The graph of a certain quadratic function has no x-intercepts. Which of the
following are possible values for the discriminant? Check all that apply.
A. 25
B. -18
C. -4
D. 0

Answer:

w = 20

Step-by-step explanation:

Add 18 on both sides:

[tex]\frac{w}{4} =5[/tex]

Multiply by 4 on both sides:

w = 20

Answer:

20

Step-by-step explanation:

Let's solve your equation step-by-step.

−13=−18+ w/ 4

Step 1: Simplify both sides of the equation.

−13=−18+ w/ 4

−13=−18+ 1/ 4 w

−13= 1/ 4 w−18

Step 2: Flip the equation.

1/ 4 w−18=−13

Step 3: Add 18 to both sides.

1/ 4 w−18+18=−13+18

1/ 4 w=5

Step 4: Multiply both sides by 4.

4*( 1/ 4 w)=(4)*(5)

w=20

Step-by-step explanation:

The annual net income on the rental property is the yearly rental minus the yearly annual expenses which consist mortgage interest,taxes, repairs,insurance as well as annual depreciation totaling $8,750

Annual rental =monthly rental* 12 months=$960*12=$ 11,520.00  

Annual net income=$ 11,520.00-$8,750.00=$2,770

Answer:

54 π cubic centimeters

Step-by-step explanation:

Formula for the volume of a cylinder: πr²h

π×3²×6=

9×6×π=

54π cm³

Answer:

2.4 cm

Step-by-step explanation:

The formula we would use

S = rθ

Where S = Arc length

θ = central angle in radians

r = radius of the circle or length of the radius.

From the question, we can see that if

If C = a point on circle A

The Segment BC = The arc length of the circle = 12cm

∠BAC = central angle in radians = 5 radians.

Since, S = rθ,

Length of the radius = S/θ

= 12cm/5 radians

Length of the radius = 2.4 cm

First, we need to find the radius, which is the distance between the given points.

[tex]d=\sqrt{(3-5)^{2} +(10-2)^{2} } =\sqrt{4+64}=\sqrt{68}[/tex]

Therefore, the radius of the circle is

Answer:

It will take 1.19 seconds for the ball to hit the ground if no other players touch it

Step-by-step explanation:

The height of the ball after t seconds is given by the following equation:

[tex]h(t) = -4.9t^{2} + 5t + 1[/tex]

How long will it take the ball to hit the ground if no other players touch it?

This is t when h(t) = 0. So

[tex]-4.9t^{2} + 5t + 1 = 0[/tex]

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

In this question:

[tex]-4.9t^{2} + 5t + 1 = 0[/tex]

So [tex]a = -4.9, b = 5, c = 1[/tex]

So

[tex]\bigtriangleup = 5^{2} - 4*4.9*1 = 44.6[/tex]

[tex]t_{1} = \frac{-5 + \sqrt{44.6}}{2*(-4.9)} = -0.17[/tex]

[tex]t_{2} = \frac{-5 - \sqrt{44.6}{2*(-4.9)}  = 1.19[/tex]

Since we want a time measure, the answer cannot be negative.

It will take 1.19 seconds for the ball to hit the ground if no other players touch it

Answer:

Average monthly interest = $ 122.04

% total interest =36.94 %

Step-by-step explanation:

There are 120 cumulative payments and the total interest paid was $ 14,644.95.

Hence, the average monthly interest is :

Average monthly interest = $ 14,644.95 / 120

Average monthly interest = $ 122.04

% total interest

= ($ 14,644.95) / $ 39,644.95 x 100

Step-by-step explanation:

The greatest common factor GCF of 9 and 14 is 1.

Given the numbers in the question:

9 and 14

To find the greatest common factor of two numbers, we need to identify all the factors of each number and then determine the greatest number they have in common.

First:

Factors of 9 are 1, 3, and 9, as these are the whole numbers that divide 9 without leaving a remainder.

Next,

Factors of 14 are 1, 2, 7, and 14, as these are the whole numbers that divide 14 without leaving a remainder.

The common factors of 9 and 14 are 1 since it is the only number that divides both 9 and 14.

Therefore, the greatest common factor of 9 and 14 is 1.

Answer:

0.45.

Step-by-step explanation:

To find the solution to this question, we will first need to determine how many cards are neither Cincinnati Reds and Cleveland Indians. We can do this by:

100 - 22 - 33 = 45. This is the number of cards that are neither the two teams.

