PLS HELP ASAP What is the value of x?

Furkat [3]

ANSWER

a. 12 units

EXPLANATION

According to the altitude theorem, RT which is the altitude, is equal to the geometric mean of TQ and TS, the segments created by the foot of the altitude on the hypotenuse.

This implies that:

$x = \sqrt{TQ \times TS}$

From the diagram, TQ=16 and TS=9.

We substitute these values and solve for x.

$x = \sqrt{9 \times 16}$

$x = \sqrt{144}$

$x = 12$

Therefore x is 12 units.

The correct answer is A

In 2014, a town's population was 795 people. By 2020, the population had grown to 1262 people. a. Create an exponential equation

Zina [86]

Answer: $P=795(1.84)^n$

Step-by-step explanation:

Given

Initial population was $795$ people

By 2020, it becomes $1262$ people

Suppose the population follows the trend $P=P_oa^{n}$

where, $n$ is the number of years after 2014

For year 2020 it is 6. Insert the values

$\Rightarrow 1262=795a^{6}\\\\\Rightarrow 1.587=a^{6}\\\\\text{Taking log both sides}\\\\\Rightarrow \log (1.587)=6\log (a)\\\Rightarrow \log (a)=0.2645\\\\\Rightarrow a=10^{0.2645}\\\Rightarrow a=1.84$

Thus, the exponential population trend is $P=795(1.84)^n$
