Answer:

In the given expression 7m^3 + 6r^2 - 3r - 8

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Step-by-step explanation:

We are given the expression 7m^3 + 6r^2 - 3r - 8

We need to give variable, coefficients and constant.

Variable: The value of variable may change. It can be represented by x, y or any other letter

Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient

Constant: It is fixed value. It cannot be changed.

So, in the given expression 7m^3 + 6r^2 - 3r - 8

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

A ball is thrown upward from a height of 15 ft with an initial velocity of 5 ft/s. Use the equation h=-16t^2+5t+15 to answer the
Fiesta28 [93]

Answer:

1) 1.1 seconds

2) 13.5 feet

<h3>Part A</h3>

\rightarrow \sf  -16t^2 + 5t + 15 = 0

<u>Apply quadratic formula</u>:

\rightarrow \sf t=   \dfrac{-5\pm \sqrt{5^2-4\left(-16\right)\cdot \:15}}{2\left(-16\right)}

<u>Simplify following</u>

\rightarrow \sf t=-\dfrac{-5+\sqrt{985}}{32},\:t=\dfrac{5+\sqrt{985}}{32}

In decimal form:

\rightarrow \sf t=-0.825 ,\:t=1.137

Conclusion:

As time is be only positive: t = 1.1 seconds

<h3>Part B</h3>

\rightarrow \sf  h=-16t^2 + 5t + 15

<u>insert t = 0.5</u>

\rightarrow \sf  h=-16(0.5)^2 + 5(0.5) + 15

<u>simplify</u>

\rightarrow \sf  h=13.5

A pair of dice is rolled, and the sum of the numbers is either 7 or 11. What is the probability of this event?
AfilCa [17]

Answer:   \dfrac{2}{9}

Step-by-step explanation:

Let A be the event that the sum is 7 and and B be the event that the sum is 11 .

When two pair of dices rolled the total number of outcomes = n(S)=6\times6=36

The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}

Thus n(A)= 6

The sample space of event B = {(5,6), (6,5)}

n(B)=2

Since , both the events are independent , then the required probability is given by :-

P(A\cup B)=P(A)+P(B)\\\\=\dfrac{n(A)}{n(S)}+\dfrac{n(B)}{n(S)}=\dfrac{6}{36}+\dfrac{2}{36}=\dfrac{8}{36}=\dfrac{2}{9}

Hence, the required probability = \dfrac{2}{9}

5 12 14 will form a acute?<br> True or false
monitta

No it won't. it's false

cuz proofs here.

(5²)+(12²)= (169)

√(169) = 13

.. so if 13 was the number at 14

it would have been true.

currently the answer is false
