Answer:

First, we need to set up a (y−k)^2=4p(x−h). After plugging in all of your values, you would get (x-5)^2=-4(y-1). Now, we need to solve in terms of y by dividing each side by the factors that don't contain the variable

A chemist is using 382 milliliters of a solution of acid and water. If 15.4% of the solution is acid, how many milliliters of ac
Elina [12.6K]

Answer:

58.8

Step-by-step explanation:

basic facts:

-15.4% is the same as 15.4/100

- the word 'of' in maths means times

so 15.4% of the 382ml is the same as

382*15.4/100

to do that, you multiply 382 by 15.4 = 5882.8

then you divide that by 100= 58.828

and then you just round that of to 58.8

Consider function f and function g.
ivolga24 [154]

The statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have two functions:

f(x) = lnx

g(x) = -5 lnx

The domain of the both functions x > 0

The function will be touch the y-axis when x reaches to the infinite.

The graphs of both functions have a vertical asymptote of x=0.

Unlike the graph of function f, the graph of function g decreases as x increases.

The graph of function g is the graph of function f vertically stretched by a factor of 5 and reflected over the x-axis.

Thus, the statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

GalinKa [24]

Answer:

9 cards.

Step-by-step explanation:

Given:

Yasmine needs to create invitations for the party.

She has ¾ of an hour to make the invitations.

It takes her 1/12 of an hour to make each card.

Question asked:

How many invitations can Yasmine create?

Solution:

Yasmine takes \frac{1}{12} hour create number of cards = 1

Yasmine takes 1 hour to create number of cards = \frac{1}{\frac{1}{12} }=1\div\frac{1}{12}=1\times\frac{12}{1} =12

Yasmine takes \frac{3}{4} hour to create number of cards = 12\times\frac{3}{4} =\frac{36}{4} =9

Therefore, Yasmine can create 9 cards.
