QUESTION POSTED AT 14/12/2019 - 05:10 PM

Answered by admin AT 14/12/2019 - 05:10 PM

The first question:

'is' in mathematics means equal
'of' in mathematics means multiplication

\frac{x}{100} \times 25 = 14\\\\\frac{x}{4} = 14\\\\\boxed{\bf{x=56}}

56% of 25 is 14.

And the second question:

'is' in mathematics means equal
'of' in mathematics means multiplication

\frac{x}{100} \times 20 = 11\\\\\frac{x}{5} = 11\\\\\boxed{\bf{x = 55}}

55% of 20 is 11.

And finally, the third question:

'is' in mathematics means equal
'of' in mathematics means multiplication

15 = \frac{x}{100} \times 5\\\\15 = \frac{x}{20}\\\\\boxed{\bf{x=300}}

15 is 300% of 5.

Which function below has the smallest slope? A Graph with a line going through -5 on the Y Axis and Postive 2 and a half on the X axis. f(x) f(x) = 2x - 3 h(x) x h(x) -1 3 1 7 3 11

For the first line:
m = (-5 - 0) / (0 - 2.5) = 2

For the second line:
From the given equation,
m = 2

For the third, using the given coordinates (-1,3) (1,7)
m = (7 - 3) / (1 - (-1)) = 2

Therefore, all the slopes of the lines are 2 and none of them have the smallest slope compared to the others.

What is the axis of symmetry for the function? y = x2 + 3x - 4 y = -2 x = -2 x = -1.5 y = -1.5 What is the vertex for the function? y = x2 - 4x - 3 (-1, 2) (0, -3) (1, -6) (2, -7) The vertex of y = 9 - 8x - x2 is (-4, 25) False True

Axis of symmetry is a line passing through the vertex which divides the curge into two parts such tha each part looks the same.
For y= x^{2} +3x-4, the 'x' part is squared and the coefficient of x^{2} is positive. Hence, the curve will be a parabola facing up which means that the axis of symmetry will be a vertical line. i.e. x = m.
Investigating, f(-1) == (-1)^{2} +3(-1)-4=1-3-4=-6
f(-1.5) = = (-1.5)^{2} +3(-1.5)-4=2.25-4.5-4=-6.25
f(-2) = = (-2)^{2} +3(-2)-4=4-6-4=-6
From these, the curve has a vertex at point (-1.5, -6)
Therefore the axis of symmetry is line x = -1.5 (i.e. the third option)

What will the last payment be to pay off a $1,250 computer plus 8% sales tax with monthly payments of $120? $10 $11 $12 $20 $30

The last payment would be $30. This is computed by solving first the total amount of computer including 8% tax, so 1,250 times 8% is equal to 100, then 100 plus 1,250 is 1,350. Then 1,350 will be divided by 120, which is equal to 11.25. Getting the 0.25, from 11.25, multiply be 120 (0.25 times 120), is equal to $30.

Total number of times cube was rolled = 100.
Total number of times a 6 was rolled = 27.
Probability of rolling a 6 =  \frac{27}{100}
Total number of times coin was tossed = 100.
Total number of times a head was tossed = 41.
Probability of tossing a head =  \frac{41}{100}
Therefore, probability of rolling a 6 and tossing a head =  \frac{27}{100}\times\frac{41}{100}=\frac{1107}{10000}

Add any three numbers of the following and answer should be 60? (2 , 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58)

Answer:

This is not possible.

Step-by-step explanation:

The given series is : 2 , 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58

Now, adding any three numbers to get 60, is not possible.

The numbers are in the form 2+4n where n is a positive integer.

Summing together three such numbers you get 6+4N

(N = n1 + n2 + n3, ...)

We want to get 6+4N= 60

=> 4N =54

=> n1+n2+n3 =27.5

Hence, it is not possible.

The first thing you have to take into account is the definition of the axis in the complex plane.

We have then:

The vertical axis represents the imaginary part.

The horizontal axis represents the real part.

We then have the following number:

-14 - 5i

Since the real part and the imaginary part are negative, then the number is located in the third quadrant of the complex plane.

Answer:

Quadrant III.

#1
Factoring the function:

f(x) = x3 + 7x2 + 14x + 8
f(x) = (x + 4) (x + 1) (x + 2)

From the options, (x + 2) is the factor

#2
f(x) / g(x) = (
6x3 - 19x2 + 16x - 4) / (x - 2)
This can be solved by factoring the numerator, by synthetic division or using the remainder theorem.

The result is:
6x^2 - 7x + 2 or (x - 2/3)(x - 1/2)
 
#3 same with #2

#4
(x3 - 5x2 + 2x + 5) / (x - 2)
Again, this can be solved by a number of methods, the result is:
x2 -3x - 4 - (3/x-2)

To prepare for a triathlon, Amanda starts from position A and rides her bike along a straight road for 12 miles to reach position B. At B, she turns left and rides along another straight road for 15 miles to reach position C. At C, she turns left again and rides 20 miles along a straight road to return to A. In ΔABC, what are m∠A, m∠B, and m∠C, respectively?

The angles can solved by using the cosine law. Solving for the measure of angle A
15² = 20² + 12² - 2(20)(12) cos A
A = 48.35°

Angle B can solved by either also using the cosine law or by sine law. Let's use sine law:
20 / sin B = 15 / sin 48.35
B = 85.06°

The measure of angle C can just be solved by difference of the total angle of the triangle.
C = 180 - 48.35 - 85.06
C = 45.59°

Answer:

A) Price= 1617*Year - 3.116e+006;     B) 150340$ By 2020

Step-by-step explanation:

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006  

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$

The best answer to the problem given above would be letter A. The speed of the skater travels at 10 miles per hour constantly. I got this through employing the formula, y2 - y1 / x2 - x1 and computed using the points.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)
v = 10 miles per hour

Thus, the answer is 10 miles per hour.

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots? A.The expression is 3p. It takes 30 minutes to shape and fire 10 pots. B.The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots. C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots. D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answer:

D. The expression is 3p+10. It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take 3p minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots = 3p+10

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = 3\times 10+10 = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.
