Answer:

y + 2 = [tex]\frac{4}{3}[/tex] (x - 9)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{4}{3}[/tex] and (a, b) = (9, - 2) , thus

y - (- 2) = [tex]\frac{4}{3}[/tex] (x - 9) , that is

y + 2 = [tex]\frac{4}{3}[/tex] (x - 9)

Answer:

y+2 =  4/3( x-9)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point on the line

y - -2 = 4/3( x-9)

y+2 =  4/3( x-9)

Step-by-step explanation:

"The cost, c, to have dinner at Jack's Cafe is at most $25."

In other words, the cost can not go above $25.

This means that the cost c will always be less than or equal to $25.

So, our answer is:

[tex]c\leq 25[/tex]

Answer:

5.76 seconds

Step-by-step explanation:

We are given;

Position of rock from ground level; h(t) = 9 m

Height of cliff;h_0 = 45 m

Velocity;v_0 = 22 m/s

To solve for the time, we will use the gravity formula which is;

h(t) = (-1/2)gt² + (v_0)t + h_0

Plugging in the relevant values to get;

9 = (-1/2)(9.81)t² + 22t + 45

Subtract 9 from both sides to get;

-4.905t² + 22t + 45 - 9 = 0

-4.905t² + 22t + 36 = 0

Finding the roots of the equation through quadratic formula gives;

t = 5.76 or -1.27

t cannot be negative, so we will use the positive value to get;

t = 5.76 s

Thus, the rock will be 9m from the ground level after 5.76 seconds

Probability of having broken glass =  0.1933

Probability of not having broken glass = 0.8067

Step-by-step explanation:

The Treatment table in the file attached to the given question is written out and completed below;

                                                  Treatment

Response       Smashed into             Hit                 Control       Total

      Yes             16                               7                        6             29

Total:                  50                            50                     50           150

Using relative frequencies,

the distribution of responses about whether there was broken glass at the accident for the subjects in this study can be computed as follows:

Probability of having broken glass = [tex]\dfrac{29}{150}[/tex]

Probability of having broken glass =  0.1933

Probability of not having broken glass = [tex]\dfrac{121}{150 }[/tex]

Probability of not having broken glass = 0.8067

Answer:

g(-2) = 0

g(3.14) = 21.2796

Step-by-step explanation:

Simply substitute the values for x.

Step 1: Find g(-2)

g(-2) = (-2)² + 3(-2) + 2

g(-2) = 4 - 6 + 2

g(-2) = -2 + 2

g(-2) = 0

Step 2: Find g(3.14)

g(3.14) = (3.14)² + 3(3.14) + 2

g(3.14) = 9.8596 + 9.42 + 2

g(3.14) = 19.2796 + 2

g(3.14) = 21.2796

Answer:

5000

Step-by-step explanation:

Given the following :

Constructed expression used to express size of debt after m, months :

36,700 - (5000 + 500m)

Since it was stated that he his whole signing bonus was dedicated towards paying his debt, then this will be a constant figure or digit.

Then a fixed amount from his monthly pay is also dedicated towards offsetting the loan:

Thus the fixed amount will be the Coefficient of m, where m is the number of months.

Thus total amount paid after m months can be deduced from the expression to be :

(5000 + 500m); where

5000 constant fee is the signing bonus.

Answer:

  1.5, -8, 0, 2f, 2/3

Step-by-step explanation:

j(x) = 2x means the function name is j, and it is a function of the variable x. To evaluate the function, you put the given value everywhere you see x, and do the arithmetic.

  j(0.75) = 2(0.75) = 1.5

  j(-4) = 2(-4) = -8

  j(0) = 2(0) = 0

  j(f) = 2f

  j(1/3) = 2(1/3) = 2/3

Answer:

Lily has a higher ratio than Logan

Step-by-step explanation:

The True statement is Lily has a higher ratio than Logan

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Column 1              Column 2

       3                        9

       4                        12

       5                        15

       6                        18

Second table

Column 1              Column 2

       4                        10

       6                        15

       12                       30

       14                       35

The ratio from the first table is = 3/9 = 1:3 = 5/15

and, the ratio from the second table is = 4/10 = 2:5= 6/15

Hence, Lily has a higher ratio than Logan.

Answer:

The answer is x = 9

Step-by-step explanation:

(1/3)*x+4 = x-2 // - x-2

(1/3)*x-x+2+4 = 0

Answer:

288

Step-by-step explanation:

To simplify use the mnemonic device PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction)

First simply -6 and 13 (since they are in the parenthesis)

-11+5+6(7)^2

Now find out what 7^2 is

-11 + 5 + 6(49)

Next multiply 6 and 49 (294)

Lastly add 5 then subtract 11 from it

299-11

288

Answer:

Hello! :) I hope I am correct!

