Answer:
c.3 got a 100
Step-by-step explanation:
Answer:
z=12
Step-by-step explanation:
It is given that x varies jointly as y and z, it means



where, k is the constant of proportionality.
It is given that x=8 when y=4 and z=9


Divide both sides by 36.


The value of k is 2/9.

We need to find the value of z when x=16 and y=6.
Substitute x=16 and y=6 in the above equation.


Multiply both sides by 3.

Divide both sides by 4.

Therefore, the value of z is 12.
ANSWER
A) v1 is not perpendicular to v2
EXPLANATION
Two non-zero vectors are orthogonal or perpendicular if their dot product is zero.
In other words,if two non-zero vectors are not orthogonal or perpendicular then their dot product is not equal to zero.
From the question v1 and v2 are non-zero vectors and their dot product is not equal to zero.
This tells us that, the two vectors are not perpendicular.
The correct choice is A.
Answer:
see explanation
Step-by-step explanation:
the arc length of a circle is calculated as
arc = circumference of circle × fraction of circle
(5)
circumference (C) is calculated as
C = 2πr ( r is the radius )
here diameter = 12 , then r = 12 ÷ 2 = 6
C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )
(6)
JK = 2πr × 
= 2π × 7 × 
= 14π × 
=
≈ 9.2 in ( to the nearest tenth )
(7)
7.5 = 2πr ×
7.5 = 2πr ×
( multiply both sides by 3 to clear the fraction )
22.5 = 2πr ( divide both sides by 2π )
r =
≈ 3.6 ft
Answer:
$1912.27
Step-by-step explanation:
Simple interest rate formula: A = P(1 + r)^t
Simply plug in the known variables
A = 1700(1 + 0.04)³
A = 1700(1.04)³
A = 1700(1.12486)
A = 1912.27
