Answer:
1) the constant of variation is 1/6
2) b=80 when A=10
3)the value of k is 40
4) x=0.032 when y = 10
Step-by-step explanation:
1)m varies directly as y
k is the constant of variation
We are given that m is 6 when y is 36
Hence the constant of variation is 1/6
2)A varies directly as b.
k is the constant of variation
We are given that A = 3 when b = 24
Substitute A=10
80=b
So, b=80 when A=10
3)y varies inversely with x
k is the constant of variation
We are given that y = 5 when x = 8
So, the value of k is 40
4)y varies inversely with x
k is the constant of variation
We are given that k=0.32
Substitute y = 10
So, x=0.032 when y = 10
Answer:
c. 9 det A
Step-by-step explanation:
Given the following data;
Since A is a square matrix of order 2, we know that n = 2
K = 3
For any scalar k;
∣kA∣ = k^{n} ∣A∣
<em>Substituting into the equation;</em>
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
<em>Therefore, det (-3A) = 9 detA</em>
Answer:
(14,1)
Step-by-step explanation:
You can see with the LKMJ rectangle, it moves over 7 and up 3.
We can do this for STUV and U is originally (7,-2) but moves up and right to the point (14,1)
Answer:
204 inches
Step-by-step explanation:
First, change the 5yd2ft to be just feet.
1 yard = 3 feet
5 yd × 3ft/yd = 15 ft
15 ft + 2ft = 17ft
Next, change to inches.
1 ft = 12 inches
17ft × 12in/ft = 204 in
5 yds 2 ft = 204 in
