Answer:

OPTION 2

Step-by-step explanation:

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular  x   value. The   y   value of a point where a vertical line intersects a graph represents an output for that input  x   value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that   x   value has more than one output. A function has only one output value for each input value.

--------------------------------------------------------------------------

HOW TO: GIVEN A GRAPH, USE THE VERTICAL LINE TEST TO DETERMINE IF THE GRAPH REPRESENTS A FUNCTION.

1.Inspect the graph to see if any vertical line drawn would intersect the curve more than once.

2.If there is any such line, the graph does not represent a function.

3.If no vertical line can intersect the curve more than once, the graph does represent a function.

(The 2nd pic represents a graph that has a function)

Building to the left is taller.

Step-by-step explanation:

Kindly refer to the attached diagram for the given dimensions.

[tex]\triangle ABR, \triangle PQR[/tex]

AB and PQ be the two buildings.

The car be parked at point R.

[tex]\angle ARB = 50^\circ\ and \\\angle PRQ = 40^\circ[/tex]

Distance of R from building bases:

BR = 49 m

QR = 56 m

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan40 = \dfrac{h_1}{56}\\\Rightarrow h_1 = 56 \times 0.839 \\\Rightarrow h_1 \approx 47\ m[/tex]

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan50 = \dfrac{h_2}{49}\\\Rightarrow h_2 = 49 \times 1.19 \\\Rightarrow h_2 \approx 58.4\ m[/tex]

So, building to the left is taller.

Answer:

y=x-6

Step-by-step explanation:

Y=x+3 according to this equation, the gradient is 1 comparing to y=mx+c. so m is the gradient. so from the equation, the coefficient of x is 1. since the line is parallel so it means the new equation has the same gradient m.

y=x+c but it passes through 1,-5...when x= 1, y=-5 from here , we Can find the new intercept c. -5=1+c. so c=-5-1=-6

the new equation y=x-6

Step-by-step explanation:

Answer:

x = -16

Step-by-step explanation:

3x+11 = 2x - 5

x +11 = -5 (Get x's on one side by substracting 2x from both sides)

x= -16 ( substract 11 from both sides to get the answer

Answer:

[tex]x=-16[/tex]

Step-by-step explanation:

[tex]3x+11=2x-5[/tex]

Subtract 11 from both sides:

[tex]\hookrightarrow[/tex] [tex]3x+11-11=2x-5-11[/tex]

[tex]\hookrightarrow 3x=2x-16[/tex]

Subtract 2x from both sides:

[tex]\hookrightarrow 3x-2x=2x-16-2x[/tex]

[tex]\hookrightarrow x=-16[/tex]

Answer:

  4,691,902

Step-by-step explanation:

There are 5280 ft per mile, and 12 inches per foot. There are 178.7 inches per Prius. The number needed is ...

  (13233 mi)(5280 ft/mi)(12 in/ft)/(178.7 in/Prius)

  = (13233×5280×12/178.7) Prius

  = 4,691,901.95 Prius

With a little squeezing, you could gain the extra 7.4 inches necessary to round this number to the next higher integer value:

[tex]7.25 \leqslant x[/tex]

Step-by-step explanation:

you do 1.5×8 to see how much shipping cost

you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25

so he needs to spend $7.25 or more on each friend. (im pretty sure)

The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.

Let the cost of each gift = c

urgio is buying gifts for 8 friends = 8 gifts

Hence, the Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

Answer:  195 inches.

Step-by-step explanation:

Given: Sam is building a model of an antique car.

The scale of his model to the actual car is 1:10.

⇒Scale factor = [tex]\dfrac1{10}[/tex]

Since,  Length of actual figure = (Length of model ) ÷ Scale factor.

If length of model of car = 19.5 inches.

Then, the length of the actual car = [tex]19.5\div\dfrac{1}{10}=19.5\times10=195\text{ inches}[/tex]

Hence, the length of the actual car  = 195 inches.

Answer: 8

Step-by-step explanation:

Let mammals be represented by y

There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3

There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7

y + y + 3 + y - 7 = 41

3y - 4 = 41

3y = 41 + 4

3y = 45

y = 45/3

y = 15

Since amphibian = y - 7

= 15 - 7

= 8

There are 8 amphibians

Answer:

490 female students

Step-by-step explanation:

If 70% of students are female, 30% are male.

If 30% of students = 210 students, we can divide both sides of the equation by 3.

30/3 = 10

210/3 = 70

10% of students = 70 students

To get 70% of students, multiply both sides by 7.

10*7 = 70

70 * 7 = 490

70% of students = 490 students

Answer:

13½ kilometers

Step-by-step explanation:

If Nina runs 4½ km in ⅓ of an hour, at this pace, the number of km she'd run in an hour can be calculated as follows.

Let x be the number of km to run in an hour.

4½km => ⅓ hr

x km => 1 hr

Cross multiply

[tex] 1*4\frac{1}{2} = \frac{1}{3}*x [/tex]

[tex] 4\frac{1}{2} = \frac{x}{3} [/tex]

Multiply both sides by 3

[tex] 4\frac{1}{2}*3 = \frac{x}{3}*3  [/tex]

[tex] \frac{9}{2}*3 = x  [/tex]

[tex] \frac{27}{2} = x [/tex]

[tex] 13\frac{1}{2} = x [/tex]

x = number of km Nina runs in 1 hour = 13½ kilometers

square number of 1467=2,152,089

The solution is 1764

The number on rearranging is given by the equation A = 1764 , where the square root of the number is B = 42

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the set of numbers is = { 1 , 4 , 6 , 7 }

The square root of the number be B

The value of B = 42

So , the square of the number B² = 42 x 42

Square of the number B² = 1764

Therefore , the value of A = 1764

Hence , the number is 1764

Answer:

volume of toy = volume of water after placing toy in it - volume of water before placing toy in it

The increase in the volume of water when the toy is submerged in it is equal to the volume of the toy.

SO VOLUME OF WATER IS 13mL

Answer:

The piece-wise function is;

[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]

Step-by-step explanation:

The flat rate for renting the car = $35 per day

The amount charged as insurance fee per day for renting the car for 3 days or less = $10

The insurance fee charged per day when the car is rented for more than 3 days = $5

Let the number of days = x

Therefore, we have;

For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x

For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x

Therefore;

The charge rate for renting the car for less than or equal to 3 days = 45·x

The charge rate for renting the car for more than 3 days = 40·x

The piece-wise function can be presented as follows;

[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]

Step-by-step explanation:

A function shows the relationship between two variables (an independent and dependent variable). The independent variable is not dependent on other variables, it is considered as the input while the dependent variable is dependent on other variables and considered as output.

The speed of Marcus must not be faster than 65 mph, hence speed ≤ 65 mph. This means that Marcus can drive with speed ranging from 0 mph to 65 mph, hence 0 ≤ speed ≤ 65 mph. This is represented using the interval notation:
