What is an equation of the line that passes through the points (-3, -2)(−3,−2) and (3, 6)(3,6)? Put your answer in fully reduced form.

Answers

Answer:

The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

m is the slope of the line whose rule is [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept, you can find it by substituting x, y in the equation by (x1, y1) OR (x2, y2)

Let us solve the question:

∵ The line passes through the points (-3, -2) and (3, 6)

∴ x1 = -3 and x2 = 3

∴ y1 = -2 and y2 = 6

→ Use the rule of m to find it

∵ [tex]m=\frac{6-(-2)}{3-(-3)}=\frac{6+2}{3+3}=\frac{8}{6}[/tex]

→ Simplify it by dividing up and down by 2

∴ m = [tex]\frac{4}{3}[/tex]

→ Substitute its value in the form of the equation above

∴ y = [tex]\frac{4}{3}[/tex] x + b

→ To find b substitute x and y by x1 and y1

∴ -2 = [tex]\frac{4}{3}[/tex] (-3) + b

∴ -2 = -4 + b

→ Add 4 to both sides

∴ -2 + 4 = -4 + 4 + b

∴ 2 = b

→ Substitute it in the form of the equation

∴ y = [tex]\frac{4}{3}[/tex] x + 2

The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Convert 50.0 mL to liters. Use the appropriate significant figures

Answers

Answer:

50 ml = 0.050 liters

Step-by-step explanation:

The solution is:

The mass/volume percent = 16/50 x 100% = 32%

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

Explanation

Given:

Mass of NaCl, m = 16.0 g

Volume of solution, v = 50.0 mL

What to find:

The mass/volume percent.

Solution

The mass/volume percent of the solution can be calculated using the formula below

The mass/volume percent  = mass/volume x 100%

so, we get,

The mass/volume percent

= 16/50 x 100%

= 32%

Hence, The mass/volume percent is 32%.

Lines ℓ and m are intersected by transversal t. ℓ ∥ m. Lines l and m are horizontal with l above m and intersected by transveral t. Angles 1, 2, 3, and 4 are formed where t intersects l with 1 and 3 above l from left to right and 2 and 4 below it. Angles 5, 6, 7, and 8 are formed where t intersects m with angles 5 and 7 above line m from left to right and 6 and 8 below it. If m∠4 = 105, what is m∠5?

Answers

Answer:

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees

Town R is 282ft + 679ft higher than Town M  = 961ft

For a certain race, 4 teams were allowed to enter 3 members each. A team earned 9 – n points whenever one of its members finished in nth place, where 1 ≤ n ≤ 8. There were no ties, disqualifications, or withdrawals. If no team earned more than 10 points, what is the least possible score a team could have earned?

A) 0

B) 1

C) 2

D) 3

E) 4

Answers

Answer:

D. 3 Points

Step-by-step explanation:

Given

[tex]Members = 3[/tex]

[tex]Point = 9 - n[/tex]

[tex]1 \leq\ n \leq 8[/tex]

Required

Determine the least possible score

The least point a member of a team can get is when n = 8.

i.e.

[tex]Point = 9 - n[/tex]

[tex]Point = 9- 8[/tex]

[tex]Point = 1[/tex]

To get the least score, each of the 3 members must have 1 point each.

So:

[tex]Total = 3 * 1[/tex]

[tex]Total = 3[/tex]

The highest temperature recorded in the town of Westgate this summer was 100°F. Last

two extremes.

Answers

Answer:

101  

Step-by-step explanation:

100- (-1) NEGATIVE MINUS NEGATIVE CANCEL OUT ON EACH OTHER AND GIVE POSITIVE: 100 + 1 = SO THE ANSWER IS  101^F

The difference between these two extreme temperatures is of

101° F.

We have the highest temperature recorded in the town of Westgate which is equal to 100°F. Last winter, the lowest temperature recorded was -1°F.

We have to find the difference between these two extremes.

What is Temperature ?

Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.

According to question, we have -

Highest temperature recorded = 100°F

Lowest temperature recorded = -1°F

Let the the difference between these two extreme temperatures be x. Then -

x = Highest temperature recorded - Lowest temperature recorded

x = 100 - (- 1) = 101° F

Hence, the difference between these two extreme temperatures is of

101° F.

Answers

Answer:

The degree of the given polynomial is 5

Step-by-step explanation:

The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.

The degree of a monomial is the sum of the exponents of the variables that appear in it.

We have the following polynomial:

[tex]3x^2y + 4xy + 1 - 5x^4y - 6y[/tex]

Degree of the first monomial: 2+1=3

Degree of the next monomial: 1+1=2

Degree of the next monomial: 0

Degree of the next monomial: 4+1=5

Degree of the next monomial: 1

Thus, the degree of the given polynomial is 5

Sarah is doing research on the average age of first-year resident physicians. She wants her estimate to be accurate to within 1 year. From past studies, she knows the population standard deviation is 8.265. How many first-year residents must she survey to be 95% confident?

Answers

Answer: The number of first-year residents she must survey to be 95% confident= 263

Step-by-step explanation:

When population standard deviation ([tex]\sigma[/tex])  is known and margin of error(E) is given, then the minimum sample size (n) is given by :-

[tex]n=(\dfrac{z^*\sigma}{E})^2[/tex], z* = Two-tailed critical value for the given confidence interval.

For 95% confidence level , z* = 1.96

As, [tex]\sigma[/tex] = 8.265, E = 1

So, [tex]n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}][/tex]

Hence, the number of first-year residents she must survey to be 95% confident= 263
