Answer:
-1
Step-by-step explanation:
(-1)^1001
= (-1)^1000 * (-1)^1
Since -1 raise to the power of an even number gives a positive value, then;
(-1)^1000 = 1
(-1)^1000 * (-1)^1 = 1 * -1
(-1)^1000 * (-1)^1 = -1
Hence (-1)^1001 = -1
A line that models the data is given by the equation
y= 1.62x + 18 , where y represents the wait time,
and x represents the number of staff available.
The slope of the line is -1.62. What does this mean in
this situation?
Answer:
Kindly check explanation
Step-by-step explanation:
Give the line of best fit :
y = 1.62x + 18 ; where ;
y = wait time ; x = number of staffs available
If slope of the line is -1.62.
The slope of linear graph represents the ratio of change in the y variable and the x variable. With a slope value of - 1.62, the rate of change is negative and thus an increase in x will lead to a decrease in y. This means that for every unit increase in the number of staffs, the wait time reduces at a rate of 1.62 per unit.
Determina la pendiente y el ángulo de la recta tangente a la función f(x)=x2-8x+16 en el punto a(6,4)
Answer:
[tex]4[/tex]
[tex]75.96^{\circ}[/tex]
Step-by-step explanation:
La función es
[tex]f(x)=x^2-8x+16[/tex]
La derivada de la ecuación nos da la tangente
[tex]f'(x)=2x-8[/tex]
El punto es [tex](6,4)[/tex]
Entonces en [tex]x=6[/tex]
[tex]f'(6)=2\times 6-8=4[/tex]
La pendiente de la tangente es [tex]4[/tex].
El ángulo de la pendiente está dado por
[tex]\tan\theta=m\\\Rightarrow \theta=\tan{-1}m\\\Rightarrow \theta=\tan^{-1}4\\\Rightarrow \theta=75.96^{\circ}[/tex]
El ángulo que forma la tangente con el eje x positivo es [tex]75.96^{\circ}[/tex]
Let g(x) vertical shift of f(x)=-x up 3 units followed by a vertical stretch by a factor of 4. Write the rule for g(x).
Given:
g(x) vertical shift of [tex]f(x)=-x[/tex] up 3 units followed by a vertical stretch by a factor of 4.
To find:
The rule for g(x).
Solution:
We have,
[tex]f(x)=-x[/tex]
This function shifts 3 units up. So,
[tex]f(x)+3=-x+3[/tex]
This function vertical stretch by a factor of 4. So,
[tex]g(x)=4(f(x)+3)[/tex]
[tex]g(x)=4(-x+3)[/tex]
[tex]g(x)=-4x+12[/tex]
Therefore, the rule for g(x) is [tex]g(x)=-4x+12[/tex].
The expression 6a-14-a+7 simplifies to
4x + y = 24
y=-4x+24
Substitution
Step-by-step explanation:
4x -24=-y
-24-4x=y
then do calculation
Answer:
infinite solutions
Step-by-step explanation:
substitute y in the first equation
4x+(-4x+24)=24
4x and -4x cancel out
24/24=1
or solve for x, you should also get 1
therefore, infinite solutions. you can also try using a graphing calculator
An accountant gets paid $150 for each tax return she prepares and her goal is to earn $6,750 preparing tax returns during this tax season if she has already prepared three tax returns as taxis and how many more tax returns must be prepared in order to reach her goal
Answer: 42
Step-by-step explanation:
First you have to subtract 450 from 6750 to get 6300
Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450
Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.

Matt has 2/3 yard of fishing line. He uses 3/8 to make fishing knots. Shade the model to show the amount of line that Matt uses to make fishing knots?
Answer:
1/4 yards was to make fishing knot
Step-by-step explanation:
Given that :
Yards of fishing line = 2/3
Fraction used to make fishing knot = 3/8
Amount of yards used to make fishing knot;
3/8 of the number of yards was used to make fishing knot.
(3/8) of 2/3)
(3/ 8) * (2 /3)
6 / 24
= 1 / 4 yards
here is a list of four fractions 1/16 2/8 15/60 3/9
one of these are not equivalent to 1/4
write down this fraction
Answer:
3/9
Step-by-step explanation:
15*4= 60 so 15/60 is equivalent to 1/4.
1/16 is just a smaller equivalent of 2/8 which is just a smaller equivaent of 1/4.
3/9 simplified is 1/3. I/s is bigger than 1/4.
Hope this helps
Answer:
3/9
Step-by-step explanation:
[tex]\frac{1}{4}\cdot\frac{4}{4}=\frac{4}{16}\\\\\frac{1}{4}\cdot\frac{2}{2}=\frac{2}{8}\\\\\frac{1}{4}\cdot\frac{15}{15}=\frac{15}{60}[/tex]
We can turn 1/4 into all of the first three fractions by multiplying it by some version of 1, but we can't do the same for 3/9: trying to multiply 1/4 by 3/3 will get us a different fraction: 3/12. Additionally, 3/9 in lowest form is 1/3, and 1/3 is clearly not equal to 1/4.

