If A is a square matrix of order 2, then det(-3A) is *
a. 3 det A
b. -3 det A
c. 9 det A
d. -9 det A
Help please.
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∣
Substituting into the equation;
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
Therefore, det (-3A) = 9 detA
Richard invests $230.92 every month into his mortgage. At the end of 30 years, he has a balance of $184,033.06. What interest did he make over 30 years?
Richard made $100,719.46 in interest over 30 years on his mortgage.
To calculate the total interest Richard made over 30 years, we need to find the total amount he invested and then subtract that from the final balance.
Richard invests $230.92 every month for 30 years, which is a total of:
Total investment = 30 years * 12 months/year * $230.92/month
Total investment = $230.92 * 360
Total investment = $83,313.60
Now, we can calculate the interest earned by subtracting the total investment from the final balance:
Interest = Final balance - Total investment
Interest = $184,033.06 - $83,313.60
Interest = $100,719.46
Therefore, Richard made $100,719.46 in interest over 30 years on his mortgage.

3 folders cost $2.91 dollar sign . Which equation would help determine the cost of 2 folders? WRITE THE LETTER IN THE SPACE BELOW.
Answer:
$1.94
Step-by-step explanation:
Cost of 3 folders = $2.91
We need to find the cost of 2 folders.
First we will find the cost of 1 folder
1 folder = $2.91/3 = $0.97
To find the cost of 2 folders, multiply $0.97 and 2
2 folders = $0.97 × 2
= $1.94
Hence, the cost of 2 olders is $1.94.
Sally sold seashells by the seashore for 3 days for $2.45 per seashell. On the first day, she sold twice as many seashells as the second day, and on the second day, she sold four seashells less than she sold on the third day. If she sold 7 seashells on the third day, how much money did she make on those three days?
seashells less than she sold on the third day. If she sold 7 seashells on the third day, how
much money did she make on those thre
Step-by-step explanation:
1st day: 6 seashells, 14.7 dollars
2nd day: 3 seashells, 7.35 dollars
3rd day: 7 seashells, 17.15 dollars
All together: 39.2 dollars
day 3 = 7
day 2 = 7 - 4 = 3
day 1 = 3 * 2 = 6
total seas shells = 7 + 3 + 6 = 16
total money = 16 * 2.45 = $39.20

A triangle has vertices on a coordinate grid at P(-10,1)P(−10,1), Q(-10,-7)Q(−10,−7), and R(-5,-7).R(−5,−7). What is the length, in units, of \overline{PQ}
PQ
?
Answer:
Step-by-step explanation:
Given the following coordinates of a triangle
P(-10,1)
Q(-10,-7)
R(-5,-7)
Required
Length of PQ
PQ = √(y2-y1)²+(x2-x1)²
From the coordinate;
x1 = -10, y1 = 1, x2 = -10 y2 = -7
Substitute
PQ = √(-7-1)²+(-10-(-10))²
PQ = √(-8)²+0²
PQ = √64
PQ = 8units
Hence the length of PQ in units is 8units

what number makes the equation true
Answer: the answer is -2 1/3
Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3
The number that makes the equation
[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex] true is [tex]\rm \bold {-2\dfrac{1}{3} }[/tex].
So option 4 is correct.
Let the number that makes equation true is x
The question is that what makes equation true
[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]
This equation is a linear expression with one variable and rational numbers.
This equation can be solved in the following way
[tex]\rm -5 +x = -\dfrac{22}{3} \\x = 5 -\dfrac{22}{3} \\x = (15-22)/3 \\x = -7/3\\ x= -2\dfrac{1}{3}[/tex]
So from the given options in figure we can see that option 4 is correct
