Answer:
-2
Step-by-step explanation:
g(2) = 5*2-7 = 3
f(g(2)) = f(3) = 3^2 - 3*3 - 2
= 9-9-2
= -2
The actual length of the dust termite observed under the microscope is 1.5 mm
- The scale of image produced under the microscope 100 : 1
- This means image is magnified 100 times its original size as microscopes are used to enlarge or magnify the size objects.
- Taking the measured size of the dust termite under the microscope in millimeter = 150 mm
The actual length of the termite will be :
- Measured size under microscope ÷ 100
Therefore, the actual length of the dust termite is about 1.5 mm

Answer:
31.25 percent increase
Step-by-step explanation:
To find the percent increase, we take
percent increase = (new - original)/new * 100 percent
= (420-320)/320 * 100 percent
100/320 * 100 percent
.3125 * 100 percent
31.25 percent increase
Answer:
26.2 units
Step-by-step explanation:
We are given the points/vertices
A(6, 3),
B(6, - 2) , and
C(- 4, 3)
Step two
Let us find the distances between the given points/vertices
A-B =A(6, 3) to B(6,-2)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6-6)²+(-2-3)²)
d=√(-2-3)²)
d=√(-5)²)
d=5 units
B-C=B(6, - 2) to C(-4, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((-4-6)²+(3+2)²)
d=√(-10)²+(5)²)
d=√100+25
d=√125
d=11.2 units
C-A=C(-4, 3) to A(6, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6+4)²+(3-3)²)
d=√(10)²
d=√100
d=10 units
Hence the perimeter is 5+11.2+10
P=26.2 units
Hey There!
Expression- (13*2)+(3*2)=$32
This is the answer because Sam bought two cd's for 13, 13 *2, and the sales tax was $3, so 3*2=6.
