Is triangle ABC a right triangle?

no, because none of the slopes of the line segments forming the legs are opposite reciprocals
no, because none of the slopes of the line segments forming the legs are equal
yes, because BC is perpendicular to AC
yes, because AB is perpendicular to AC

Answer:

9 people per square mile

Step-by-step explanation:

Given that:

Area of Australia = 2.95 * 10^6 mi²

Approximate average Number of people per square mile :

This can be obtained by taking the proportion of the population of Australia and the Area of the land mass

Approximate population of Australia : 25,499,884 ( data obtained from internet)

Average number of people per square mile :

Approximate population / Land Area

25,499,884 / 2.95 * 10^6

= 8.6440284

Hence, there will be approximately 9 people per square mile.

Answer: 35 minutes

Step-by-step explanation:

For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:

= (1320 - 1040) / (9 - 2)

= 280/7

= 40 gallons per minute

Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:

= 1320 gallons + (40 × 2)

= 1320 gallons + 80 gallons

= 1400 gallons

The time taken for the pool to be completely drained will be:

= Total water in pool / Gallons drained per minute

= 1400 / 40

= 35 minutes

Answer:

TriangleJXP = Triangle HCD

Side XJ = side HC

Side CD = side JP

Side PX = HD

Step-by-step explanation:

Looking at both of the triangles you use the lines on “top” of the side. These lines represent congruence meaning that they are similar to each other.

So looking at side JP u can see that there are two lines meaning that this is the second side that is congruent to another side, side CD.

Hope this helps.

Step-by-step explanation: not sure why there is two x values can you explain more

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Answer: Choice (3) which is the sequence –2, –7, –12, ...

Here we start with -2 and subtract off 5 each time we need a new term

-2-5 = -7

-7-5 = -12

and so on.

The notation f(n+1) = f(n) - 5 tells us "subtract 5 from the nth term, called f(n), to get the next term f(n+1)"

Answer:

- 44

Step-by-step explanation:

The absolute value function always gives a positive result, that is

| - a | = | a | = a

Given

- 2 | 6x - y | ← substitute x = - 3 and y = 4

= - 2 | 6(- 3) - 4 |

= - 2 | - 18 - 4 |

= - 2 × 22

= - 44

Answer:

[tex]y=-\frac{1}{4}x+4[/tex]

Step-by-step explanation:

So we pick one point from the graph

(0, 4)

[tex]y-y_{1}=m(x-x_{1} ) \\y-4=-\frac{1}{4}(x-0)[/tex]

Answer:

[tex]y-4=-\frac{1}{4}(x)[/tex]

Step-by-step explanation:

Point slope form = y − y1 = m(x − x1)

Our point is 0,4.

So the point slope is

[tex]y-4= (slope)(x)[/tex]

The slope is -1/4.

so,

[tex]y-4=-\frac{1}{4}(x)[/tex]

This is the answer.

Answer:

[tex](x+5)+ \dfrac{2}{x+2}[/tex]

Step-by-step explanation:

Given

[tex]\dfrac{x^2+7x+12}{x+2}[/tex]

Required

Simplify and present your answer in

[tex]p(x)+\dfrac{k}{x+2}[/tex]

First, we need to expand and factorize the numerator:

[tex]\dfrac{x^2+7x+12}{x+2}[/tex]

Express 12 as 10 + 2

[tex]\dfrac{x^2+7x+10+2}{x+2}[/tex]

Split into two using brackets

[tex]\dfrac{(x^2+7x+10)+2}{x+2}[/tex]

Split to two fractions:

[tex]\dfrac{(x^2+7x+10)}{x+2}+\dfrac{2}{x+2}[/tex]

Factorize the numerator of the first fraction

[tex]\dfrac{(x^2+5x+2x+10)}{x+2}+\dfrac{2}{x+2}[/tex]

[tex]\dfrac{x(x+5)+2(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]

[tex]\dfrac{(x+2)(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]

The first fraction can be simplified to give:

[tex](x+5)+ \dfrac{2}{x+2}[/tex]

Hence, by comparison:

We have simplified the given expression to the required format of:

[tex]p(x)+\dfrac{k}{x+2}[/tex]

Which implies that:

[tex]p(x) = x + 5[/tex] and [tex]k = 2[/tex]

B (-3,0)

C (-1,1)

Step-by-step explanation:

Answer:

A missing angle in a right angle.

Step-by-step explanation:

Given, the inverse of trigonometric functions sine, cosine and tangent.

To find:

The value that can be found using the inverse trigonometric functions.

Solution:

First of all, let us consider the right angled triangle attached in answer area.

Hypotenuse is AC, Base is BC and AB is the Altitude/Height of the right angled [tex]\triangle ABC[/tex].

Let us suppose all three sides are known and [tex]\angle C[/tex] is unknown.

Formula:

[tex]1.\ sin\theta = \dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]2.\ cos\theta = \dfrac{Base}{Hypotenuse}[/tex]

[tex]3.\ tan\theta = \dfrac{Perpendicular}{Base}[/tex]

Let us consider [tex]\angle C[/tex].

[tex]sin C = \dfrac{AB}{BC}[/tex]

If we taken inverse:

[tex]sin^{-1} sinC = sin^{-1} (\frac{AB}{BC})[/tex]

[tex]\Rightarrow \angle C = sin^1\frac{AB}{BC}[/tex]

Similar is the case for cosine and tangent.

Therefore, the missing angle of the right angled triangle can be calculated by the inverse of sine, cosine and tangent.

hope that helps!

Answer:

d=2/5 or d=2

Step-by-step explanation:

Step 1: Subtract -6d^2 from both sides.

−d2−12d+4−−6d2=−6d2−−6d2

5d2−12d+4=0

Step 2: Factor left side of equation.

(5d−2)(d−2)=0

Step 3: Set factors equal to 0.

5d−2=0 or d−2=0

d= 2/5 or d=2

Answer:

12, 17, 24

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is

T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12

T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17

T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
