Answer:

-c is the blank and a+b is variables of real numbers.

Step-by-step explanation:

A real number is a value of a continuous quantity that can represent a distance.

However equality is a relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object.

= Obtuse triangle

 (a triangle in which one of the interior angles measures more than 90° degrees.)

Answer:

-1

Step-by-step explanation:

so firstly we solve by integrating by parts.

lnX × X - the integral of x/x

so the integral is Xln(X) - X

so the value should converge at -1

Answer: Your answer is X=-63

Hope this helps!

Answer:

$253.5

Step-by-step explanation:

195 x .3 = 58.5

58.5 + 195 = $253.5

Answer:

A. in Step 3

Step-by-step explanation:

It is factored correctly. Then separated into two smaller equations correctly. But in solving x + 10 = 0, there is an error.

x + 10 = 0

Add -10 to both sides.

x = -10

So, the error is in step 3.

Answer:

A . In Step 3.

Step-by-step explanation:

In step 3 the student went wrong

x = 4 or x = -10 is correct

( if x + 10 = 0, then x = -10)

AE= 17.4 to nearest tenth

Step-by-step explanation:

Opposite + hypotenuse = SOH / sin

Sin 31 = 6/h

xh, then ÷ sin31

H= 6/sin31

H= 11.649....(a or b & 6 being a or b)

a^2 + b^2 = c^2

c = 13.1

Actually it's not a right-angle triangle

180 - 13+31 (or 44) = 136 degrees

Cosine rule: a^2=b^2+c^2 - 2bc cosA

AE = root 11.649...^2 + 7^2 - 2x11.649...x7xcos136

= 17.3791......

AE= 17.4 to nearest tenth

Answer:

8. Joel will not form a right triangle.

9.20 minutes

Step-by-step explanation:

8. First use theorem

Right triangle theorem

c²=a²+b²

c=20 ft

a=8ft

b=15 ft

20² =8²+15²

simplify

400= 64+225

400 does not = 289

9.

Part B)

if Joel cut the longest piece of fencing in order to make a right triangle

longest part is 17^2

a²+b²=289

c²=√289

c=17 ft

the perimeter of the fence is

a+b+c

17+8+15

perimeter is

40 ft

Answer:

F(5)=11.25

Step-by-step explanation:

I'm like 80% sure this is right, and I hope it helps.

First I did 9/4 which equals 2.25. and that would be F(1)

then added 2.25 to 9 which equals 11.25

multiplying 2.25 by 5 would also equal 11.25.

I did 5 because, on a number line, 5 comes after 4.

Note that √((1 - x)/x) is defined only as long as 0 < x ≤ 1.

Consider a right triangle with reference angle θ such that

[tex]\cot(\theta) = \sqrt{\dfrac{1-x}x}[/tex]

In other words, on an appropriate domain,

[tex]\theta = \cot^{-1}\left(\sqrt{\dfrac{1-x}x}\right)[/tex]

In such a triangle, you would find that

[tex]\sin(\theta) = \sqrt x[/tex]

so f(x) reduces a bit to

[tex]f(x) = \cos\left(2 \tan^{-1}(\sqrt x)\right)[/tex]

Now consider another triangle with reference angle ɸ such that

[tex]\tan(\phi) = \sqrt x \implies \phi = \tan^{-1}(\sqrt x)[/tex]

In this triangle, you would find

[tex]\cos(\phi) = \dfrac1{\sqrt{1+x}}[/tex]

Recalling the double angle identity for cosine, it follows that

[tex]f(x) = \cos(2\phi) = 2 \cos^2(\phi) - 1 = \dfrac{1-x}{1+x}[/tex]

Differentiating with respect to x yields

[tex]f'(x) = -\dfrac2{(1+x)^2}[/tex]

while

[tex]f(x)^2 = \dfrac{(1-x)^2}{(1+x)^2}[/tex]

It follows that

[tex]f'(x)(x-1)^2 - 2f(x)^2 = 0[/tex]

so B is the correct choice.

I think it would be 9 meters.

Step-by-step explanation:

5x2=10

28-10=18

18(divided by)2=9 meters

Answer:

9 meters long

Step-by-step explanation:

the perimeter is 28 meters. itts 5 meters wide and itt is recttangle so itt have two of the same width. so now 5x2=10 and 28-10=18 now 18/2=9. please mark me brainliest if i got it correct

Step-by-step explanation:

You know that the three lines are parallel.

There weren't really any specific instructions so I'd assume that we're trying to find the lines. They are all in the same thing, as shown, one is 21 and the other is 12. That means the parallel line is cutting of 9.

We can then assume 2x+2-9=x+3

Then, to solve, you can get 2x-7=x+3

X=10

Answer:

C. 28

Step-by-step explanation:

According to the provided figure :

The measure of the angle EFG equal to the measure of the angle EFH

Which means 2(x + 2) = 60

2(x + 2) = 60

Then

2x + 4 = 60

Then

2x = 60 - 4

Then

2x = 56

Then

x = 56/2

Then

x = 28

Answer:

38.6 in^2

Step-by-step explanation:

Find the third side using law of cosines

11.1^2 + 7^2 - 2(11.1)(7)cos 84   = x^2

  x = 12.49

semi perimeter =  (11.1 + 7 + 12.49)/2 = 15.29

Heron's formula for triangle area with 3 side lengths given

sqrt( ( 15.29)(15.29-11.1)(15.29-7)(15.29-12.49) ) = 38.56 in^2
