The zeros of the quadratic x^2+4x=-2x+16 are x=-8 and x=2. What does this tell you about the graph of this quadratic function?

a. The parabola crosses the x-axis at x=-8 and x=2.
b. The parabola touches the x-axis only at and x=2.
c. The parabola does not touch or cross the x-axis.
d. The parabola crosses the x-axis at x=-8 and x=2 but you can ignore the zero x=-8 because it is negative.

Answers

The graph of the quadratic function x²+4x=-2x+16 is a parabola that crosses the x-axis at x=-8 and x=2. Correct option is (a).

What are zeros and graph of an quadratic equation?

Let ax² +bx +c = 0 is an quadratic equation its zeroes are the values of x for which the Left hand side becomes zero.

To find zeroes we can use quadratic formula that is

x = (-b ±√(b²-4ac))/2

Graph of the quadratic equation are points ( x , y(x) )

where y(x) =  ax² +bx +c

when x= t is zero of quadratic equation ax² +bx +c = 0

then y(t) = 0

(t, 0) points are points on the x-axis.

Given an quadratic equation

x²+4x=-2x+16 has roots x =-8 and x =2

This can we written as  x² +6x -16 =0

The graph of  this quadratic equation is given by (x, y(x))

where y = x² +6x -16 which is a parabola

for x= -8 and x= 2 , y(-8) =y(2) = 0

Then (-8,0)  and (2,0) are points on this parabola which are at x-axis

Therefore, the parabola y = x² +6x -16  crosses the x-axis at x=-8 and x=2.Thus (a) is the correct option.

Step-by-step explanation:

You just multiply the $100 by the change rate to get the new currency

Answer:

Step-by-step explanation:

You are traveling to Japan and need Japanese Yen (JPY)

We need to convert $100 USD to JPY

If conversion rate is $1USD = 0.9333JPY

The value of $1 USD is 0.9333 JPY

Let in $100 USD get x JPY

 100/.9333

A flat screen tv at Best Buy costs $699 . The sales tax in Virginia is 5.3%. How much tax will you pay on the TV?

Answers

Answer:

736.05

Step-by-step explanation:699.00 x 5.3%=37.047

699.00 + 37.05 = 736.05

Answer:

$37.05

Step-by-step explanation:

$699 × 5.3%

We must convert 5.3% into just a decimal (not a percentage)

To do so, move the decimal to the left two places.

This would be 0.053

699 × 0.053 = 37.047

Although the exact number is 37.047, money is only paid within two decimals places, so let's round up to the nearest hundredth place

37.047 rounds up to 37.05

$37.05 is how much tax will be paid on the TV

Question:

Which interest rate is missing from Renee’s table?

Answer:

Principal- $750

Interest Rate- $00.5

Time- 11 yrs. (Years)

Interest- $412.50

Explanation:

To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. ...

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved.

r = Interest rate in decimal.

Therefore we get an answer of $00.5

Because M is a midpoint, for both questions, the equations on M's either sides are equal.

9) 5x+9=24

Subtract 9 from both sides

5x=15

Divide by 5 on both sides

x=3

10) 3x-7=x+10

Add 7 to both sides and subtract x from both sides

2x=17

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the same speed?

Answers

Answer:

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

They did not run at same speed

Step-by-step explanation:

formula of speed = distance covered/ time taken

For Andre

Distance = 2 KM

time = 15 mins

60 mins = 1 hour

15 mins = 1/60 * 15 hour = 0.25 hours

thus,

speed = 2km/0.25 hour = 8 km per hour

Similarly for Jada

Distance = 3 KM

time = 20 mins

60 mins = 1 hour

20 mins = 1/60 * 20 hour = 1/3 hours

thus,

speed = 2km/(1/3)hour = 6  km per hour

Now we have

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

Review the incomplete derivation of the cosine sum identity.

A 2-column table with 5 rows. Column 1 has entries step 1, step 2, step 3, step 4, step 5.

Which expressions for Step 3 and Step 5 complete the derivation?

Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) – sin(x)sin(y)

Answer:

Step-by-step explanation:

STEP - 1

cos(x + y)

STEP - 2

[tex]\text{sin}[\frac{\pi}{2}-(x+y)][/tex]

STEP - 3

[tex]\text{sin}[(\frac{\pi}{2}-x)-y][/tex]

STEP - 4

[tex]\text{sin}(\frac{\pi}{2}-x)\text{cos}(-y)+\text{cos}(\frac{\pi}{2}-x)\text{sin}(-y)[/tex]

STEP - 5

cos(x)cos(y) - sin(x)sin(y)

[Since, [tex]\text{sin}(\frac{\pi}{2}-x)=cos(x)[/tex] and [tex]\text{cos}(\frac{\pi}{2}-x)=\text{sin}(x)[/tex]]

[Since, cos(-x) = cos(x) and sin(-x) = -sin(x)]

Therefore, Option (4) will be the correct option.
