Answer:

55 mph

Step-by-step explanation:

First hour: 40 mph

Second, Third, Fourth hours:

180 miles / 3 hours = 60 mph

Average: 40 (hour 1) + 60 (hour 2) + 60 (hour 3) + 60 (hour 4) = 220 / 4 hours = 55 mph average

I hope this helps!

Which function has a range of y&lt;3?<br> y=3(2)<br> y=2(3)*<br> y=-(2)* + 3<br> y= (2)X-3
Bingel [31]

The function that has a range of y<3 is y=-(2)* + 3

Answer: Option(c)

<u>Step-by-step explanation:</u>

Solution:

Lets shall evaluate the options given in the question

In Option 1; y=3(2) that is

y=3 \times 2=6

So the value of y>3 and thus option 1 fails

In option 2; y=2(3)*

This expression indicates that the power of 3 all result in positive values and sometimes zero such that for 2 \times 3^{0}=0 and for values other than one y will be greater than 3. so option 2 fails.

In option 4; y=2x(-3)

On solving we get y=2 \times(-3)=-6

Though it is less than 3 but it has an negative value. So option 4 fails.

In option 3; y=-(2)* + 3

This option indicates for all power values of -2 the y value will be less than 3 such that

For power value 0 we get

y=-2^{0}+3

y=0+3=3

And for the power value 1 we get

y=-2^{1}+3

y=-2+3=1

So in the both the occasion the value of y<3 than and it is not an negative value and thus option 3 satisfy the functional range y<3.

Result:

Thus the function that has a range of y<3 is y=-(2)* + 3

1.<br> Find m2ABC.<br> А<br> (6x - 7)º<br> B<br> (4x + 23)
Nikolay [14]

Answer:

6x-7=4x+23

6x-4x=23+7

2x=30

2x/2 = 30/2

X=15

hence, 4(15)+23

60+23=83

B+83=180

B=180-83

B=97

(8z^8/4z^4)^-4 please help me to solve this
Anni [7]
8 / 4 = 2 ;
z^8 / z^4 = z^4 ;
then, 8z^4 / 4z^4 = 2z^4 ;
finally, ( 8z^4 / 4z^4 )^ -4 = ( 2z^4 )^ - 4 = 1 / ( 2z^4 )^4 = 1 / [ 2^4 * ( z^4 )^ 4 ] = 1 / ( 16 * z^16 )

There are many cylinders for which the height and radius are the same value. Let
VashaNatasha [74]

Answer:

Relation between V and c is represented as:

V = \pi c^{3}

When c is halved, V becomes \frac{1}{8} of its initial value.

Step-by-step explanation:

Height of cylinder = Radius of cylinder = c

Volume of cylinder = V

As per formula:

V = \pi r^{2} h

Where r is the radius of cylinder and

h is the height of cylinder

Putting r = h =c

V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)

The values of c is halved:

Using equation (1), New volume:

V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}

By equation (1), putting \pi \times c^{3}  = V

V' = \dfrac{1}{8} \times V

So, when c is halved, V becomes \frac{1}{8} of its initial value.
