Answer:

D: (x,y) -> (2x, 2y)

Step-by-step explanation:

Take a look at the top of the roof, in the small house it is at (6,4) and in the big house it is at (12, 8).

To get from (6,4) to (12,8) you have to multiply x and y by 2.

You can test this with multiple points. Only the (x,y) -> (2x, 2y) mapping works for all of them.

Lydia is making spaghetti sauce at a community luncheon. Each batch requires 1⁄2 teaspoon of salt, 1⁄3 teaspoon of oregano, 1⁄4

Troyanec [42]

Salt is used in the largest quantity in Lydia's recipe.

Explanation

Required spices are......

Salt = $\frac{1}{2}$ teaspoon , Oregano = $\frac{1}{3}$ teaspoon, Crushed thyme = $\frac{1}{4}$ teaspoon and Black peeper = $\frac{1}{8}$ teaspoon

For finding the largest quantity, first we need to make the denominators of each fraction as equal and then identify the largest numerator.

The denominators are 2, 3, 4 and 8 and their LCM(Least common multiple) will be 24. So.....

$\frac{1}{2}= \frac{1*12}{2*12}=\frac{12}{24} \\ \\ \frac{1}{3}=\frac{1*8}{3*8}=\frac{8}{24}\\ \\ \frac{1}{4}=\frac{1*6}{4*6}=\frac{6}{24}\\ \\ \frac{1}{8}=\frac{1*3}{8*3}=\frac{3}{24}$

As the largest numerator is 12 here, so the value of $\frac{1}{2}$ is largest among all the fractions.

Thus, Salt is used in the largest quantity in Lydia's recipe.

Calculate the Laplace transforms of the following from the definition. 1. y = t^2. y = t^3

Likurg_2 [28]

Answer:

1) $L(y)=\frac{2}{s^{3}}$

2) $L(y)=\frac{6}{s^{4}}$

Step-by-step explanation:

To find : Calculate the Laplace transforms of the following from the definition ?

Solution :

We know that,

Laplace transforms of $t^n$ is given by,

$L(t^n)=\frac{n!}{s^{n+1}}$

1) $y=t^2$

Laplace of y,

$L(y)=L(t^2)$ here n=2

$L(y)=\frac{2!}{s^{2+1}}$

$L(y)=\frac{2}{s^{3}}$

2) $y=t^3$

Laplace of y,

$L(y)=L(t^3)$ here n=3

$L(y)=\frac{3!}{s^{3+1}}$

$L(y)=\frac{3\times 2}{s^{4}}$

$L(y)=\frac{6}{s^{4}}$

This table shows the number of marbles in a bag by color. If one marble is randomly selected from the bag, what is the

ratelena [41]

Answer:

p(blue or red) = 0.52 = 52%

Step-by-step explanation:

total number of marbles = 7 + 10 + 14 + 19 = 50

number of blue marbles = 7

number of red marbles = 19

number of blue or red marbles = 7 + 19 = 26

p(blue or red) = 26/50

p(blue or red) = 0.52 = 52%
