Answer 1

Answer: 1) √3 √7 = √21
2) √5 √245 = √5 √5 * 49 = √5 * 7√5 = 7 √5 * 5 = 7 √25 = 7 * 5 = 35
3) √77 ÷ √11 = as is. can't be simplified.
4) (√59)² = 59 ; the square root was cancelled by squared.
5) 3√6 x 8√7 = 3 * 8 √6 * 7 = 24 √42
6) 5√3 x 6 √3 = 5 * 6 √3 * 3 = 30 √9 = 30 * 3 = 90
7) 40√30 ÷ 5√3 = (40 / 5) * (√30 /√3) = 8 * ((√3 *10) / √3) = 8 √10
8) (6√5)² = 6² * √5² = 36 * 5 = 180

Answer:

one x-intercept.

Transformation: shift to the right 8 units.

Step-by-step explanation:

The parent function is $f(t)=t^(2)$

To find the number of x-intercepts, we equate the function to zero.

$\implies t^(2)=0$

$\implies t=0$

There is only one x-intercept at t=0.

The transformed function is

$g(t)=(t-8)^2$

This function is obtained shifting the parent function 8 units to the right.

The x-intercept will now be at t=8.

Hence the image function also has one x-intercept.

Carrie pick 23 brooches of flowers From her garden each bunch had the same number of flowers after she gave 46 flowers away she had 138 left how many flowers were in each bunch.

Answers

according to question

total flowers = 23x

23x = 138 + 46 = 184
x = 8

8 flower in each bunch

hope this helps you ...

There were 6 flowers in each bunch

138÷23=6

Step-by-step explanation:

Jason hiked 15.6 kilometers on Saturday, 18.1 kilometers on Sunday,and 22.7 kilometers on Monday. How many kilometers did he hike during the three days?A. 56.1
B. 48.7
C. 52.9
D. 56.4

Answers

Answer:

The correct answer is D. 56.4

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Kilometers hiked by Jason on Saturday = 15.6

Kilometers hiked by Jason on Sunday = 18.1

Kilometers hiked by Jason on Monday = 22.7

2. How many kilometers did he hike during the three days?

Total of kilometers hiked by Jason = Kilometers hiked by Jason on Saturday + Kilometers hiked by Jason on Sunday + Kilometers hiked by Jason on Monday

Total of kilometers hiked by Jason = 15.6 + 18.1 + 22.7

Total of kilometers hiked by Jason = 56.4
