Answer:

∠U = 56.4

Step-by-step explanation:

We can use trigonometric functions to solve this

Here we are given the opposite side of ∠U as well as the adjacent side.

When dealing with the adjacent and opposite side we use sin

Sin = Opposite side / Adjacent side

Opp = 5 and adj = 6

Sin(U) = 5/6

* take the inverse sine of both sides *

arc(sin)(u) = u

arcsin(5/6) = 56.4 *( rounded to the nearest tenth )

∠U = 56.4

What is the y-intercept of the graph of the function f(x) = x^2 + 3x + 5?

Semenov [28]

Answer:

(0,5)

Step-by-step explanation:

To find the y-intercept, substitute in 0 for x and solve for y.

y=x^2 + 3x + 5

y=(0)^2 + 3(0) +5

y=0+0+5

y=5

Since there is no x coordinate for a y-intercept, the answer is (0,5)

On story Ratios Worksheet 3: how do you do this problem. Jackie sold lemonade and made $24 while Liana sold lemonade and made $3

Drupady [299]

Answer:

Ratios of money made by Jackie and Liana = $\frac{2}{3}$

Step-by-step explanation:

We have given,

On selling a lemonade :

Money made by Jackie = $24

Money made by Liana = $36

We need to find the ratios of money made by Jackie and Liana by selling lemonade.

So, Ratio = Money made by Jackie / Money made by Liana

or , Ratio = $\frac{24}{36}$

or, Ratio = $\frac{2}{3}$

So, the ratios of money made by Jackie and Liana is $\frac{2}{3}$

For the data in the table tell whether y varies directly with X if it does write an equation for the direct variation

frozen [14]

a) Option B Direct variation, y=1.8x is correct option.

b) Option A Not a direct variation is correct option.

Step-by-step explanation:

a) for the data in the table tell whether y varies directly with X if it does write an equation for the direct variation

The direct variation is represented by:

$y=kx \,\,or\\\frac{y}{x}=k$

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

$\frac{5.4}{3}=1.8\\\frac{12.6}{7}=1.8\\\frac{21.6}{12}=1.8$

Since value of k is constant i.e 1.8 so, y varies directly with x.

Option B Direct variation, y=1.8x is correct option.

b) For the data in the table tell whether Y varies directly with x if it does write an equation for the direct variation.

The direct variation is represented by:

$y=kx \,\,or\\\frac{y}{x}=k$

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

$\frac{1}{-2}=-\frac{1}{2}\\\frac{6}{3}=2\\\frac{11}{8}=1.3$

Since value of k is not constant so, y doesn't varies directly with x.

Option A Not a direct variation is correct option.

The sum of two numbers is -36. Their difference is 68

trasher [3.6K]

Answer:

Step-by-step explanation:

Let the numbers be x and y

x + y = -36........(1)

x - y = 68..........(2)

Adding (1) and (2)

2x = 32

x = 32/2

x = 16

And x + y = -36....(1)

16 + y = -36

y = -36 - 16

y = -52

The number are 16 and -52
