The graph of the equation h=-at^2+bt+c, which describes how the height, h, of a hit baseball changes over time, t, is shown below.

Answer:

C.) 1

Step-by-step explanation:

EDG 2020

The value of f(g(0)) is 1.

Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).

h(x) is called the composite function.

Given a table which shows values for the two functions f and g for different values of x.

We have to find the value of f(g(0)).

f(g(0)) = f[ g(0)]

From the table, g(0) = -1.

f(g(0)) = f(-1) = 1

Hence the value of f(g(0)) is 1.

answer:

the opposite of 6 is -6 and the absolute value of 6 is 6

explanation:

cause its 6 <3

The opposite of the number is -6 and its absolute value is 6.

We have a number -  6.

We have to find out the opposite and the absolute value of the number.

For a number - 'n', its opposite is '- n' and the absolute value of a number - 'n' is -

[tex]$n=\left \{ {{n} \;\;\;for \;n > 0\atop {-n}\;\;\;for\;n < 0} \right.[/tex]

We have a number = 6.

The opposite of the number = - 6.

The absolute value of a number = 6.

Hence, the opposite of the number is -6 and its absolute value is 6.

Answer:

A =72 in^2

When dilated

    =1152 in ^2

Step-by-step explanation:

The area of the triangle is

A = 1/2 bh

We need to convert the units to match

2 ft= 24 inches

A = 1/2 ( 24*6)

A = 1/2 (144)

A =72 in^2

When dilated 6 inches *4 = 24 inches

                      24 inches *4 = 96 inches

A = 1/2 ( 96*24)

   = 1/2(2304)

    =1152 in ^2

Answer:

D

Step-by-step explanation:

the answer you chose is correct because if you isolate x (shown below), you end up with -5. there is also no equal sign under the less than symbol, so that means it is an open circle, which it is. however, you must flip the sign when multiplying or dividing by a negative number in inequalities, so this becomes a greater than symbol, showing that x is greater than -5. this accurately portrays the given inequality on the number line.

Step: Solvey=7x+12for y:

y=7x+12

Step: Substitute7x+12foryiny=7x+2:

y=7x+2

7x+12=7x+2

7x+12+−7x=7x+2+−7x(Add -7x to both sides)

The value of x so that lines c and d are parallel lines cut by transversal p is 12

From the given figure, the sum of the given angles is supplementary, that is:

3x + 45 =  81

Subtract 45 from both sides

3x + 45 -45 = 81  - 45

3x = 36

x = 12

Hence  the value of x so that lines c and d are parallel lines cut by transversal p is 12

The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Given that, a triangle PQR with side lengths 6 cm, 7 cm, and 11 cm.

Considering option 1) 24 cm, 28 cm, 44 cm

To see the similarity, we will check if the ratio of the corresponding sides are equal or not,

6/24 = 1/4

7/28 = 1/4

11/44 = 1/4

That means, 6/24 = 7/28 = 11/44 = 1/4

Since, the corresponding sides of these triangles are in equal ratios,

Hence, The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm
