What is the value of f(x) when x = -1
f(x) = 2* + 5

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can use this formula to find the equation of the line

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y - 11)/(23-11) = (x-1)/(3-1)

(y-11)/12 = (x-1)/2

y-11 = 6x-6

y = 6x + 5

the rate of change is the slope of the line, while the constant (5) is the y intercept

Answer:

The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn.

Answer: the correct answer is A. 35, 55

Step-by-step explanation: got it right on my exam today

35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Congruent angles are the angles that have equal measures.

According to the given  question

We have different angles for [tex]sinx[/tex] and  [tex]cosy[/tex].

And we have to find "the pairs of angles which has congruent values for sinx and cosy.

Therefore,

35 degree and 55 degree

sin(35) = [tex]sin(\frac{7\pi }{36})[/tex] =0.57

cos(35) = [tex]cos(\frac{11\pi }{36})[/tex] = 0.57

⇒ 35 degrees and 55 degrees are the pair of angles has congruent values for sinx and cosy.

35 degrees and 70 degrees

sin(35) =[tex]sin(\frac{7\pi }{36} ) =0.57[/tex]

cos(70) =[tex]cos(\frac{7\pi }{18} )[/tex] = 0.34

⇒35 degrees and 70 degrees are the pair of angles have not congruent values for sinx and cosy.

35 degrees and 145 degrees.

sin(35)=[tex]sin(\frac{7\pi }{36} )= 0.57[/tex]

cos(145) = [tex]cos(\frac{29\pi }{36} )= -0.8[/tex]

⇒ 35 degrees and 145 degrees are the pair of angles have not congruent values for the sinx and cox.

35 degrees and 55 degrees

sin(35) =[tex]sin(\frac{7\pi }{36} )[/tex]= 0.57

cos(35) = [tex]\frac{x}{y} =\frac{7\pi }{36} = 0.8[/tex]

⇒ 35 degrees and 55 degrees are the pairs of angles have not congruent values for sinx and cosx.

Hence, 35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Answer:

30

Step-by-step explanation:

Given that,

No. of pairs of pants = 3

No. of shirts = 5

No. of pairs of shoes = 2

No. of different outfits that Jane can choose from = 3 * 5 * 2

= 30

∵ The maximum number of different outfits would be 30.

Basically, an outlier is a point on a graph that doesn't really fit the pattern.

An outlier can throw off a mean, if the outlier is larger than the other points, it can make the mean much higher than it should be. Vice versa, if it is smaller, the mean is much lower.

Answer:

4 1/11 hours

Step-by-step explanation:

Tom can paint 1/6 of the fence in an hour

Huck can paint 1/5 of the fence in an hour

Tom takes a half-hour break; we can create this equation:

1/6x - 1/2 + 1/5x = 1

use a denominator of 30:

5x/30 - 15/30 + 6x/30 = 30/30

11x/30 = 45/30

multiply each side by 30/11 to get:

x = 45/11 or 4 1/11

Answer:

x = {2, 8}

Step-by-step explanation:

(x - 3)^2 = 25

Take the square root of both sides

x - 3 = ±5

Add 3 to both sides

x = ±5 + 3

x = 5 +3 = 8

x = -5 + 3 = 2

x = {2, 8}

Answer:

x = 8, -2

Step-by-step explanation:

[tex](x-3)^2=25[/tex]

[tex](8-3)^2=25[/tex]          Substitute x for 8 the subtract 8 - 3

[tex](5)^2=25[/tex]                Multiply 5 by 5

[tex]25=25[/tex]

[tex](x-3)^2=25[/tex]

[tex](-2-3)^2=25[/tex]       Substitute x for -2 then subtract -2 - 3

[tex](-5)^2=25[/tex]             Multiply -5 by -5

[tex]25 = 25[/tex]

Answer:

The mean is 6.

Step-by-step explanation:

To find the mean you need to do the following.

first, add up all the data to get a total.

next, count the amount of data you have.

lastly, divide the total by the count.

Answer:

6

Step-by-step explanation:

our given database is

2,3,6,6,7,8,8,8

add up all data:

[tex] \displaystyle \rm2 + 3 + 6 + 6+ 7 + 8 + 8 + 8[/tex]

[tex] \displaystyle = 48[/tex]

count the amount of data:

[tex] \displaystyle \boxed{ \begin{array} {ccc} \text{we have two 1 time} \\\text{we have three 1 time} \\ \text{we have six 2 times} \\ \text{we have seven 1 time} \\ \text{we have eight 3 time} \\ \hline \text{total} \quad \quad8\end{array}}[/tex]

divide the total by the count:

[tex] \displaystyle \frac{48}{8} [/tex]

[tex] \displaystyle = 6[/tex]

hence,

the mean of the database is 6

Answer:

The value of the mutual force between them is 3.6 x 10⁶ N

Step-by-step explanation:

Given;

distance between the two-point charges, r = 2000 m

the value of the two-point charges, q₁ and q₂ = 40 C and -40 C

Coulomb's constant, k = 9 x 10⁹ Nm²/C²

The value of the mutual force between them is calculated by applying Coulomb's law;

[tex]F = \frac{K|q_1|q_2|}{r^2} \\\\F = \frac{(9 \times 10^9)(40\times 40)}{(2000)^2} \\\\F = 3.6 \times 10^6 \ N[/tex]

Therefore, the value of the mutual force between them is 3.6 x 10⁶ N.

Answer:

x = 6

m∡ABC = 135°

Step-by-step explanation:

∡ABE ≅ ∡CBD therefore we can create the following equation:

3x + 27 = 45

3x = 18

x = 6

∡CBD and ∡ABC are supplementary so 180 - ∡CBD = m∡ABC

180 - 45 = m∡ABC

m∡ABC = 135°
