45 45 90
This question is using the 45 45 90 rule can someone help

Answer:

  D.  81/m^7

Step-by-step explanation:

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

Using these, your expression simplifies to ...

  [tex](3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}[/tex]

Answer:

The median dr smith is 15

Step-by-step explanation:

The answer is either

A (-4,4)

B [-4,4)

C (-4,4]

D [-4,4]  

Step-by-step explanation:

First of all this is a function which means it has a graph and a question with it. Concluding by that there should be a fraction chance for each answer, and seeing that there's 4 answers it is 1/4 chance per each. Concluding by all of this, choose one of them and it should be a 1/4 chance it is correct.

The solution to a system of linear equations is (0, 4). One of the linear equations in the system is y = 8.1 +4.the answer is 12.1

Answer:

d yess i think it is if right mark branly pleasee

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Slope=rise over run.

From bottom marked point (-3, -3) to the other (-2, 1)...

Rise= 4

Run= 1

4/1=4

Therefore, the slope is 4.

Hope this helps!! Have an amazing day ❤

Answer:

part a is 54            part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2  

so the top and bottom of the rectangle are 99 and both sides are 88

A.

[tex]3 = a \times b { }^{0} [/tex]

when it's to the 0 power it equals 1

[tex]b {}^{0} = 1[/tex]

[tex]3 = a \times 1 [/tex]

so therefore a=3

_______________

[tex]75 = a \times b {}^{2} [/tex]

replace a with 3

[tex]75 = 3 \times b {}^{2} [/tex]

divide 75 by 3 equalling 25

[tex]b {}^{2} = 25[/tex]

lastly find the square root

[tex] \sqrt{25} = 5[/tex]

there fore

Answer:

  a) (a, b) = (3, 5) or (3, -5)

  b) (a, b) = (2, 3)

Step-by-step explanation:

Generally, you solve systems like this by dividing one equation by the other. This gives you the value of the base (b). Substituting that into either equation gives you the scale factor (a).

__

a) Since b^0 = 1, you already have the solution for 'a': 3 = a. Substituting that into the second equation gives ...

  75 = 3b^2

  b = √(75/3) = √25 = 5

Since both exponents of b are even, there is no reason why b could not be -5.

Possible solutions: (a, b) = (3, 5) or (3, -5).

__

b) Dividing the second equation by the first gives b:

  [tex]\dfrac{54}{18}=\dfrac{a\cdot b^3}{a\cdot b^2}\\\\3=b \qquad\text{simplified}\\\\18=a\cdot3^2\qquad\text{substitute for b}\\\\\dfrac{18}{9}=a=2\qquad\text{divide by 9}[/tex]

The solution is (a, b) = (2, 3).

Additional comment

Usually, we're only interested in positive solutions for 'b'. Negative values usually only make sense when the exponent is an integer, as in the case of an exponential sequence.

Answer:

A

Step-by-step explanation:

sin 214 = -0.5591

tan 214 = 0.6745

cos 214 = -0.8290

The correct statement about 214 degrees angle is sin 214 < 0 because sin 214 = -0.5591 and -0.5591 < 0 is true option (A) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have statements:

sin 214 < 0

tan 214 < 0

cos 214 > 0

As we have given trigonometric ratio,

The trigonometric ratio can be defined as the ratio of the pair of a right-angled triangle.

From the trigonometric table:

sin 214 = -0.5591

tan 214 = 0.6745

cos 214 = -0.8290

Plug the above values in the inequality:

-0.5591 < 0 (true)

0.6745 < 0 (false)

-0.8290 > 0 (false)

Thus, the correct statement about 214 degrees angle is sin 214 < 0 because sin 214 = -0.5591 and -0.5591 < 0 is true option (A) is correct.

Explanation:

This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.

The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.

Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.
