harkovskaia [24]

I believe this question is missing an image. However, I will just tell how how to solve such question and you can apply this solution to the triangle you have.

In any given triangle, the sum of the measure of the three angles must be equal to 180 degrees.
Therefore, for a triangle pqr:
measure angle pqr + measure angle prq + measure angle rqp = 180 degrees

If you have one angle given, then the sum of the other two angles will be equal to 180 - measure of the given angle.

If you have two angles given, then the measure of the third angle will be equal to 180 - the sum of the other two angles.

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the

Lelu [443]

Answer:

The reasonable domain to plot the growth function is the interval [0,9]

$0\ days\leq d\leq 9\ days$

Step-by-step explanation:

In this problem we have a exponential function of the form

$f(d)=a(b^d)$

where

f(d) is the radius of the algae in mm

d is the number of days

a is the initial value or y-intercept

b is the base

r is the rate of growth

b=1+r

we have

$a=9\ mm\\b=1.04\\r=1.04-1=0.04=4\%$

we have

$f(d)=9(1.04^d)$

For f(d)=12.81 mm

substitute in the function and solve for d

$12.81=9(1.04^d)$

$(12.81/9)=(1.04^d)$

Apply log both sides

$log(12.81/9)=log(1.04^d)$

$log(12.81/9)=(d)log(1.04)$

$d=log(12.81/9)/log(1.04)$

$d=9\ days$

therefore

The reasonable domain to plot the growth function is the interval [0,9]

$0\ days\leq d\leq 9\ days$

IRISSAK [1]

Answer:

Step-by-step explanation:

1.

The supplementary angles to ∠x are adding to 180° and are ∠HGC and ∠BGA

2.

If ∠DGE = 90° , then

∠CGD is also 90° because ∠DGE and ∠CGD are a linear pair and

∠HGC is also 90° because ∠DGE and ∠HGC are vertical angles

Zach bought a gold necklace originally priced at $50 but on sale for 60% off. After 10% sales tax,

Flura [38]

Answer: $22

Step-by-step explanation:

First we calculate for the sale price.

We have to find how much is 60% of 50.

We do this by:

$50 *0.6=\\$

This equals 30.

We now subtract the 30 from the 50 to get our sale price.

$50 -30 =$

The sale price is $20.

Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.

$1+0.1$

This equals 1.1

This is what we will multiply the $20 by.

$20*1.1=\\$

The total cost is $22.
