Answer:

yes (also the c.o.p would be 5)

Step-by-step explanation:

if you model this on a graph, it comes out proportional because its starts from the origin, and its a straight line with no curves.

Is 30 x 10 to the 4th power equal 3,000,000

garri49 [273]

It is not because 30×10^4 is 300,000.
The answer would then be...
30×10^5
Hope this helps!

A golf player is trying to make a hole-in-one on the miniature golf green shown.

Flauer [41]

The path of the ball is an illustration of absolute equation.

The equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

The given parameters are:

$(h,k) = (4.8,6.4)$ --- the vertex (i.e. the point where the ball hits the wall)

$(x_1,y_1) = (2,1.6)$

$(x_2,y_2) = (7.6,1.6)$

An absolute function is represented as:

$y = a |x - h| + k$

Substitute $(h,k) = (4.8,6.4)$

$y = a |x - 4.8| + 6.4$

Substitute $(x_1,y_1) = (2,1.6)$ for x and y

$1.6 = a|2 - 4.8| + 6.4$

$1.6 = a|- 2.8| + 6.4$

Remove absolute bracket

$1.6 = 2.8a + 6.4$

Collect like terms

$2.8a = -6.4+1.6$

$2.8a =- 4.8$

Solve for a

$a =-\frac{4.8}{2.8}$

Simplify

$a =-\frac{12}{7}$

Substitute $a =-\frac{12}{7}$ in $y = a |x - 4.8| + 6.4$

$y =- \frac{12}7|x- 4.8| + 6.4$

Hence, the equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

See attachment for graph that models the path

George found that he blinked 85 times in 15 minutes. At this rate, how many seconds passed during 51 blinks?

Naya [18.7K]

First convert the 15 minutes to seconds
60 sec-= 1 minute
900 sec = 15 minutes

ratio and proportion

85 blinks/900 sec= 51 blinks/ x seconds

cross multiply
85x=45900
divide by 85
x= 540 seconds
hope this helps
