The number of times Maria drove the car on day 4 is 9 times.

A line graph is a graph that connects different data points on a graph using a straight line. A line graph is made up of a x-axis and a y-axis. In the line graph given, the number of days is on the x-axis and the number of times the car was driven is on the y-axis. A line graph is used to show quantitative data. Line graphs are used to visualise data.

In order to determine the number of times Maria drove the car on day 4, locate where day 4 is on the x-axis. Then trace 4 upward toward a data point. When the data point is located, trace it to the y-axis. When day 4 is traced to the y-axis, the value gotten is 9.

The required milliliters should be​ administered is 0.875 milliliter .

Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units or by various imperial units. The definition of length is interrelated with volume.

Given:

A​ patient's order is 70 milligrams of a drug.

Available in stock is 80 milligrams in 1 milliliter of liquid.

According to given question we have

80 milligrams = 1 milliliter

70  milligrams =1*70/80 milliliter

70  milligrams = 0.875 milliliter

Therefore, the required milliliters should be​ administered is 0.875 milliliter .

Answer:

A = 261 calories. and B = 251 calories

Step-by-step explanation:

A + 2B = 763

2A + B = 773

---------------------------

-2(A + 2B = 763)

↓

-2A - 4B = - 1526

2A + B = 773

-----------------------------

-3B = - 753

B = 753/3

B = 251

Candy bar B has 251 calories

now let's find A

A + 2B = 763

A + 2 (251) = 763

A + 502 = 763

A = 763 - 502

A = 261

Candy bar A has 261 calories

[tex]a = p(1 + in) \\ = 5500(1 + 0.048 \times 6) \\ = 7084[/tex]

The y-intercept is where the graph crosses the y-axis and is not necessarily where the maximum is. For instance, consider the graph of [tex]y=x^2 +2x+4[/tex].

The simplified radical form of the equation [tex](x^{4})^{\frac{5}{6} }[/tex] is [tex]x^{\frac{10}{3} }[/tex]

The exponentiation is written as [tex]a^{n}[/tex], where a is the base and n is the exponent or power. We say as "a by n". Exponent means the number of times the base is used as a factor.

The expression = [tex](x^{4})^{\frac{5}{6} }[/tex]

Here we have to apply the exponent rule

We know,

The power rules for the exponent [tex](a^{m})^{n}=a^{mn}[/tex]

Here multiply the exponent times the power.

Simplify it

[tex](x^{4})^{\frac{5}{6} }=(x)^{4(\frac{5}{6}) }[/tex]

=[tex]x^{\frac{20}{6} }[/tex]

Divide both 20 and 6 by 2 to make it to simplest form, then the result

=[tex]x^{\frac{10}{3} }[/tex]

Hence, the simplified radical form of the equation [tex](x^{4})^{\frac{5}{6} }[/tex] is [tex]x^{\frac{10}{3} }[/tex]

The function f(x) = cos x crosses the x-axis at x₁ = - 0.5π and x₂ = - 1.5π.

Cosine function is a function bounded between - 1 and 1 and whose period is 2π, all the values of x such that the cosine function crosses the x-axis is described by the following expression:

cos x = 0        (1)

Then, by inverse trigonometric functions:

x = cos⁻¹ 0

x = 0.5π ± π · i, where i is a non-negative integer.

If we know that i = 1 and i = 2, then the values of x within the interval [- 2π, 0] are, respectively:

u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

We are given that:

log 4 ^ u - log 8 ^ v = 1

This can also be written in another way using the logarithm properties. We get that:

u log 4 - v log 8 = 1

Subtract v log 8 from both the sides:

u log 4 = 1 + v log 8

v log 8 = u log 4 - 1

v = ( u log 4 - 1 ) / log 8

v = u log (- 4 ) - ( log 8) ⁻¹

Therefore, we get that, u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

Given that QS bisects PQR making mPQS the same as the mSQR, the numerical value of x is 4

A bisector divides a segment or angle into two equal halves.

Given the data in the question;

Since QS bisects PQR, m PQS is the same as m SQR.

Hence;

m SQR =  m PQS

We plug in the values

(4x+15) = (10x-9)

Remove parenthesis and solve for x.

4x + 15 = 10x - 9

15 + 9 = 10x - 4x

24 = 6x

x = 24/6

x = 4

Given that QS bisects PQR making mPQS the same as the mSQR, the numerical value of x is 4

The number of burgers Steve can make = 18

In this question, Steve has 6 3/4 pounds of ground beef to make hamburgers for a party.

It takes 3/8 of ground beef to make a hamburger.

We need to find the number of burgers Steve can make.

First we convert the improper fraction 6 3/4 into a proper fraction.

6 3/4 = 27/4

For 1 hamburger 3/8 of ground beef is required.

Let n be the number of burgers Steve can make.

n = (27 / 4) / (3 / 8)

n = 27/4 × 8/3

n = 9 × 2

n = 18

Therefore, the number of burgers Steve can make = 18

Sales of Statin on January 1, 2008 was 22.2 billion dollars; and the year that the Statin sales reached 25.6 billion dollars was in 2010.

Given:

S = 1.7 x + 5.2 .............................. (1)

Sales of statin on January 1, 2008 can be calculated as follows:

x = 2008 - 1998 = 10

Substituting x = 10 into equation (1), we have:

S = (1.7 * 10) + 5.2

S = 17 + 5.2

S = 22.2

The answer above implies that sales of Statin on January 1, 2008 was 22.2 billion dollars.

The year that the Statin sales reached 25.6 billion dollars can be calculated as follows:

S = 25.6

Substituting S = 25.6 into equation (1) and solving for x, we have:

25.6 = 1.7x + 5.2

25.6 - 5.2 = 1.7x

20.4  = 1.7x

x = 20.4 / 1.7

x = 12

Therefore, we have:

The year Statin sales reached 25.6 billion = 1998 + x = 1998 + 12 = 2010

The sales of Statin on January 1, 2008 is 22.2 billion dollars and the year statin sales reached 25.6 billion was in 2010

Linear functions are equations that has a leading degree of 1.

Given the expression that represents amount of sales, S , of statin (in billions of dollars) x years after January 1, 1998 as;

S = 1.7 x + 5.2

For the sales of statin on January 1, 2008, this is calculated as

x = 2008 - 1998 = 10years

Substitute x = 10 into the given equation to have;

S = 1.7(10) + 5.2

S = 17 + 5.2

S = 22.2

Therefore the sales of Statin on January 1, 2008 is 22.2 billion dollars.

For the year that the Statin sales reached 25.6 billion dollar;

S(x) = 25.6

Substituting S = 25.6 into the equation

25.6 = 1.7x + 5.2

1.7x = 25.6 - 5.2

1.7x = 20.4

x = 12

Hence the year statin sales reached 25.6 billion was in 2010
