which graph represents the function h(x)=2sin(x+pi/2)-1 ?

Answer:

To get from ax-5a+4x-20 to a(x-5)+2(2x-10). You had to of found a common factor.

Another (better) way to simply this would be finding the greatest common factor.

a(x-5)+4(x-5)

(a+4)(x-5)

Answer:

0.25

Step-by-step explanation:

La parte decimal de un número decimal exacto está compuesta por una cantidad finita de términos.

Ejemplos:

15.125

0.1

3.0000001

Si en sus factores sólo aparecen 2, 5 o ambos, la fracción es decimal exacta.

Answer:

y = -1/8x + 1

Step-by-step explanation:

Line perpendicular to 8 is -1/8

If the line were to start at the origin, then y- intercept would be 0, and it would pass through the point (-8, 1) To pass through point (-8, 2), add 1 to y in the first example.

Step-by-step explanation:

Calculation to find the probability that the doors were left open

First step is to find the probabilities of doors open and robbed

Probability of door open and robbed =

(25/100)*(5/100)

Probability of door open and robbed= 0.25*0.05

Probability of door open and robbed=0.0125

Second step is to find the probabilities of doors closed and robbed

Probability of door closed and robbed=

(75/100)*(1/100)

Note that 3/4 will give us 75%

Probability of door closed and robbed=0.75*0.01

Probability of door closed and robbed=0.0075

Third step is to find the probability of getting robbed

Probability of getting robbed =0.0075+0.0125

Probability of getting robbed=0.02

Last step is to find the probability that the doors were left open

Using this formula

Probability of open doors = P[door open & robbed] / P[robbed]

Let plug in the formula

Probability of open doors= 0.0125/0.02

Probability of open doors=0.625*100

Probability of open doors=62.5 %

Therefore the probability that the doors were left open will be 0.625 or 62.5 %

Answer:

The area is changing at the point of  [tex]\mathbf{61200 m^2/year}[/tex]

Step-by-step explanation:

From the given information:

Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w

where;

L = length and w = width of the rectangle

Suppose the Length L is twice the width w

Then L = 2w --- (1)

From The area of a rectangle

A = L  × w

A = 2w  × w

A = 2w²

Taking the above differentiating with respect to time

[tex]\dfrac{dA}{dt }= 4w \times \dfrac{dw}{dt} --- (2)[/tex]

At the time t

[tex]\dfrac{dw}{dt}= 34 m \ per \ year ; w = 450 \ m[/tex]

Replacing the values back into equation 2, we get:

[tex]\dfrac{dA}{dt }= 4 \times 450 \times 34[/tex]

[tex]\mathbf{\dfrac{dA}{dt }= 61200 m^2/year}[/tex]

Answer:

12 inches

Step-by-step explanation:

We can write this as a proportion:

inches/miles = inches/miles

1/10 = x/120

Solving for x, we get 12 inches.

Answer:

(P - 1.50) / 16

Step-by-step explanation:

Given that:

Intention = 16 pounds of apple at Kyle's orchard should be $1.50 less than 16 pounds of apple t Pam's orchard.

Let cost of 16 pounds apple at Pam's orchard = p

Kyle's charge per pound will be :

Cost of 16 pound apple at Kyle's orchard :

p - $1.50

If 16 pounds of apple cost p - 1.50

1 pound of apple will cost :

(P - 1.50) / 16

Answer:

1/5 - 4

Step-by-step explanation:

First add -15,  8 and 3 to simplify.

And add 2/5 and -1/5

Now you should have 1/5 - 4

Answer:

There is a value of [tex]c[/tex] in (-1, 1), [tex]c = 0.577[/tex].

Step-by-step explanation:

Let [tex]f(x) = x^{3}+2\cdot x[/tex] for [tex]x \in[-1,1][/tex], we need to prove that [tex]f(x)[/tex] is continuous and differentiable to apply the Mean Value Theorem. Given that [tex]f(x)[/tex] is a polynomical function, its domain comprises all real numbers and therefore, function is continuous.

If [tex]f(x)[/tex] is differentiable, then [tex]f'(x)[/tex] exists for all value of [tex]x[/tex]. By definition of derivative, we obtain the following expression:

[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{(x+h)^{3}+2\cdot (x+h)-x^{3}-2\cdot x}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{x^{3}+3\cdot x^{2}\cdot h+3\cdot x\cdot h^{2}+h^{3}+2\cdot x+2\cdot h-x^{3}-2\cdot x}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} \frac{3\cdot x^{2}\cdot h+3\cdot x\cdot h^{2}+h^{3}+2\cdot h}{h}[/tex]

[tex]f'(x) = \lim_{h \to 0} 3\cdot x^{2}+ \lim_{h \to 0} 3\cdot x \cdot h+ \lim_{h \to 0} h^{2}+ \lim_{h \to 0} 2[/tex]

[tex]f'(x) = 3\cdot x^{2}+2[/tex] (Eq. 2)

The derivative of a cubic function is quadratic function, which is also a polynomic function. Hence, the function is differentiable at the given interval.

According to the Mean Value Theorem, the following relationship is fulfilled:

[tex]f'(c) = \frac{f(1)-f(-1)}{1-(-1)}[/tex] (Eq. 3)

If we know that [tex]f(-1) = -3[/tex], [tex]f(1) = 3[/tex] and [tex]f'(c) = 3\cdot c^{2}+2[/tex], then we expand the definition as follows:

[tex]3\cdot c^{2}+2 = 3[/tex]

[tex]3\cdot c^{2} = 1[/tex]

[tex]c = \sqrt{\frac{1}{3} }[/tex]

[tex]c \approx 0.577[/tex]

There is a value of [tex]c[/tex] in the interval (-1, 1), [tex]c = 0.577[/tex].
