Step-by-step explanation:

Graph of the Quadratic Function

We are given the function:

[tex]y=f(x)=-x^2+8x-15[/tex]

Select 5 values of x={2,3,4,5,6}

And calculate the corresponding values of y:

[tex]f(2)=-2^2+8*2-15=-4+16-15=-3[/tex]

[tex]f(3)=-3^2+8*3-15=-9+24-15=0[/tex]

[tex]f(4)=-4^2+8*4-15=-16+32-15=1[/tex]

[tex]f(5)=-5^2+8*5-15=-25+40-15=0[/tex]

[tex]f(6)=-6^2+8*6-15=-36+48-15=-3[/tex]

We have obtained the points

(2,-3) (3,0) (4,1) (5,0) (6,-3)

Now we plot them in the graph below.

It can be noted three remarkable points:

The roots of the equation

Answer:

Step-by-step explanation:

Add the equations together and solve for x.

[tex](2x + y )+ (3x - y) = 11 + 4[/tex]

[tex]5x=15[/tex]

[tex]x=3[/tex]

Use equation [tex]2x+y=11[/tex]  to solve for y.

[tex]2(3) +y=11[/tex]

[tex]6+y=11[/tex]

[tex]y=11-6[/tex]

[tex]y=5[/tex]

Answer:

The correct options for the possible lengths of the third side are;

13 inches

28 inches

Step-by-step explanation:

The given lengths of two sides of the triangle are;

The length of one side of the triangle = 1 foot = 12 inches

The length of the other side of the triangle = 20 inches

The question can be solved by the triangle inequality theorem as follows;

A + B > C

B + C > A

A + C > B

Let the given sides be A = 12 inches and B = 20 inches

We have;

12 + 20 = 32 > C

Therefore, by the triangle inequality theorem, the third side, 'C', is less than 32 inches

Similarly, when C = 6 inches, we have;

A + C = 12 + 6 = 18 < B = 20

Therefore, the third side cannot be 6 inches

when C = 13 inches, we have;

A + C = 12 + 13 = 25 > B = 20

Therefore, the third side can be 13 inches

when C = 28 inches, we have;

A + C = 12 + 28 = 30 > B = 20

Therefore, the third side can be 28 inches

Based on the triangle inequality theorem, the possible lengths of the third side of the triangle are: 13 inches and 28 inches.

The Triangle Inequality Theorem

The triangle inequality theorem states that, sum of the length of any two sides of a given triangle = length of the third side.

Given the measures,

The possible third side must make the three set of numbers conform to the triangle inequality theorem.

Thus, for 13 inches, we have:

13 + 12 > 20; 12 + 20 > 13; 20 + 13 > 12

Also, for 28 inches, we have:

28 + 12 > 20; 12 + 20 > 28; 20 + 28 > 12

Therefore, based on the triangle inequality theorem, the possible lengths of the third side of the triangle are: 13 inches and 28 inches.

Answer:

lets say you needed to find the greates comon factor of 20 and 5, you need to find the closest number they both go into, so 20. or if it was 3 and 10 it would be 30 because it is the closest thing they both go into, i hope i am right i am so sorry if i am wrong.

A)

   a

———=8       :a=64

5+3  

Steps:Multiply both sides by 8

     ———-=8  ·   8

      5+3

B)

3b/7 - 1 = 5

Add 1 in both sides

3b/7 - 1 + 1 = 5 + 1

3b/7 = 6

Multiply both sides by 7 and then divide by 3.

3b/7 . 7/3 = 6 . 7/3

b = 2.7

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

[tex]s=\dfrac{48}{b}[/tex]

Hence, the required expression is (48/b).

Answer:

let

a=9cm

b=8cm

c=10cm

Step-by-step explanation:

now

s=(a+b+c)/2=(9+8+10)/2=13.5

area of traingle=√(s(s-a)(s-b)(s-c))=√(13.5(13.5-9)(13.5-8)(13.5-10))=34.197cm²

Answer:

-88

Step-by-step explanation:

If a=2, we can say that -[tex]a^{2}[/tex] would be -4.

Secondly, if a=2 and b=-6 we can assume that 4ab would become -48.

Finally, if b=-6 we can say that -[tex]b^{2}[/tex] would become -36.

Adding all of those up gives you -88, your answer.

Answer:

cosC = 30/50

Step-by-step explanation:

Before you find cosC, you should know that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

You should also know that trigonometric ratios work for only right triangles.

If cosine = adjacent side/hypotenuse, then:

cosC = 30/50

cosC = 0.6

If rounding to the nearest four decimals, it should be 0.6000.
