If you meant 45 minutes, no.
45 x 60 is 2700
2700=/=750

You are moving the robot to your classroom, which measures 30 feet by 40 feet.

AlladinOne [14]

Answer:

1) See figure attached

a) $d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}$

And if we replace we got:

$d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211$

b) $V = \frac{d}{t}$

And if we replace we got:

$V = \frac{7.211 ft}{2 sec}=3.606 s$

Step-by-step explanation:

Part 1

We can see the plot in the figure attached.

Part 2

For this case we have two points $(x_1 , y_1) = (6,9) , (x_2 , y_2) = (10,15)$

And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:

$d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}$

And if we replace we got:

$d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211$

Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:

$V = \frac{d}{t}$

And if we replace we got:

$V = \frac{7.211 ft}{2 sec}=3.606 s$

Condense the following logs into a single log:

mamaluj [8]

QUESTION 1

The given logarithm is

$8\log_g(x)+5\log_g(y)$

We apply the power rule of logarithms; $n\log_a(m)=\log_(m^n)$

$=\log_g(x^8)+\log_g(y^5)$

We now apply the product rule of logarithm;

$\log_a(m)+\log_a(n)=\log_a(mn)$

$=\log_g(x^8y^5)$

QUESTION 2

The given logarithm is

$8\log_5(x)+\frac{3}{4}\log_5(y)-5\log_5(z)$

We apply the power rule of logarithm to get;

$=\log_5(x^8)+\log_5(y^{\frac{3}{4}})-\log_5(z^5)$

We apply the product to obtain;

$=\log_5(x^8\times y^{\frac{3}{4}})-\log_5(z^5)$

We apply the quotient rule; $\log_a(m)-\log_a(n)=\log_a(\frac{m}{n} )$

$=\log_5(\frac{x^8\times y^{\frac{3}{4}}}{z^5})$

$=\log_5(\frac{x^8 \sqrt[4]{y^3} }{z^5})$

Jayla ate 75% of the jelly beans in the bag. If she ate 24 jelly beans how many were in the bag?

maksim [4K]

Answer:

32 jelly beans were in the bag

Step-by-step explanation:

We know 75% is 3/4 and that she ate 24, so divide 24 by 3 then multiply it by 4:

24/3= 8

8 x 4 = 32

Area = 9.3 cm squared

Step-by-step explanation:

Perimeter: Add sides: 3.1 + 9.3 + 7.2 = 19.6

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H

Yuliya22 [10]

From the problem we know that Hanna saves one-half of her paycheck each week, so she saves $( \frac{1}{2})(160)= \frac{160}{2} =80$ . Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is $80+50=130$ .
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span> $n$ representing the number of weeks, we can model the situation as follows:
$f(n)=1280+130n$
