Step-by-step explanation:

X = sin130° + cos130°

= sin50° - cos50°

= sin50° - sin40°.

sin50° is definitely greater than sin40°, therefore X > 0. (3)

Answer:

y = 1/4x + 0 or just y = 1/4x

Step-by-step explanation:

First I need the slope so I look at the dots and see how much boxes it goes up and then to the side. So it’s up 2 to the side 8. The slope would be 2/8 but you can simply it by 2 and you get 1/4. And the y intercept is given its zero.

Answer:

Step-by-step explanation:

In order for us to be able to get our (x,y) value, we need to show our work step-by-step.

Solving for Y:

  -2x + 3y = -9

+ (2x - 5y = 11)

_____________________

             -2y = 2

             -2     -2

In order for us to be able to find our y value, we need to divide -2 both sides.

y = -1

Solving for X:

2x-5(-1) = 11

2x + 5 = 11

    - 5    -5

_____________________

                 2x = 6

                  2      2

In order for us to find our x value, we need to divide 2 both sides.

x = 3

Our equation set or (x,y) value will be equal to:

(3,-1)

Step-by-step explanation:

Answer and Explanation:

Given the function:

ℎ(t)= −16t+5t+250

Where the variable t is measured in seconds. We can plug in t=20 seconds in the function to measure the height in feet of the bungee jumper after 20 seconds.

h(t)= -16×20+5×20+250

h(t)= -320+100+250

h(t)=350-320

h(t)= 30feet

height in feet of the bungee jumper after 20 seconds = 30 feet

Answer:

D. w = l − 40; the width increases as the length decreases

Step-by-step explanation:

The formula for the perimeter of a rectangle =

P = 2l + 2w

Where to find the Width, we make w the subject of the formula.

Hence:

P - 2l = 2w

w = P - 2l/2

From the question, P = 80

Hence,

w = 80 - 2l/2

w = 80/2 - 2l/2

w = 40 - l

The width of a rectangle is always the longer side ,hence:

D. w = l − 40; the width increases as the length decreases

Answer: $30 + $10h > $140.

Step-by-step explanation: Currently Cassie has $30, so that is the fixed amount of money she has. She needs $140 dollars, so this will be on the left side of your inequality with a "greater than symbol". Cassie can earn $10 an hour, use the variable "h" to represent the number of hours she will work. Set your inequality like this:

$30 + $10h > $140.

The reason why we use a "greater than" sign (>) is that the amount of money Cassie earns needs to be greater than the price of the calculator to be able to buy it.

Answer:

[tex]Gallons = 2.305[/tex]

Step-by-step explanation:

Given

Rate = 130.16 miles for 5 gallons

Required

Number of gallons used for a journey of 60 miles

The rate in miles per gallon is calculated as:

[tex]Rate = \frac{Distance}{Gallons}[/tex]

When distance = 130.16 and gallons = 5, we have:

[tex]Rate = \frac{130.16}{5}[/tex]

[tex]Rate = 26.032[/tex]

When distance = 60 miles.

Substitute 60 for distance and 26.032 for rate in [tex]Rate = \frac{Distance}{Gallons}[/tex]

[tex]26.032 = \frac{60}{Gallons}[/tex]

Cross Multiply

[tex]Gallons * 26.032 = 60[/tex]

[tex]Gallons = \frac{60}{26.032}[/tex]

[tex]Gallons = 2.305[/tex] --- approximated

So , we need to find side of square first

Using area of square = Side²

➩ 144 = S²

➩ S = √144

➩ Side = 12 cm

Now ,

➨ Diagonal = √2 ( 12 )

➨ Diagonal of square = 12√2

Answer:

2.98989/1

Step-by-step explanation:

Answer:

n = 28

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc, then

35 + m = 0.5 × 98 = 49 ( subtract 35 from both sides )

m = 14

∠ n is at the centre subtended on the same arc as ∠ m , thus

n = 2m = 2 × 14 = 28

the answer is B

Answer:

[tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Step-by-step explanation:

In this question, we need to simplify [tex]8x-5+2x\dfrac{x}{y}[/tex]

We can convert elements to fractions.

[tex]8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}[/tex]

= [tex]\dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}[/tex]

As the denominators are equal, we can combine the fractions as follows :

=[tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Hence, the simplified form is : [tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

The population is the large group from which the sample is selected or chosen. In the question given the sample is drawn from the adult population of  San Francisco who are aged 40 to  50 to find out whether they can buy

an electric vehicle sometime in the next year.

The population it can be generalized to is adults living in San Francisco, California.

A population is defined as the group of all the individual members or objects having some common interest or characteristics.

The individual members are called the sampling units or simply units.

Answer:

  a) y = -7/640x^2 +7/4x

  b) y = -7/640(x -80)^2 +70

Step-by-step explanation:

a) Given the equation in standard form:

  y = ax^2 +bx +c

we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.

  a·0 +b·0 +c = 0

  a·80^2 +b·80 +c = 70

  a·160^2 +b·160 +c = 0

The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...

  [tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]

A matrix solver finds the solution to be ...

  a = -0.0109375 = 7/640, b = 1.75 = 7/4

The standard-form equation for Money's path is ...

  y = -7/640x^2 +7/4x

__

b) Factoring out -7/64, we have ...

  y = -7/640(x^2 -160x)

adding and subtracting the square of the x-coefficient, we have ...

  y = -7/640(x^2 -160x +6400) +70

  y = -7/640(x -80)^2 +70

Step-by-step explanation:

Answer:

the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

Step-by-step explanation:

The computation of the number of seconds that you and your friend would be have the similar distance from the starting line is shown below:

As we know that

Speed = Distance ÷ Time

SO,

Time = Distance ÷ speed

= 10 meters ÷ difference in speed

= 10 meters ÷ (6 meters per second - 5.5 meters per second)

= 10 meters ÷ 0.5 meters per second

= 20 seconds

hence, the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds
