What is the graph for y = 4x² + 8x - 1​

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The absolute value function makes no change to a non-negative argument. Here, the argument (x+3) will be non-negative when ...

  x + 3 ≥ 0

  x ≥ -3 . . . . . . condition for the first line

__

When the argument is negative, the absolute value function multiplies it by -1. So the function on the second line is ...

  -1(x+3) = -x -3

and the condition on the second line is ...

  (x +3) < 0

  x < -3 . . . . . condition on the second line

hope it helps

x=-1/3y+4/3

Answer: 2:55 PM

Step-by-step explanation:

Given

The length of the movie is 2 hour and 35 minutes

If the movie is finished at 5:30 PM

First, subtract 2 hours from the finishing time i.e.

[tex]=5:30\ \text{PM}-2\ \text{hr}\\=3:30\ \text{PM}[/tex]

Now, subtract 35 minutes into two parts i.e. 30 min and 5 min from 3:30 PM

[tex]=3:30\ \text{PM}-30\ \text{min}\\=3:00\ \text{PM}[/tex]

remaining 5 min

[tex]=3:00\ \text{PM}-05\ \text{min}\\=2:55\ \text{PM}[/tex]

Thus, the starting time is 2:55 PM

Surface Area: Front+Back+Side1+Side2+Top+Bottom=3320[tex]cm^{2}[/tex]

Volume: [tex]l*w*h[/tex] = 30×10×34=10200[tex]cm^{3}[/tex]

7978 years

Step-by-step explanation:

A = A02^(-t/hl)

where hl = half-life.

Dividing both sides by A0 and taking the logarithm, we get

ln(A/A0) = -(t/hl)ln2

or solving for t,

t= -(hl)ln(A/A0)/ln2

note that A/A0 = 0.38

t = -(5715 yrs)[ln(0.38)/ln2]

= 7978 years

Answer:

92.99

Step-by-step explanation:

Mean, μ = 122.6

Standard deviation, σ = 18

Recall :

Z = (x - μ) / σ

x = score

The Zscore for the lower 5% = 0.05

Using, invnorm(0.05) = - 1.645

Put Z = - 1.645

-1.645 = (x - 122.6) / 18

-1.645 * 18 = x - 122.6

-29.61 = x - 122.6

-29.61 + 122.6 = x

x = 92.99

As triangle is right angled, we can possibly use the Pythagoras theroam.

By pythgoras theoram;

= H² = B² + P²

= 10² = x² + x²

= 10² = x⁴

=⁴√ 10² = x

= 10²×¼ = x

= 10½ = x

= √10 = x

= 3.16 = x

So the value of x is 3.16 cm

(Hypotenuse)² = (Base)²+ (Perpendicular)²

Taking, Hypotenuse As H

Base As B

Perpendicular As P

_________________________

H= 10cm

B= x cm

P= x cm

__________

H²= B²+P²

10²= x²+x²

=> 100= 2x²

=> √100= 2x

=> 10=2x

=> x=10/2

=> x= 5

Answer:

7

Step-by-step explanation:

We know that

a^b / a^c = a^ (b-c)

5^11 / 5^? = 5^(11-?) = 5^4

This means 11-? = 4

11-4 = ?

Answer:

O 68, 14, 3

Step-by-step explanation:

Given:

f(x) = 4x² - x

When x = -4

f(x) = 4x² - x

= 4(-4)² - (-4)

= 4(16) + 4

= 64 + 4

f(x) = 68

When x = 1

f(x) = 4x² - x

= 4(1)² - 1

= 4(1) - 1

= 4 - 1

f(x) = 3

When x = 2

f(x) = 4x² - x

= 4(2)² - 2

= 4(4) - 2

= 16 - 2

f(x) = 14

The answer = 68, 3, 14

Answer:

1716

Step-by-step explanation:

here we have to form arrangements of 3 students

taken from 13 students.

• Where order is important because the positions President, Vice President and Treasurer are not the same.

• also ,repetition is not allowed ,because one student can’t occupy two positions at the same time.

Then ,the number of possible ways

is equal to the number of permutations :

= 13P3

= 13×12×11

= 1716

Answer:

480 in²

Step-by-step explanation:

The Pythagorean Theorem is a²+b²=c², where "a" and "b" are side lengths of a right triangle, and c is the hypotenuse of the right triangle. We are given a side length of 30 inches and a hypotenuse of 34 inches, which will be "a" and "c" respectively. Therefore, we can solve for b, the missing side length:

a²+b²=c²

30²+b²=34²

900+b²=1156

b²=256

b=16

Therefore, the missing side length is 16 inches, making the area of the triangle A=bh=(30)(16)=480 in².

The area is 240

x-2 / x+6

Step-by-step explanation:

I did the math

(I am not 100% sure though, so if I am wrong, someone please mention it!)

The function f(x) . g(x) is a composite function, and the value of f(x) . g(x) is (x- 2)/(x + 6)

A composite function is a function formed by combining multiple independent functions

The functions f(x) and g(x) are given as:

[tex]f(x) = \frac{x + 12}{x^2 + 4x- 12}[/tex]

[tex]g(x) = \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]

The composite function f(x) . g(x) is calculated using:

[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]

Expand the functions

[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4(x^2 - 4x+ 4)}{4(x+ 12)}[/tex]

Cancel out the common factors

[tex]f(x) \cdot g(x) =\frac{1}{x^2 + 4x- 12} * \frac{x^2 - 4x+ 4}{1}[/tex]

Further, expand

[tex]f(x) \cdot g(x) =\frac{1}{(x -2)(x + 6)} * \frac{(x - 2)(x - 2)}{1}[/tex]

Cancel the common factors

[tex]f(x) \cdot g(x) =\frac{x- 2}{x + 6}[/tex]

Hence, the value of f(x) . g(x) is (x- 2)/(x + 6)

To Find :

Angle of the arc BD.

Solution :

From the given figure, ∠BOC = 90°.

∠COD = 120°.

Now, we know, a full circle is, 360°.

So, ∠BOC + ∠COD + ∠BOD = 360°

90° + 120° + ∠BOD = 360°

∠BOD = 150°

Hence, this is the required solution.
