24/48 is half. Anything less than 24 would be less than half.
Answer:
Yes.
Step-by-step explanation:
Half of 2 is 1, so 1/2 means half.
Half of 48 is 24, so 24/48 is also half.
23/48 is less than 24/48, so 23/48 is less than 1/2.

A circle with a center at (5,-2) also has the point (8,2) that lies on the circle. What is the equation of the circle?
Answer:
Step-by-step explanation:
You get the center just by reading the given point.
(x - 5)^2 + (x + 2)^2 = r^2 Notice that the center switches signs.
(8,2) is given so that you can figure out the radius.
The radius uses the distance formula to get from (5,-2) to (8,2)
x1 = 5
x2 = 8
y1 = -2
y2 = 2
==================
formula
d^2 = (x1 - x2)^2 + (y1 - y2)^2
solution
d^2 = (5 - 8)^2 + (-2 - 2)^2
d^2 = (-3)^2 + (-4)^2
d^2 = 9 + 16
d^2 = 25
==================
Answer
(x - 5)^2 + (y + 2)^2 = 25

the speed of a new microprocessor is 800mhz but a new test of its speed gives a measurement of 820mhz. what is the abolute error? what is the relative error?
The answers are:
[tex]AbsoluteError=20mhz[/tex]
[tex]RelativeError=2.5(Percent)[/tex]
Why?To solve the problem we need to remember that the absolute error is the difference between the expected value and the measured value, also, to calculate the relative error we first need to calculate the absolute error, and then, divide it by the expected measure.
So, calculating we have:
[tex]AbsoluteError=Expected-MeasuredValue\\\\AbsoluteError=800mhz-820mhz=-20mhz[/tex]
We can see that we obtained a negative value, however, when we are working with "absolute" values, the negative symbol is discarded, so, we have that:
[tex]AbsoluteError=20mhz[/tex]
Now, to calculate the relative error, we need to use the following formula:
[tex]RelativeError=\frac{AbsoluteError}{ExpectedValue}*100\\\\RelativeError=\frac{20}{800}*100=0.025*100=2.5(Percent)[/tex]
So, we have that the relative error is equal to 2.5%.
Hence, we have that:
[tex]AbsoluteError=20mhz[/tex]
[tex]RelativeError=2.5(Percent)[/tex]
Have a nice day!
Absolute error is 20 MHz and relative error is 2.5%.
Absolute error: Absolute error is the difference between the measured value and the actual value. In this case, the absolute error is 820 MHz - 800 MHz = 20 MHz.
Relative error: Relative error is the ratio of the absolute error to the actual value. The relative error can be calculated as (820 MHz - 800 MHz) / 800 MHz = 0.025 or 2.5%.

The slope of the line below is 2. Which of the following is the point-slope form
of the line?
(1,-1)
A. Y+1 = -2(x - 1)
B. y-1 = 2(x+1)
c. y-1 =-2(x+1)
D. y+ 1 = 2(x-1)
Answer:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
Suppose an airplane climbs 15 feet up for every 40 feet it moves forward. What is the slope of this airplanes ascent?
The slope of the airplane's ascent is calculated using the rise over run formula and is 3 / 8 or 0.375.
Explanation:
The slope of the airplane's ascent can be calculated by the ratio of the rise over the run. In this case, the airplane climbs 15 feet up (rise) for every 40 feet it moves forward (run). Therefore, using the formula slope = rise / run, we can determine that the slope of the airplane's ascent is 15 / 40, which simplifies to 3 / 8 or 0.375.

y = 4x + 5 and 2y = 8x + 10
y = 4x + 5 and y =
x+5
y = 4x + 5 and y = 8x + 10
Answer:
y = 4x + 5 and y = 4x - 5Step-by-step explanation:
(1) y = 4x + 5 and (2) y = 4x - 5
substitute (1) to (2):
4x + 5 = 4x - 5 subtract 4x from both sides
5 = -5 FALSE (no solution)
(1) y = 4x + 5 and (2) 2y = 8x + 10
substitute (1) to (2):
2(4x + 5) = 8x + 10 divide both sides by 2
4x + 5 = 4x + 5 subtract 4x from both sides
5 = 5 TRUE (infinitely many solutions)
(1) y = 4x + 5 and (2) y = x + 5
substitute (1) to (2):
4x + 5 = x + 5 subtract 5 from both sides
4x = x subtract x from both sides
3x = 0 divide both sides by 3
x = 0
Put it to (2):
y = 0 + 5 = 5
One solution (0, 5)
(1) y = 4x + 5 and (2) y = 8x + 10
substitute (1) to (2):
4x + 5 = 8x + 10 subtract 5 from both sides
4x = 8x + 5 subtract 8x from both sides
-4x = 5 divide both sides by (-4)
x = -1.25
Put it to (1):
y = 4(-1.25) + 5 = -5 + 5 = 0
One solution (-1.25, 0)
What is the slope of the line?
A) –2
B) –[tex]\frac{1}{2}[/tex]
C) [tex]\frac{1}{2}[/tex]
D) 2
Your answer is B) -1/2
One way of finding this answer is by using the slope equation (y2 - y1)/(x2 - x1) and substituting in the coordinates on the line. This gets you
(2 - 3)/(4 - 2) = -1/2
Another way is to find the slope by looking at the graph, and seeing that it must be negative because it slopes downwards to the right instead of up, and that it must be 1/2 because for every 1 unit you go down, you go 2 across, which means your y/x is 1/2.

