Answer:

6 seconds after it is launched

Step-by-step explanation:

h(t) = -4t² + 16t + 48

The balloon is at ground level when it lands.

When it is launched, t = 0, and h(0) = 48

When it lands, at time t, h(t) = 0.

-4t² + 16t + 48 = 0

t² - 4t - 12 = 0

(t - 6)(t + 2) = 0

t = 6 or t = -2

The balloon will hit the ground 6 seconds after it is launched.

Find the probability if two dice are rolled. (Enter the value of probability in decimals. Round the answer to three decimal plac
enyata [817]

The probability of getting a total of 8 when two dice are rolled is 0.139 when the answer is rounded to three decimal places.

<h3>What is meant by Probability?</h3>

Numerous uses of mathematics' probability formula may be found. Probability can be used, for instance, to determine the likelihood that a certain marketing would really be successful in generating fresh customers. Calculating the likelihood of something happening is another use of probability.

Let's examine what probability is, how to compute the probabilities of single and many random occurrences, and how the terms probability and odds vary from one another.

The likelihood that an event like rolling two dice will occur is determined by probability:

P(A) = f / N

Odds and probability are connected, but the probability determines the odds. Probability is required before calculating the likelihood of an occurrence.

The probability is P(getting a total of 8 from both dices)=5/36= 0.139.

The triangles shown above are similar. State the pairs of corresponding angles the images are not drawn to scale
melamori03 [73]
We know that
∠X≈∠B
∠Y≈∠C
∠Z≈∠A

XZ≈BA
XZ=12
BA=9

XY≈BC
XY=14
BC=10.5

ZY≈AC
ZY=16
AC=12

the scale factor=12/16-----> 0.75

therefore

the answer is the option D

Which is the graph of f(x) = 5(2)x?
gayaneshka [121]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=5(2)^{x}  

This is a exponential function of the form

f(x)=a(b)^{x}  

where

a is the initial value

b is the base

In this problem

a=5

b=2

using a graphing tool

see the attached figure