The answer will be 1/10. First you will change the denominator to the same number because you can’t mutiply fractions if the denominator is different. 5x2=10 and 2x5=10. So both of the denominator will turn into a 10. Now you’ll have to find the numerator. For the first one, multiply it by 2 because that how much the number need to turn equalvilant for the denominator. 1x2=2. So now you know that the first fraction is 2/10. Then you multiply 1 with 5 which is 5. Now the numbers all have the same denominator. Multiply 2/10 and 5/10 which is 1/10.

Determine the geometric mean of 45 and 15
The solution is, The geometric mean of 45 and 15 is 25.98.
What is geometric mean?The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.
here, we have,
We are given two numbers as 45 and 15.
Formula for geometric mean is
G.M = √x₁ × ... × xₐ
So, using this we get
⇒G.M = √45 × 15
⇒G.M = √675
⇒G.M = 25.98
Hence, the geometric mean of 45 and 15 is 25.98.

Answer:
The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.
Step-by-step explanation:
The complete statement is:
Find [tex]\alpha_{2}[/tex] and [tex]r_{2}[/tex] such that [tex]\sin \theta - \sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos (\theta - \alpha_{2})[/tex].
We proceed to use the following trigonometric identity:
[tex]\cos (\theta - \alpha_{2}) = \cos \theta \cdot \cos \alpha_{2} +\sin \theta \cdot \sin \alpha_{2}[/tex] (1)
[tex]\sin \theta -\sqrt{3}\cdot \cos \theta = r_{2}\cdot \cos \theta \cdot \cos \alpha_{2}+r_{2}\cdot \sin \theta \cdot \sin \alpha_{2}[/tex]
By direct comparison we derive these expressions:
[tex]r_{2}\cdot \sin \alpha_{2} = 1[/tex] (2)
[tex]r_{2}\cdot \cos \alpha_{2} = -\sqrt{3}[/tex] (3)
By dividing (2) by (3), we have the following formula:
[tex]\tan \alpha_{2} = -\frac{1}{\sqrt{3}}[/tex]
[tex]\tan \alpha_{2} = -\frac{\sqrt{3}}{3}[/tex]
The tangent function is negative at second and fourth quadrants. That is:
[tex]\alpha_{2} = \tan^{-1} \left(-\frac{\sqrt{3}}{3} \right)[/tex]
There are at least two solutions:
[tex]\alpha_{2,1} = 150^{\circ}[/tex], [tex]\alpha_{2,2} = 330^{\circ}[/tex]
And the value of [tex]r_{2}[/tex]:
[tex]r_{2}^{2}\cdot \sin^{2}\alpha_{2} + r_{2}^{2}\cdot \cos^{2}\alpha_{2} = 4[/tex]
[tex]r_{2}^{2} = 4[/tex]
[tex]r_{2} = 2[/tex]
The values of [tex]r_{2}[/tex] and [tex]\alpha_{2}[/tex] are 2 and 150º.

Solve the right triangle. Round your answers to the nearest tenth place.
Answer:
for ac I got 11
ab i got 14
I'm not quite sure tho
but you could use SOH CAH TOA to find ab then use Pythagoras theorem to find AB
Answer:
AB = 11.6 inches
AC = 7.3 inches
m∠B = 39°
Step-by-step explanation:
To calculate side AB (c) put b (9 inches) over the sine of β (51°).
c = 9/sin(51)
The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse). This would be about 0.777.
c = 9/0.777
I recommend using a fraction here. 0.777 becomes 777/1000. Find the reciprocal (1000/777). Switch the sign to multiplication.
c = 9/1 * 1000/777
Cross cancel if needed.
c = 3/1 * 1000/259
Now multiply.
c = 3000/259
Divide 3000 by 259.
c ≈ 11.5830116 inches ≈ 11.6 inches
Now we know AB. To find AC, find the square root of AB² - BC².
AC = √(11.6² - 9²)
Square both 11.6 and 9.
AC = √(134.56 - 81)
Add 134.56 and 81 to get 53.56
AC = √53.56
Find the square root of 53.56
AC ≈ 7.31846979 ≈ 7.3 inches.

In office spends $375 per month on office supplies the manager wants the company to decrease office supply costs by 16% how much money would that save them each month
Answer:
$60
Step-by-step explanation:
The computation of the money saved each month is shown below:
= Spending per month × decrease office supply percentage
= $375 × 16%
= $60
The office supplies after given percentage is
= $375 - $60
= $315
So the money that saved each month is $60
7 = 3(5+X) X = _?_
Answer:
-8/3
Step-by-step explanation:
7=3(5+X) = 3(5=X)=7 3(5+x) divided by 3 is 7/3 5+x=7/3 5+x-5=7/3 -5 so x=-8/3
2) Find the missing measure. Show your work.
X =
130°
Answer:
The missing angle I believe is 25%.
Step-by-step explanation:
180-130=50
Divide 50 by 2 and it equals 25. 25 degrees for each angles.
Answer:25
Step-by-step explanation:
alright so the triangle theorem states that all of the angles of a triangle add up to 180. we already of 130 so we take away 130 from 180 to get 50. If you see the two little lines on the triangles sides opposite of the two angles that we are missing then you can tell by those lines that the angles opposite of them are equal to each other. So you divide 2 from 50 to get 25 which is the value of x. Hope you understand this (:
