Answer:

How do you find the zeros of a polynomial graphically?

Step-by-step explanation:

If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.

Answer:

If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72

Answer:

No, it is a obtuse triangle instead

Step-by-step explanation:

So, you use pythagorean and theorem which is a^2 + b^2 = c^2

So when you plugin in the numbers, it's 20^2__ 12^2 + 12^2

When you square them you get left with 400__144 + 144

Then, you add 144 + 144 = 288

But since 400 is > than 288, then it's an obtuse triangle.

Answer:

No

Step-by-step explanation:

It does not follow the Pythagorean Theorem, which states that the two shorter sides squared (squared BEFORE added together).  12 squared is 144, and 144 plus 144 equals 288.  20, which seems to be the hypotenuse, squared is 400.  288 does not equal 400.

Answer:

It takes Sanjay 40 minutes and Zion 120 minutes

Step-by-step explanation:

If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes

Painting together, they spent 30 minutes

1/x + 1/3x = 1/30

4/3x = 1/30

4 * 30 = 3x * 1

120 = 3x

x = 120/3

x = 40 minutes

3x = 3 * 40 = 120 minutes

..

Answer:

k can either be

12

or

−

12

.

Step-by-step explanation:

Consider the equation

0=x2+4x+4

. We can solve this by factoring as a perfect square trinomial, so

0=(x+2)2→x=−2 and−2

. Hence, there will be two identical solutions.

The discriminant of the quadratic equation (b2−4ac) can be used to determine the number and the type of solutions. Since a quadratic equations roots are in fact its x intercepts, and a perfect square trinomial will have

2 equal, or 1

distinct solution, the vertex lies on the x axis. We can set the discriminant to 0 and solve:

k2−(4×1×36)=0

k2−144=0

(k+12)(k−12)=0

k=±12

Answer:

The answer is (2+7)*2

Step-by-step explanation:

as you can see the you have to add the bottom to the top then multiply the answer by the height to what i did was i seen if there was anything that can add to 7 with the number 2 and 5 was so put 5 at the top and multiply 7 times two you get 14  

9514 1404 393

Answer:

Step-by-step explanation:

If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...

  3x +2y = 520

  2x -y = 20

__

These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:

  (3x +2y) +2(2x -y) = (520) +2(20)

  7x = 560 . . . . simplify

  x = 80 . . . . . . divide by 7

  y = 2x -20 = 2(80) -20 = 140

The cost of a lamp is $80; the cost of an end table is $140.

Answer:

The answer is D

Step-by-step explanation:

Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary

This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.

You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other

Q

Step-by-step explanation:

Answer: Q, it's the only horizontal line

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]

AKA SohCahToa.

To find the height, we will use sine.

[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]

To find the length we will use cosine.

[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

Answer: 1, it’s a continuous cuz it’s a line and not dots

Answer:

0.090401

Step-by-step explanation:

Given that:

Probability of graduate = 81% = 0.81

P( not graduate) = p = (1 - 0.81) = 0.19

1 - p = 0.81

Using binomial distribution :

P(x = x) = nCx * p^x * 1-p^(n-x)

n = 15 ; x =5

P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)

P(x = 5) = 15C5 * 0.19^5 * 0.81^10

P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801

P(x = 5) = 0.090401

Answer:

D:   (15/5) (0.19)^5 (0.81)^10

Step-by-step explanation:

Answer: Let's solve for x.

2x−10y=10

Step 1: Add 10y to both sides.

2x−10y+10y=10+10y

2x=10y+10

Step 2: Divide both sides by 2.

2x

2

=

10y+10

    x=5y+5

Step-by-step explanation:

Let's solve for s.

sx+9y=9

Step 1: Add -9y to both sides.

sx+9y+−9y=9+−9y

sx=−9y+9

Step 2: Divide both sides by x.

sx

Answer:

the first one and last one are true

Step-by-step explanation:

Answer:

The required numbers are:

First number = 4

Second number = 0

Step-by-step explanation:

Let First number = x

second number = y

We are given:

One number is four more than a second number.

Writing in mathematical form:

[tex]x=y+4[/tex]

Two times the first number is 8 more than four times the second

Writing in mathematical form:

[tex]2x=4y+8[/tex]

Now, we will solve these equations by substitution to find values of x and y

Let:

[tex]x=y+4--eq(1)\\2x=4y+8--eq(2)[/tex]

Now, putting value of x from eq(1) into eq(2)

[tex]2x=4y+8\\Put\:x= y+4\\2(y+4)=4y+8\\2y+8=4y+8\\2y-4y=8-8\\-2y=0\\y=0[/tex]

So, we get y=0

Now put value of y in equation 1 to get value of x

[tex]x=y+4\\x=0+4\\x=4[/tex]

So, we get x=4

So, the required numbers are:

First number = 4

Second number = 0
