18 seconds

Step-by-step explanation:

The object will reach the ground when its height h(t) = 0. Therefore, we can write

[tex]h(t) = 288t - 16t^2 = 0 \Rightarrow 16t^2 = 288t[/tex]

Solving for t, we get

[tex]16t = 288 \Rightarrow t = 18\:\text{s}[/tex]

To Find :-

Solution :-

Here since the slope of the line is 7 and y intercept is -7 , we can use the slope intercept form of the line to find the equation of the line . The slope intercept form of the line is ,

[tex]\longrightarrow[/tex] y = mx + c

On putting the respective values ,

[tex]\longrightarrow[/tex] y = 7(x) + (-7)

[tex]\longrightarrow[/tex] y = 7x - 7

im sorry if its not cleear to explain

Using the logarithmic function, it is found that:

a) The initial score is of 92.

b) After 6 months, the score is of 88.6.

c) After 18 months, the score is of 86.9.

The average score after t months is modeled by:

[tex]f(t) = 92 - 4\log{(t + 1)}[/tex]

Item a:

The initial score is of f(0), hence:

[tex]f(0) = 92 - 4\log{1} = 92 - 0 = 92[/tex]

The initial score is of 92.

Item b:

After 6 months, the score is of f(6), hence:

[tex]f(6) = 92 - 4\log{7} = 88.6[/tex]

After 6 months, the score is of 88.6.

Item c:

After 18 months, the score is of f(18), hence:

[tex]f(6) = 92 - 4\log{19} = 86.9[/tex]

After 18 months, the score is of 86.9.

Step-by-step explanation:

The probability that both are red marbles = [tex]\bold{\frac{17}{147} }[/tex]

"It is finding out the possibilities of the occurrence of an event."

"P(A) = n(A) / n(S)

where, n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment"

For given example,

A jar contains 17 red marbles and 32 blue marbles.

If we pull out 2 marbles at random, we need to find the probability that both are red.

The number of possible outcomes,

[tex]\Rightarrow n(S)=^{49}C_2\\\\ \Rightarrow n(S)=\frac{49!}{2!(49-2)!}\\\\ \Rightarrow n(S)=1176[/tex]

The number of possible outcomes of selecting both the red marbles.

[tex]\Rightarrow n(A)=^{17}C_2\\\\ \Rightarrow n(A)=\frac{17!}{2!(17-2)!}\\\\ \Rightarrow n(A)=136[/tex]

The probability that both the marbles are red,

[tex]\Rightarrow P(A)=\frac{n(A)}{n(S)}\\\\ \Rightarrow P(A)=\frac{136}{1176}\\\\ \Rightarrow P(A)=\frac{17}{147}[/tex]

Therefore, the probability that both are red marbles = [tex]\bold{\frac{17}{147} }[/tex]

Answer:

68

Step-by-step explanation:

8 boxes. 10 per one box. 8×10=80

80-12= 68

Answer:

we need to find out if the following get x = 2 as a final product

-2(x-4) = 4

-2x + 8 = 4

-2x = -4

x = 2

so it is a solution

26/x = 13

26 = 13x

x = 26/13

x = 2

so it’s a solution

-3.8x = -7.4

x = 7.4/3.8 ≠ 2

you get ≈ 1.95

so it’s not a solution

4(x-1) - 3(x-2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -10

so it’s not a solution

Answer:

x= 2 is the solution of first two equations.

Step-by-step explanation:

4, 5, 6, 7 & 8 are exterior angles.

Answer:

See answers below.

Step-by-step explanation:

Exterior angles are angles that form a linear pair with an angle of a triangle.

Remote interiors in a triangle are the angles that are not adjacent to an exterior angle of the triangle (meaning are not connected to the exterior angle)

A. Exterior angles are ∠8, ∠7, ∠5,  ∠4, and ∠6

B.   Remote interiors angles are :

      Looking at ∠6, the remote interior angles are ∠1 and ∠2

      Looking at ∠8, the remote interior angles are  ∠1 and ∠2

      Looking at  ∠5, the remote interion angles are ∠1 and ∠3

C.   ∠6 and ∠8 are vertical angles which are ≅ and equal.
