Answer:  If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23   (He will probably leave $4.25)

Step-by-step explanation: To find out the amount  of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract  12.15 - 8.46 = 12.69

To figure the tip:  .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.

Use explicit formula to find the 10th of each geometric sequence
Sindrei [870]

Answer:

1. 1*9^(10-1) = 387,420,489

2.2*4^(10-1) = 524,288

Step-by-step explanation:

The explicit formula for a geometric sequence is a1 * r^n-1

Where a1 is your first term, r is your ratio, and n is the amount of terms you want in the sequence

To solve for the 10th number in the sequence, we simply plug 10 in for n.

Hope this helps

Which graph represents the function f(x) = |x + 3|?
Sophie [7]
Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.

But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.

Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).

What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.

So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.
