: \log_\text{base}{\text{power}$

are equivalent.

A triangle has side lengths of (6.2p + 4.5q) meters, (3.4p – 0.7r) meters, and (2.9r – 4.1q) meters. Which expression represents

Natalija [7]

Answer:

9.6p + 0.4q + 2.2r meters (answer A)

Step-by-step explanation:

We sum up the three side lengths to obtain the perimeter of the triangle:

(6.2p + 4.5q) meters, , and (2.9r – 4.1q) meters

+ (3.4p – 0.7r) meters

+ (2.9r – 4.1q) meters

---------------------------------

9.6p + 0.4q + 2.2r meters (answer A)

Answer:

use a calculator itl be easy

Step-by-step explanation:

substitute x to 150

=0.00125(x)^4+x-3

=0.00125(150)^4+150-3

WE ARE USING PEDMAS HERE SO BE CARE-FULL <u>parenthesis,exponent,multiplication,division,addition,subtraction</u>

<u>=0.00125(506250000)+150-3</u>

<u>=632812.50+150-3</u>

=<u>632962.50-3</u>

=<u>632959.50</u>

Which is an equation of a circle with center (5, 0) that passes through the point (1, 1)

alex41 [277]

Equation of circle at center (h,k) is given by

$(x-h)^2+(y-k)^2=r^2$

Given that center is at (5,0) that means h=5 and k=0

plug both values into above formula

$(x-5)^2+(y-0)^2=r^2$

$(x-5)^2+y^2=r^2$ ...(i)

Given that circle passes through point (1,1) so it will satisfy above equation

$(1-5)^2+1^2=r^2$

$(-4)^2+1^2=r^2$

$16+1=r^2$

$17=r^2$

Now plug this value of r^2 into equation (i)

$(x-5)^2+y^2=17$

which best matches with choice C

Hence $(x-5)^2+y^2=17$ is the final answer.
