A pebble is tossed into the air from the top of a cliff. The height, in feet, of the pebble over time is modeled by the equation
Charra [1.4K]

Answer:

96

Step-by-step explanation:

The maximum height reached by the pebble modeled by the quadratic function,

h(t)=-16t^2+32t+80, can be found by finding the vertex.

Let's first find the t-coordinate of the vertex . The max height will correspond to this value of t which means we have to find the h(t)-coordinate.

When comparing h to at^2+bt+c, we see that:

a=-16

b=32

c=80

We need to evaluate the following to find the t-coordinate of the vertex:

t=\frac{-b}{2a}

t=\frac{-32}{2(-16)}

t=\frac{-32}{-32}

t=1

So now to find the correspond h(t)-coordinate, we will need to replace t in -16t^2+32t+80 with 1:

-16(1)^2+32(1)+80

-16(1)+32+80

-16+32+80

16+80

A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado l

Question:

The question is incomplete. The display technology was not given. Find below the complete question and the answers.

Display from technology:

Hypothesis Test Results

μ : Mean of variable      

H₀ : μ=2.7 miles

HA  : μ >2.7 miles

Variable     Sample Mean      Std. Err.        DF           T-Stat            P-value

Length            3.23601        0.285185      499        2.230166        0.0131

Step-by-step explanation:

From the result obtained, we have;

Null hypothesis:   H₀ : μ=2.7 miles

Alternative hypothesis:   HA  : μ >2.7 miles

Test statistics = 2.230166

P-value =  0.0131

Significant level: α = 0.05

Since the P value is less than the significance level, we can reject the null hypothesis.

There is no sufficient evidence to support the claim that the mean tornado length is greater than 2.7 miles

an artist is arranging tiles in rows to decorate a wall. each new row has 2 fewer tiles than the row below it. if the first row
valentinak56 [21]

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant

This problem is an Arithmetic Sequence

where

the first term is 23

and

the common difference is -2

In general we can write an Arithmetic Sequence as a rule

an=a1+d*(n-1)

where

a1 is the first term

d is the common difference

so

a1=23\\\\  d=-2

<u>Find the term a7</u>

an=a1+d*(n-1)\\ \\  a7=23+(-2)*[7-1]\\ \\\\ a7=23-12\\ \\\\    a7=11

therefore

<u>the answer is</u>

11\ tiles

cuboid of length 24cm and volume 768cm^3 the width and hight are not equal.give a pair of possible values for their length.​
Brilliant_brown [7]

Answer:

Possible values of dimensions are (24,16,2) or (24,8,4)

Step-by-step explanation:

We are given the volume of the Cuboid and length . We are required to find the possible values of width and height from this information.

Let us say that the width is x and height is y

Length = 24

Volume of a cuboid = length * width * height

Volume = 768

768=24*x*y

xy=\frac{768}{24}\\xy=32\\

xy=32

Now the possible factors of 32

32=1*32 ( Which shall not be taken into consideration as length is already given as 24 and width or height can  not be more length)

32=2*16

32=4*8

Hence the possible values width are 8, 16 and that of height 4 and 2

Hence the possible values of dimensions are (24,16,2) or (24,8,4)
