What is the sum of the measures of the interior angles of a polygon QRST
A.)180
B.)360
C.)90
D.)720
Answers
Answer:
B
Step-by-step explanation:
The sum of the interior angles of a polygon is given by the formula s=180(n-2), where s is the sum and n is the number of sides.
In this case, the polygon has 4 sides, so we can sub n for 4.
This gives s=180(4-2) or s=180×2.
Solving this gives the result of s=360.
**This question involves interior angles of polygons, which you may wish to revise. I'm always happy to help!
Option B is correct, 360 degrees is the sum of the measures of the interior angles of a polygon QRST.
What is Polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
We have to find the sum of the measures of the interior angles of a polygon QRST
S=180(n-2) is the formula to find the sum of the interior angles of a polygon
Where s represents the sum of measures and n represents the number of sides
The polygon has 4 sides, so we can substitute n for 4.
Sum=180(4-2)
=180(2)
=360 degrees.
Hence, Option B is correct, 360 degrees is the sum of the measures of the interior angles of a polygon QRST.

Find (-4) for f(x) = 9(3)^x
A. -108
B. 1/3
C. -729
D. 1/9
Answers
Answer:
D
Step-by-step explanation:
9(3)^-4
3^2 × (3^-4)
in algebraic expression a^n × a^m = a^n+m
3^2+(-4)
3^-2
but 3^-2 = 1/3²
1/3²= 1/9
The option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]f(x)=9(3)^x\\\\\\x=-4\\\\\\f(-4)=9(3)^{-4}\\\\f(-4)=\frac{9}{(3)^4}\\\\f(-4)=\frac{9}{81}\\\\f(-4)=\frac{1}{9}[/tex]
Hence, the option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]

A candle is 6 tall after burning for one hour. After 3 h, it is 5. 5 tall. Write a linear equation to model the hh () of the candle after burning () h.
Answers
Answer:
h(t) = -0.25t + 6.25
Step-by-step explanation:
Given that :
Height of candle after burning for 1 hour = 6
Height of candle after burning for 3 hours = 5.5
The linear model to show the height ight of candle after burning for h hours :
The height change per hour of burn ; this is the slope ;
Change in height / Change in time ;
Time = 1 hour ; height = 6
Time = 3 hours ; height = 5.5
Slope = (5.5 - 6) / (3 - 1) = - 0.5 / 2 = - 0.25
This means candle height decreases ; - 0.25 ft per hour :
Based on the linear, slope, intercept equation ;
y = mx + c
Candle height, h
h(t) = mt + c
c = intercept, we can obtain this thus ;
Using the height at 1 hour and slope;
After an hour burn :
6 = - 0.25t + c
t = 1
6 = - 0.25(1) + c
6 = - 0.25+c
6+0.25 =, c
c = 6.25
Hence ; to calculate height, h after burn time &
h(t) = -0.25t + 6.25
