Paul [167]2 years ago
4 0

Step-by-step explanation:

Violet bought 120 at "3 for $2".

how many groups of 3 did she buy ?

120/3 = 40 groups of 3.

so, she paid 40×2 = $80.

Harry bought 120 at "6 for $5".

how many groups of 6 did he buy ?

120/6 = 20 groups of 6.

so, he paid 20×5 = $100.

that means Violet paid 100 - 80 = $20 less than Harry.

Answer:

(a) y = ¼ sin(x² + C)

(b) y = ¼ sin(x²)

Step-by-step explanation:

(a) dy/dx = ½ x √(1 − 16y²)

dy / √(1 − 16y²) = ½ x dx

4 dy / √(1 − 16y²) = 2x dx

sin⁻¹(4y) = x² + C

4y = sin(x² + C)

y = ¼ sin(x² + C)

(b) When x=0, y=0.

0 = ¼ sin(C)

C = 0

y = ¼ sin(x²)

consider the polynomial 6x^4+24x^3-72x^2. what is the greatest common factor of the terms of the polynomial
mash [69]

First, look at the coefficients, 6, 24, -72. 6 is a factor of 6, 24, and -72. Since one of the coefficients is in fact 6, then 6 is the GCF of the coefficinets.

Now look at the variables. You have x^4, x^3, and x^2. Remember what the exponents mean. They mean a multiplication of several factors of x.

x^4, x^3, x^2 mean xxxx, xxx, xx

xxxx, xxx, xx have 2 factors of x in common, so the greatest common factor of the variables is xx which is the same as x^2.

When you put together the common factor of the coefficients and the common factor of the variable parts, you get GCF = 6x^2.
