Answer:

a. Velocidad = 16 m/s

b. Deceleración = 0.64 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Tiempo = 25 segundos

Distancia = 400 metros.

a. Para encontrar la velocidad;

Velocidad = distancia/tiempo

Velocidad = 400/25

Velocidad = 16 m/s

b. Para encontrar la desaceleración;

Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.

Deceleración = (v - u)/t

Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.

Deceleración = (0-16)/25

Deceleración = 16/25

Deceleración = 0.64 m/s²

Answer:  A. c = 3d

I'm gonna go with c = 3d

Step-by-step explanation:  c = 3d

After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

3          9

5         15

6         18

Now to find equation that models the given data we will use two point slope form.

Formula:

Substitute the values in the formula

where y denotes the number of days and x denotes the cost

Let us suppose d denotes the number of days and c denotes the cost

So, equation becomes:  

Hence an equation models the data in the table is  

So, option A is true.

Answer:

The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.

The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.

A translation happens when either a figure or a function are moved horizontally or vertically.

The four translation rules for functions are given as follows:

Left a units: f(x + a).

Right a units: f(x - a).

Up a units: f(x) + a.

Down a units: f(x) - a.

The parent function for this problem is given as follows:

f(x) = x².

For this problem, the parent function was moved:

2 units left, hence g(x) = f(x + 2).

4 units up, hence g(x) = f(x + 2) + 4.

Hence the function g(x) is defined as follows:

g(x) = (x + 2)² + 4.

(111.5, 155.5)

Step-by-step explanation:

Given the data:

132 127 106 140 158 135 129 138

The Outlier formula :

Lower = Q1 - 1.5(IQR)

Higher = Q3 + 1.5(IQR)

Using a calculator :

Q1 = 128

Median, Q2 = 133.5

Q3 = 139

IQR = Q3 - Q1 = 139 - 128 = 11

Lower = Q1 - 1.5(IQR) = 128 - 1.5(11) = 111.5

Higher = Q3 + 1.5(IQR) = 139 + 1.5(11) = 155.5

(111.5, 155.5)

Answer:

4

Step-by-step explanation:

Given that:

X = time taken to complete mathematics homework

Y= time taken to complete language homework

Standard deviation of X ; SD(X) = 3

Standard deviation of Y ; SD(Y) = 4

rho = - 0.375

rho = Cov(X, Y) / SD(X) * SD(Y)

-0.375 = COV(X, Y) / 3 * 4

COV(X, Y) = 12 * - 0.375

COV(X,Y) = - 4.5

Variance(X, Y) = V(X, Y)

V(X, Y) = V(X) + V(Y) + 2COV(X,Y)

V(X) =SD(X)² = 3² = 9

V(Y) = SD(Y)² = 4² = 16

V(X,Y) = 9 + 16 + 2(-4.5)

V(X, Y) = 16

SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4

Hence, standard deviation to complete entire homework, SD(X, Y) = 4

Answer:

At least $15.50

Step-by-step explanation:

Omar is planning to buy some new baseball shoes. He has already saved $22.50

The shoes cost at least 38 dollars.

At least means, greater than or equal to which is represented by the sign

≥

The inequality is given as

22.50 + x ≥ 38

x ≥ 38 - 22.50

x ≥ 15.5

Therefore, he would need to save at least $15.50

Answer:

32 months.

Step-by-step explanation:

Andy wants a car that costs $8,500.

He already saved $1,300.

$8500 - $1300 = $7200

Andy can save an additional $255 each month.

7200 ÷ 255 = 32

So, it would take Andy 32 months to have enough money to buy the car.

Veronika's net income per month is $3,852. Option B

The annual  amount of taxes that Veronika pays:

Annual taxes = 0.18 x $58,200 = $10,476

Annual health insurance = $125/month x 12 months = $1,500

we can calculate Veronika's net annual income by subtracting the taxes and health insurance from her annual salary:

Net annual income = $58,200 - $10,476 - $1,500 = $46,224

We can calculate her net income per month by dividing her net annual income by 12:

Net monthly income = $46,224/12 = $3,852

Answer:

3x+6

Step-by-step explanation:

inverse means the opposite of the sign and the opposite of subtraction is addition so I used addition

The additive inverse of 3x − 6 is -3x + 6

The additive inverse of a number x is a number that when added to x gives a result of 0.

For the expression 3x - 6

The additive inverse is a number that can be added to the expression to get 0. Hence:

The additive inverse of 3x − 6 is -3x + 6

Step-by-step explanation:

What is the value of this expression? 6 + (-9) - (-5)

6 + (-9) - (-5)

= 6 - 9 + 5

Following the rules of BODMAS, addition comes first before subtraction

= 6 - 14

= - 8

6 + (-9) - (-5) = -8

Note:

- * - = +

- * + = -

+ * - = -

Then using BODMAS

B - bracket

O - of

D - division

M - multiplication

A - addition

S - subtraction

Answer:

D. There is no solution because 9 ≠ -3.

Step-by-step explanation:

For finding out the statement let's check it ourselves

x + 9 - 4x = - 3x - 3

-3x + 9 = - 3x - 3

9 ≠ - 3

So there is no solution for the equation.
