Answer:

D. y = 2x2 + 16x+11

Step-by-step explanation:

this is the correct answer, the person above me is incorrect!!

ap ex :)

The standard form of the equation y = 2x² + 16x 11. Then the correct option is D.

The equation of a quadratic function, of vertex (h, k), is given by:

y = a(x – h)² + k

where a is the leading coefficient.

The vertex form of the equation of a parabola is y = 2(x + 4)² – 21.

Expand the equation, we have

y = 2(x + 4)² – 21

y = 2(x² + 16 + 8x) – 21

y = 2x² + 32 + 16x – 21

y = 2x² + 16x 11

Then the correct option is D.

Answer:

8.25

Step-by-step explanation:

To solve, you need to create a system of equations.  You will need two variables since you have two numbers.  Create your equations based on the descriptions given in the problem.

The difference of two numbers is 4.

x - y = 4

The sum of the two number is -7.

x + y = -7

Your system of equations is

x - y = 4

x + y = -7

You can solve systems of equations through either substitution or elimination.  You will get the right answer either way.  I will use substitution since that is my preference.

Rearrange the first equation so that it is equal to x.

x - y = 4

x = 4 + y

Plug this x-value into the x in the second equation.  Solve for y.

x + y = -7

(4 + y) + y = -7

4 + 2y = -7

2y = -11

y = -11/2

Use the y-value to solve for x.  You can plug it into either equation and get the right answer.  I will use the first equation.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = -3/2

Now you have both of the numbers.  Multiply to find the product.

-11/2 × -3/2 = 33/4 = 8.25

The answer is 8.25.

D. 0

Step-by-step explanation:

discriminant = b^2 - 4ac = 3^2 - 4(1)(15) = 9 - 60 = -51

Since the discriminant is negative, this equation has no real solutions. Therefore, the graph does not intersect the x-axis.

Answer: D. 0

Answer:

Step-by-step explanation:

What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:

S = 3A + 7

Now we can sub in that value for S to the original equation:

If A + S = 111 and S = 3A + 7, then

A + 3A + 7 = 111 and

4A + 7 = 111 and

4A = 104 so

A = 26 and

S = 3(26) + 7 so

S = 85 miles.

Scott drove 85 miles.

Answer:

Scott drove 89.5 miles.

Step-by-step explanation:

Represent Andre's distance by a and Scott's by s.  Then s = 3a + 7.

Then the total distance driven by both is a + 3a + 7 = 117 (miles), or

4a - 110 miles, or a = 27.5 miles.  Thus, s = 3(27.5) + 7 = 89.5 miles.

Answer:

Step-by-step explanation:

We have 3 triangles here, all of them right triangles. The first one is the biggest one, triangle ABC. We know the side length AB = 14, and we know the hypotenuse length, BC = 30. We can use that, along with Pythagorean's Theorem, to solve for side length AC:

[tex]30^2=14^2+(AC)^2[/tex] and

[tex]900-196=(AC)^2[/tex] and

[tex]704=(AC)^2[/tex] so

[tex]AC=8\sqrt{11}[/tex]

We also have the smallest right triangle, triangle ABD, which has the base of x, our unknown. Side BD is our unknown, length x; side AD is the height, length y (also unknown); and side AB is the hypotenuse, length 14. We will come up with a system of equations for these 2 right triangles, using Pythagorean's Theorem, and then solve for x using substitution.

For the medium-sized triangle. triangle ADC, the hypotenuse is side AC with a measure of 8√11, the height is side AD length y, and the base is side DC length 30 - x. Putting those values into Pythagorean's Theorem:

[tex](30-x)^2+y^2=(8\sqrt{11})^2[/tex] and

[tex]900-60x+x^2+y^2=704[/tex] and

[tex]x^2-60x+y^2=-196[/tex]***  That's starred because it's important and we will come back to it.

The smallest triangle in Pythagorean's Theorem:

[tex]14^2=x^2+y^2[/tex] and solving that for y-squared:

[tex]y^2=196-x^2[/tex]. We will now sub that value for y-squared into the starred equation for y-squared and solve for x:

[tex]x^2-60x+196-x^2=-196[/tex] and

-60x = -392 so

x = 6.5

15.5833333333 or 15 7/12

Step-by-step explanation:

When you less simplify 1/4 and 1/3, we get 3/12 and 4/12. So, when you add those two fractions, you get 7/12. Now, we add 12 and 3 to get 15. Hence,

the two fractions given equal to 15 7/12.

Answer:111m^2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the function f(x)=(x+4)², the x intercept occurs at f(x)  = 0, substituting f(x) = 0 into the given equation to get the value of x we have;

[tex]0 = (x+4)^{2} \\[/tex]

Taking the square root of both sides

[tex]\sqrt{(x+4})^{2} = \sqrt{0}\\ x+4 = 0\\[/tex]

Subtracting 4 from both sides of the equation

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

Therefore the x intercept of the equation is -4

Answer:

The force pulling down the ramp is 374.6 lb

The force pressing on a line perpendicular to the ramp is 927.1 lb

Step-by-step explanation:

Given;

weight of boat (mg) , w = 1000 lb

angle of inclination of the ramp, θ = 22 degrees.

The force pulling the boat down, which is 'mg' has two components; the parallel component of the force which is pulling down the ramp and the vertical component of the force which is force pressing on a line perpendicular to the ramp

Parallel component of the force, F = mgsinθ

                                                      F = wsinθ

                                                      F = 1000 sin(22)

                                                      F = 1000 x 0.3746

                                                     F = 374.6 lb

Vertical component of the force which is force pressing on a line perpendicular to the ramp.

F = mgCosθ

F = wCosθ

F = 1000 x Cos(22)

F = 1000 x 0.9271

F = 927.1 lb

Step-by-step explanation:

Mathematically, the probability of drawing a pure cotton shirt = number of cotton shirts/Total number of shirts

Firstly , we are to calculate the number of cotton shirts after the addition of the new four

Thus;

Total number of shirts is now = 20+4 = 24

Let the number of cotton shirts be x after the addition

3/4 = x/24

24 * 3 = 4x

x = 72/4

x = 18

Now kindly recall that q became x only because we added 4 new extra cotton shirts

So the number of cotton shirts before the addition = 18-4 = 14

8 th term

Step-by-step explanation:

Continuing the sequence from the last term given (term 4 )

a₅ = 0.5 × 28.5 - 2 = 14.25 - 2 = 12.25

a₆ = 0.5 × 12.25 - 2 = 6.125 - 2 = 4.125

a₇ = 0.5 × 4.125 - 2 = 2.125

a₈ = 0.5 × 2.125 - 2 = 1.0625 - 2 = - 0.9375 ← negative

The first term to be negative is term 8

Answer:

Divide by two is the term to term rule

Step-by-step explanation:

64/2=32

32/2=16

16/2=8

8/2=4

the term-to-term rule for this sequence is to multiply each term by 1/2 to obtain the next term.

The given sequence 64, 32, 16, 8, 4 is a geometric sequence with a common ratio of 1/2.

To find the term-to-term rule for a geometric sequence, we multiply each term by the common ratio to get the next term. In this case, the common ratio is 1/2.

The term-to-term rule for this sequence is:

Multiply each term by 1/2 to get the next term:

64 × 1/2 = 32

32 × 1/2 = 16

16 × 1/2 = 8

8 × 1/2 = 4

Therefore, the term-to-term rule for this sequence is to multiply each term by 1/2 to obtain the next term.
