Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
Answer:
The correct option is D.
Step-by-step explanation:
The given graph is the graph of a cosine function, which shifts 1 unit left.
The cosine function is defined as
Where, a is amplitude, b is frequency, c is phase shift and d is vertical shift.
If c>0, then the graph shifts c units left and if c<0, then the graph shifts c units right.
Since the graph show only phase shift and the graph shifts only one unit left, therefore required function is
Option D is correct.
The patio is 22 feet long.
The act of measuring is the practice of comparing a physical quantity with a recognized standard quantity of a like kind. A base unit, sometimes called a fundamental unit, is a unit used to quantify a base amount. A base quantity is a physical quantity that is part of a traditionally selected subset of physical quantities but cannot be stated in terms of the other physical values in the subset.
Given the scale used is 1cm which represents 5.5 feet.
measure of patio on scale drawing is 4cm.
then it's length is 5.5 × 4 = 22 feet
These measurements pertain to the following: length, mass, time, electric current, temperature, amount of a substance, and luminance. Here are the seven base units' definitions: Distance: meters (m) Metric length is measured in meters.
hence we get the value of the length of the patio as 22 feet.

Let's create an equation to find the # of weeks until Chad learns 937 pieces.
x = # of weeks
937 = 2x + 805
Subtract 805 from both sides.
132 = 2x
Divide both sides by 2
66 = x
Chad will need 66 weeks of lessons to learn 937 pieces.