which Inequality represents all possible solutions of -12d≥ -6? A.d≤ -1/2 B.d ≥ -1/2 C.d≤ 1/2 D.d≥1/2
Answer:
D. d ≥ 1/2.
Step-by-step explanation:
-12d ≥ -6
d ≥ -6/-12
d ≥ 1/2.
The Inequality represents all possible solutions of -12 d ≥ (-6) is d ≤ 1/2.
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We have the inequality,
-12 d ≥ (-6).
Now, solving the inequality
Divide both side by 12
(-12 d )/ 12 ≥ (-6)/ 12
-d ≥ -1/2
Now, multiply both side by (-1), we get
d ≤ 1/2.

When a nursery owner orders plants from the distributor, 92% of the plants arrive alive. If the nursery owner wants their inventory of a particular plant to be 540 living plants, how many plants should the owner order?
You must make a [tex]\frac{part}{whole}[/tex] proportion.
92% is part of 100%
540 would need to be the 92% of the plant bought. That means 540 is the part and the whole would be the unknown (let's make this x)
Set up your proportion like so...
[tex]\frac{540}{x} =\frac{92}{100}[/tex]
Cross multiply...
92x = 540 * 100
92x = 54000
Isolate x by dividing 92 to both sides...
92x/92 = 54000/92
x = 586.9565
Since you can't buy a decimal of a plant you will have to round this number up to the next whole number...
587
To have 540 of the plants arrive alive the nursery owner must order 587 plants

Is g(x)= 5x-1 an odd function
Answer:
No
Step-by-step explanation:
g(x)= 5x-1 is the same as g(x)= 5x^1 - 1x^0, which contains one odd power (x^1) and one even power (x^0). Therefore, g(x)= 5x-1 is neither even nor odd.

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
Answer:
The inequality would be 4x + 9 ≥ 0
Step-by-step explanation:
You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.
For this case we have a function of the form [tex]y = f (x)[/tex], where:
[tex]f (x) = \sqrt {4x + 9} +2[/tex]
We must look for the domain of the function. By definition, the domain of a function is given by all the values for which the function is defined.
So, for the given function to be defined, the argument of the root must be positive, that is:

If 2p+q=11 and p+2q=13, then p+q =
Answer:
the desired result is (p + q) = (3 + 5) = 8
Step-by-step explanation:
Let's solve this system of linear equations in the usual way: find the values of p and q. Then find (p + q) as a numerical result.
Solve:
2p+q=11
p+2q=13
Multiply the second equation by -2:
2p + q = 11
-2p - 4q = -26
Combining these two equations results in -3q = -15, and so q must be 5.
Subbing 5 for q in the first equation, we get:
2p + 5 = 11, or 2p = 6. Then p = 3.
Then the desired result is (p + q) = (3 + 5) = 8
The required answer is p + q is equal to 8 by solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.
To find the value of p + q, we can use the given system of equations:
Equation 1: 2p + q = 11
Equation 2: p + 2q = 13
We can solve this system of equations by either the substitution method or the elimination method. Let's use the elimination method:
Multiply Equation 1 by 2:
2(2p + q) = 2(11)
4p + 2q = 22 ...(Equation 3)
Subtract Equation 2 from Equation 3:
(4p + 2q) - (p + 2q) = 22 - 13
4p + 2q - p - 2q = 9
3p = 9
Divide both sides by 3 to solve for p:
p = 9 / 3
p = 3
Now substitute the value of p back into Equation 1:
2(3) + q = 11
6 + q = 11
Subtract 6 from both sides to solve for q:
q = 11 - 6
q = 5
Finally, we can find p + q:
p + q = 3 + 5
p + q = 8
Therefore, p + q is equal to 8 solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.