Step-by-step explanation:

(The answer should be 288)

Below is the steps!!

Steps:

⇒-6+6(-6+13)^2

⇒-6+6(7^2)

⇒-6+(6)(49)

The answer would be 288 if you solve this equation.

The last step:

⇒-6+294

Which equals 288

Therefore your answer would be 288.

Answer:

26%, 26/100

Step-by-step explanation

The total students will your denominator, and the number "out of" the total will be your numerator, so the fraction is 26/100. Next, convert the fraction into a decimal by dividing 26 by 100, making it 0.26. To convert a decimal into a percent, move the decimal two places to the right, ie, 0.26 becomes 26%.

Answer:

74/100 and 74%

Step-by-step explanation:

Step-by-step explanation:

in this problem, we are expected to convert from miles per hour to feet per second

a). What is her speed in miles per hour?

we know that speed= distance/ time

given that

distance= 26.2 mile

time= 5 hours

substitute and solve for speed we have

speed= 26.2/5

speed= 5.24 miles per hour

b) What is her speed in feet per second?

1 mile per hour is 1.46667 feet per second

5.24 miles per hours will give x

cross multiply to solve for x we have

x= 5.24*1.46667

x= 7.68 feet per seconds

Answer:

Alice is 33 years old.

Step-by-step explanation:

Alice is 3 more than twice Emma's age:

E = Emma

A = Alice

A = 3 + 2E

Sum = 48 years

So,

A + E = 48

(3+ 2E) + E = 48

3 + 2E + E = 48

3 + 3E = 48 (-3 both sides)

3E = 45

E = 45/3

E = 15

Emma is 15 years old.

A = 3 + 2E

A = 3 + 2(15)

A = 3 + 30

A = 33

Alice is 33 years old.

Answer:

[tex]\dfrac{1}{14}[/tex].

Step-by-step explanation:

It is given that,

Red marbles = 3

Blue marbles = 7

Orange marbles = 5

Total marbles = 3+7+5 = 15

Probability of getting a red marble is

[tex]P(Red)=\dfrac{\text{Red marbles}}{\text{Total marbles}}[/tex]

[tex]P(Red)=\dfrac{3}{15}[/tex]

[tex]P(Red)=\dfrac{1}{5}[/tex]

If a marble is drawn from the bag and not replaced. So remaining marbles is 15-1=14. Now,

Probability of getting an orange marble is

[tex]P(orange )=\dfrac{\text{Orange  marbles}}{\text{Total remaining marbles}}[/tex]

[tex]P(orange)=\dfrac{5}{14}[/tex]

Now,

[tex]P(\text{red then orange})=P(Red)\times P(orange)[/tex]

[tex]P(\text{red then orange})=\dfrac{1}{5}\times \dfrac{5}{14}[/tex]

[tex]P(\text{red then orange})=\dfrac{1}{14}[/tex]

Therefore, the required probability is  [tex]\dfrac{1}{14}[/tex].

Answer:

x= 0.348 OR X= -1.148

Step-by-step explanation:

Given that:

2x^2+8+3x^2+4x-10

The first step is to rearrange the parameters given, by doing so, we have:

= 2x^2 +3x^2 +4x -10+8

= 5x^2 +4x - 2

The above equation forms the basis of a quadratic equation;

So using quadratic formula

= (-b +/- (√b^2-4ac))/2a

= (-4 +/- (√4^2 -4*5*(-2))/2*5

= -4 +/- (√ 16 - (-40))/10

=( -4 +/- √ 56 ) / 10

=( -4 +√ 56 ) / 10 OR =( -4 - √ 56 ) / 10

= (-4 + 7.48)/10 OR (-4 -7.48)/10

= 3.48/10 OR -11.48/10

= 0.348 OR. -1.148

SO, x= 0.348 OR X= -1.148

Hey there! I'm happy to help!

All of the sides of a square are the same. Therefore, to find the area, you multiply the side by itself. Multiplying a number by itself is conveniently called squaring.

Doing this backwards is called finding the square root. If you have an area of 64, you square root it, showing you that the sides are 8.

Therefore, the side length here is √94.

If we put √94 into the calculator, we see that it is 9.895359715.....

That number never ends and it goes on in no particular order, so it cannot be written as a fraction of two integers and therefore is not a rational number.
