What is "a" if B=
is a singular matrix
| 2
2 a
Answer:
The value of a=4
Step-by-step explanation:
Given the matrix
[tex]B=\begin{pmatrix}1\:&\:2\:\\ \:\:\:2\:&\:a\end{pmatrix}[/tex]
A matrix is singular if its determinent is zero.
so solving the matrix B by taking its determinant to get the value a
[tex]\det \begin{pmatrix}1&2\\ 2&a\end{pmatrix}=0[/tex]
as according to determinant formula
[tex]\det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}\:=\:ad-bc[/tex]
[tex]1\cdot \:a-2\cdot \:2=0[/tex]
[tex]a-4=0[/tex]
[tex]a=4[/tex]
Therefore, the value of a=4

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.

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

Step-by-step explanation:
The given function can also be seen as the equation of the line in slope-intercept form:
[tex]y=mx+b[/tex]
Where:
m is the slopeb is the y-interceptx and y are corresponding coordinate points that lie on the line (x,y)Since all the lines are parallel, they all have the same slope. All we need to do is find the one that has a y-intercept of 1. The y-intercept is where x=0.

What is the inverse of function f?
f(x)=64x^3-1
The inverse function of f(x) is:
[tex]g(x) = \sqrt[3]{(x +1)/64}[/tex]
How to find the inverse function?
Here we have the function:
[tex]f(x) = 64*x^3 -1[/tex]
We want to find the inverse, we will say that is of the form:
[tex]g(x) = \sqrt[3]{a*x + b}[/tex]
If we evaluate f(x) on g(x), we get:
[tex]f(g(x)) = 64*(\sqrt[3]{ax + b})^3 - 1\\ \\f(g(x)) = 64*(ax + b) - 1[/tex]
If these are inverses, that must be equal to x:
[tex]64*(ax + b) - 1 = x\\\\64*a*x + 64*b - 1 = x\\[/tex]
Then:
64*a = 1
a = 1/64
64*b - 1 = 0
b = 1/64
So the inverse function is:
[tex]g(x) = \sqrt[3]{(x +1)/64}[/tex]

66,722 Cincinnati residents over the age of 25 have a bachelor's degree or higher. What percentage of Cincinnati residents who are over the age of 25 have a bachelor's degree or higher
Answer:
we are missing some information, so I looked for a similar question and found the attached image:
Cincinnati's total population = 298,957 people
Cincinnati's population over age 25 = 193,638
I added all the people that were up to 24 years old and then subtract that number from 298,957 - 105,319 = 193,638
Percentage of Cincinnati residents over age 25 that have a bachelor's degree or higher = 66,722 / 193,638 = 0.3446 = 34.46%
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

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

The correct format of the question is

a. [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex]
b. [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex]
Answer:
(C).The solid ball of radius 5 centered at (0,0,0) with the interior of the solid ball of radius 1 centered at (0,0,0) removed.
Step-by-step explanation:
These are the equation of Spheres
In the equation [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex], when we will take square root of 25 we will get radius as 5 so the Sphere is varying from radius 1 to 5, Which will make it into a Solid sphere with the center at (0, 0, 0)
In the equation [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex] it is given that the sphere is less than
radius 5 units.
Also there will be no sphere with radius from 0 to 1 because the sphere is starting from radius 1 and increasing till radius 5.
Therefore, The sphere is a solid increasing from radius 1 to 5.
and another solid sphere is removed from inside with radius increasing from 0 to 1.