To convert this to a decimal, simply divide by 100, giving us:

45 ÷ 100 = 0.45.

Answer:

See explanation below

Step-by-step explanation:

In this case, I'm assuming you want to know the price of all items purchased by Andrea.

Let's gather all the data.

Andrea has initially 54$. From that she got a Brush (B), a sketchbook (S) and a paint set (P). At the end, she has a left over of 1.5$, so she actually spends 52.5$, and our first equation would be:

B + S + P = 52.5  (1)

Now, the B cost 1/6 as the S, and S was 3/4 the paint set, so oru equations here would be:

B = 1/6S (2)

S = 3/4P (3)

Now, according to this we can write the (1) expression in function of (2) and (3).

Replacing (3) in (2):

B = 1/6 (3/4P)

B = 3/24P

B = 1/8P  (4)

And replacing (3) and(4) in (1) we have:

1/8P + 3/4P + P = 52.5

From here we can solve for P:

15/8P = 52.5

P = 52.5 * 8 / 15

P = 28.16$

Now we can replace this value to get the Sketchbook, and then, the brush:

S = 3/4 * 28.16

S = 21.12$

B = 1/6 * 21.12

B = 3.52$

These values would be the price of all items.

Step-by-step explanation:

The length of fringe Sharon needs to purchase is: 16 feet

If Sharon gets a new bedsheet of 1.25 feet longer, she will need a new length of fringe of: 18.5 feet

Recall:

Perimeter of a rectangular = 2(length + width)

Given the following:

The length of fringe Sharon will need to purchase = perimeter of Sharon's rectangular bedspread

Perimeter = 2(3 + 5) = 16 feet

For a new bedspread that is 1.25 feet longer, she would get the following length of fringe:

Length = 3 + 1.25 = 4.25 feet

Width = 5 feet

New Perimeter = 2(4.25 + 5) = 18.5 feet

Answer:

John will need 34 more tickets to be able to go on all the rides he wants

Step-by-step explanation:

To solve this, we need to first of all know the total cost in terms of tickets of all the rides that john wants to have.

This will be

cost of roller coaster ride = 19 tickets

cost of bumper car ride = 3 tickets

cost of merry-go-round ride = 33 tickets

Total cost of rides = 19 + 3 + 33 =55 tickets

Next, we will need to find the number of tickets that John has left after losing 10 of them.

This will be 31 - 10 = 21 tickets left

To find the number of more tickets that John needs , we will subtract the number of tickets he has left from total ride ticket cost.

This will be 55-21 = 34 tickets.

Hence, John will need 34 more tickets to be able to go on all the rides he wants

Step-by-step explanation:

On the unit circle, [tex]-\pi=\pi[/tex]. The sin of theta is therefore 0, the cosine is -1, and the tangent is 0/-1=0.

I have attached a unit circle diagram.

In this unit circle corresponding values of sine and cosine have been written near the angle 'α' in form (cosα,sinα)

x-coordinate is cosα

y-coordinate is sinα

now,

one can find other trigonometric ratios

[tex]tan\alpha =\frac{sin\alpha }{cos\alpha } \\\\cot\alpha =\frac{1}{tan\alpha } \\\\cosec\alpha =\frac{1}{sin\alpha } \\\\sec\alpha =\frac{1}{cos} \\[/tex]

Answer:

100:59

Step-by-step explanation:

For every pound a company spends on advertising, it spends £0.59 on its website.

Amount Spent on Advertising = £1

Amount Spent on Website = £0.59

Therefore:

Amount Spent on Advertising : Amount Spent on Website

= 1 : 0.59

Multiply both sides by 100

= 100: 59

The ratio of the amount spent on advertising to its website as a ratio in its simplest form is 100:59 in its simplest form.

Answer:

£100 : £59

Step-by-step explanation:

The said company spends £0.59 on its website for every pound spent on advertisement. This implies that out of £1.00 spent on advertisement by the company, £0.59 is for website placements.

Thus, the rate of the amount spent on advertisement to amount spent on website is given as:

             £1.00 : £0.59

To convert this to the nearest whole number, multiply through by 100, so that the ratio becomes;

£100.00 : £59.00

Therefore, the ratio expressed in its simplest form is £100 : £59
