This triangle is a special 45-45-90 triangle!

In a 45-45-90 triangle, to solve for the hypotenuse use the formula

[tex]h=(sidelength)*\sqrt{2}[/tex]

Here we see that 8 is being multiplied by radical 2!

We can prove that 8 is the side length by using the Pythagorean Theorem!

Answer:

the answers  is =-0

Step-by-step explanation:

is -0

p²-q²

p²-q²= (p+q)(p-q)

[by formula: (A+B)(A-B) = A²-B²]

Proof of the formula

Proof of the formula (A+B) • (A-B)

Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2

Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2

Proof of the formula (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2

Answer:what’s the question?

Step-by-step explanation:

Answer:

There is no sufficient evidence

Step-by-step explanation:

The hypothesis :

H0 : μ = 436

H1 : μ < 436

Xbar = 433

s = 23

Sample size, n = 28

The test statistic :

(xbar - μ) ÷ (s/√(n))

(433 - 436) ÷ (23/√(28))

-3 ÷ 4.3465914

Test statistic = - 0.690

The Pvalue, calculated from test statistic value, df = n - 1 = 28 - 1 = 27

Pvalue = 0.248

Pvalue > α ; Hence, we fail to reject the null and conclude that there is no sufficient evidence to support the claim that the bags are underfilled

Answer:

Translate 2 unit(s) to the right and then reflect over the x-axis

Step-by-step explanation:

You have to move the coordinates of P, Q, and R to the right by 2 so just add 2 to the x coordinate in order to to the first part of the transformation.

After that flip it so that y coordinate of the points are negative to the position they were after translating to the right.

After translating two units to the right, reflect over the x-axis.

A transformation known as a translation involves shifting each point in a figure by the same amount and in the same direction. For instance, this transformation shifts the parallelogram 3 units upward and 5 units to the right. The formula is (x, y) →(x + 5, y + 3).

Given

Simply add 2 to the x coordinate to complete the first phase of the transformation since you must move the coordinates of P, Q, and R to the right by 2.

Then reverse it so that the points' y coordinates are opposite to where they were before being translated to the right.

Answer:39.9

Step-by-step explanation:

Answer:

The third option (9+[tex]3\sqrt{7}[/tex]-[tex]3\sqrt{7}[/tex]-[tex]\sqrt{49}[/tex])

Step-by-step explanation:

With FOIL, this can be expanded. (a+b)(a-b) is equal to a²+ab-ab-b² or a²-b².

In this case, all the answers have 4 terms, so we want the first option. This makes the equation 3²+(3×[tex]\sqrt{7}[/tex])-(3×[tex]\sqrt{7}[/tex])-([tex]\sqrt{7}[/tex])².

Solving these gives 9+[tex]3\sqrt{7}[/tex]-[tex]3\sqrt{7}[/tex]-7. This is the same as  9+[tex]3\sqrt{7}[/tex]-[tex]3\sqrt{7}[/tex]-[tex]\sqrt{49}[/tex].

The equivalent expression is (c) [tex]9 - 3\sqrt 7 + 3\sqrt 7 - \sqrt {49}[/tex]

The difference of squares equation is given as:

[tex](a + b)(a - b) = a^2 -b^2[/tex]

And the radical expression is given as:

[tex] (3+ \sqrt 7)(3- \sqrt7)[/tex]

By comparing the above expression to [tex](a + b)(a - b) = a^2 -b^2[/tex], we have:

[tex]a =3[/tex]

[tex]b = \sqrt 7[/tex]

Substitute these values in [tex](a + b)(a - b) = a^2 -b^2[/tex]

[tex] (3+ \sqrt 7)(3- \sqrt7) = 3^2 - (\sqrt 7)^2[/tex]

This gives

[tex] (3+ \sqrt 7)(3- \sqrt7) = 9 - \sqrt {49}[/tex]

By complete expansion, we have:

[tex] (3+ \sqrt 7)(3- \sqrt7) = 9 - 3\sqrt 7 + 3\sqrt 7 - \sqrt {49}[/tex]

Hence, the equivalent expression is (c)

Answer:

The smallest integer is 11.

Step-by-step explanation:

Let the first integer be x.

Then the second will be (x + 1) and the third will be (x + 2).

The sum is 36. Hence:

[tex]x+(x+1)+(x+2)=36[/tex]

Solve for x:

[tex]3x+3=36[/tex]

So:

[tex]3x=33[/tex]

Hence:

[tex]x=11[/tex]

Our sequence is 11, 12, 13.

So, the smallest integer is 11.

Answer:

4/7

Step-by-step explanation:

Pr = Expected outcome/Total outcome

Since Total movies = 15

Total outcome = 15

If there are 9 actions movies

Pr(selecting the first action movie) = 9/15

Since the total remaining movies will be 14 (no replacement)

If the second movie is taken, Pr(second action movie) = 8/14 = 4/7

Answer:

4x+12+mx+3m

You use the FOIL method.

Answer:

(4+m)(x+3)

Step-by-step explanation:

x+3 is a common factor, so you can convert this to put the other 2 parts in a bracket. This results in (4+m)(x+3).

An example of how this works is if you made m=1 and x=2. This would make the original expression 4(2+3)+1(2+3), or 4×5+1×5, which is 5×5 or 25. (1+4)(2+3) also equals to 5×5.

Answer:

[tex]l=3x^2-4x+1[/tex]

Step-by-step explanation:

Given that,

The area of a rectangle is, [tex]A=3x^3+14x^2-23x+6[/tex]

The width of the rectangle, b = (x+6)

We need to find the expression for the length of the rectangle. We know that, the area of a rectangle is given by :

A = lb

Where

l is the length of the rectangle

Put all the values,

[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^3+14x^2-23x+6}{(x+6)}\\\\l=\dfrac{(x-1)(x+6)(3x-1)}{(x+6)}\\\\l=(x-1)(3x-1)\\\\=3x^2-4x+1[/tex]

So, the length of the rectangle is equal to [tex]3x^2-4x+1[/tex].

Answer:

x = 13.9

Step-by-step explanation:

Sin = Opposite over Hypotenuse

Sin(69) = 13/x

Multiply both sides by x

xsin(69) = 13

Divide both sides by sin(69)

x = 13/sin(69)

Simplify

x = 13.9 ( rounded to the nearest tenth )

Answer:

13 quarters and 24 dimes

Step-by-step explanation:

13*.25=3.25

24*.1=2.4

3.25+2.4=5.65

Answer:

yes

Step-by-step explanation:

f(x) = y = 4 - 7x/4

7x/4 + y = 4

7x/4 = 4 - y

7x = 4(4-y)

x = 4(4-y)/7 = 16/7 - 4y/7

renaming to regular function convention (with x as input variable and y as function result) :

inverse function f(x) = y = -4x/7 + 16/7 = g(x)

so, yes, they are inverses of each other.
