Answer:
-2x+3
Step-by-step explanation:
Gradient is change in y over change in x
=2
and then
+3 because that's where it cuts the Y axis
You have added -13 to every function value, so every point on the graph is 13 "spaces" lower. The y-intercept is one such point, so ...
-The y-intercept is 13 spaces lower.

<em>Comment on notation</em>
In plain text an exponent is preceded by a caret (^). If the exponent has arithmetic involved (addition, subtraction, multiplication, division), then the entire exponent needs to be enclosed in parentheses. When an exponential term that has a constant base is multiplied by another constant, then some sort of multiplication indicator is useful. Your expressions might be written ...
... f(x) = 4·2^x
... f(x) = 4·2^x - 13 . . . . . . or, better, f(x) = 4(2^x) - 13 . . so it is clear -13 is not part of the exponent

Question:
Find the area of the shaded segment. Round your answer to the nearest square centimeter.
a) 24 cm²
b) 23 cm²
c) 21 cm²
d) 22 cm²
Answer:
d) 22 cm²
Step-by-step explanation:
We have Area and a Triangle in that diagram.
In other to find the shades segment , we have to find the Area of the triangle and the Area of the sector
Step 1
Area of a Triangle
= 1/2 × a × b × sin θ
Where θ = 120°
a = 6 cm
b = 6 cm
Area of the triangle = 1/2 × 6 × 6 × sin 120°
= 15.59 cm²
Step 2
Area of the sector
The formula is given as
Area = πr²θ/360
r = radius = 6cm
Area = π × 6² × 120/ 360
Area = 37.699111843cm²
Approximately = 37.70 cm²
Step 3
The Area of the shaded segment = Area of the sector - Area of the triangle
= 37.70cm² - 15.59cm²
= 22.11 cm²
Approximately to the nearest square centimeter
= 22 cm²
Answer:
Step-by-step explanation:
2Y^5 . Y^3
it means 2Y^5 X Y^3
ans=2Y^8
