Given the relation y = 7x2 + 3, if the input is 4, what is the output? (4 points)

aivan3 [116]

I'm assuming that you meant:
y = 7x² + 3

Remember! Inputs are always x values (unless stated otherwise). Meaning the problem says:
x = 4

y = 7(4)² + 3

The square only applies to the 4. The 7 is not going to be squared! (To be exact it only applies to whatever the value of x is.

4² = 4·4 = 16

Remember:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Follow PEMDAS from left to right (or in the case above from top to bottom).

7·16 + 3 = ?

16·7 = 10·7 + 6·7 = 70 + 42 = 112
(All I did to multiply was break it up into parts. If it confuses you don't worry about it, and just multiply it out like normal or use a calculator if you are allowed to)

112 + 3 = ?

Our output is:
115!

Farhan orders one plate of seafood fried rice at a restaurant which offers at 25% discount. the Marked price of the seafood frie

ANTONII [103]

Answer:

The total amount of money he has to pay for the dish is $8.3861.

Step-by-step explanation:

Here, the marked price of the seafood fried rice = $9.50

Now, discount on the marked price = 25%

Calculating 25% of $9.50 = $\frac{25}{100} \times 9.50 = 2.375$

So, the discount offered = $2.375

Now, the Selling Price of dish = Marked Price - Discount

= $9.50 - $2.375 = $7.125

Now, here the service charge applied here = 10%

Calculating 10% of $7.125 = $\frac{10}{100} \times 7.125 = 0.7125$

So, the service charge applied = $0.7125

So, the new Selling Price of dish = Selling Price + Service Charge

= $7.125 + $0.7125 = $7.8375

Again, here the GST applied here = 7%

Calculating 7% of $7.8375 = $\frac{7}{100} \times 7.8375 = 0.5486$

So, the GST applied = $0.5486

So, the new Selling Price of dish = Selling Price + GST

= $7.8375 + $0.5486 = $8.3861

Hence, the total amount of money he has to pay for the dish is $8.3861.

Here's the result of this question

Marysya12 [62]

Answer:

B) Its final coordinates are (8,-6)

Step-by-step explanation:

1. Translated 1 unit up and 4 units left

(-2,7) becomes (-6, 8)

2. Reflected about the x-axis

(-6,8) becomes (-6, -8)

3. Rotated 90° anticlockwise about the origin

(-6, -8) becomes (8, -6) because when rotating 90 degrees anticlockwise about the origin, point A (x,y) becomes point A' (-y,x). In other words, switch the x and y and make y negative.
