Answer:

What number, when added to negative four is equal to negative five.

Step-by-step explanation:

Rearange the numbers to get -4+g=-5.

This eqation now reads -4 plus a number g is equal to -5, and can also be read as what number (g) added to -4 = -5.

If we were to solve for g we would get g= -1.

Hope this helps!

G=-1          so

Answer:

Length = 30 inches

Width = 24 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Perimeter of a rectangle (P) = 2 width + 2 length

Since:

Length (L) = width (w) + 6

Replacing with the values given:

108 = 2w+2 (w+6)

Solving for w:

108 = 2w+2w+12

108-12 =2w+2w

96 =4w

96/4 =w

w= 24 in

Replacing w in the length formula:

L = w+6

L= 24+6 = 30in

Step-by-step explanation:

Answer:

a) sec (θ -π/2) =  co secθ

b) [tex]sin(\frac{\pi }{18} ) cos (\frac{\pi }{9})+ cos(\frac{\pi }{18} ) sin (\frac{\pi }{9} )=\frac{1}{2}[/tex]

Step-by-step explanation:

a)

sec (θ -π/2) = sec(π/2 -θ) = co secθ

b)

we will use formula

sin A cos B + Cos A sin B = sin(A+B)

Given [tex]sin(\frac{\pi }{18} ) cos (\frac{\pi }{9})+ cos(\frac{\pi }{18} ) sin (\frac{\pi }{9} )[/tex]

                                                =  [tex]Sin(\frac{\pi }{18} +\frac{\pi }{9} )[/tex]

                                                = [tex]sin(\frac{\pi+2\pi }{18} ) = sin(\frac{3\pi }{18})[/tex]

                                                = [tex]sin(\frac{\pi }{6})[/tex]

Answer:

B

Step-by-step explanation:

just took the test on edge

By using the given information, the period particularly, we conclude that the function is y = sin(3x).

First, we know that:

With these 3 considerations, we know that the function is something like:

y = sin(k*x)

So we only need to find the value of k.

We also know that the period of the function is: (2/3)*pi

This means that:

sin(k*(x + (2/3)*pi) = sin(k*x)

Remember that the period of the sine function is 2pi, then:

k*(2/3)*pi = 2pi

k/3 = 1

k = 3

Then the function is:

y = sin(3x).

Step-by-step explanation:

Congruent corresponding angle makes triangle similar. For triangles to be congruent both the corresponding angles and the corresponding sides must be congruent.

Answer:

yes, the corner is at a 90 angle

Step-by-step explanation:

Answer:

It is a right triangle.

Step-by-step explanation:

We know that 5, 4 and 3 is a Pythagorean Triple. In this instance, however, the Hypoteneus is 50, with the other sides being 40 and 30. This is simply the Pythagorean triple but ×10 larger.

You can also check this by:

50²= 30²+40²

---------------------------------------

Therefore, if the side-lengths is a Pythagorean triple, then the figure is a right triangle.

==========================================

Explanation:

C and D are inverses of each other. When they multiply together, they will produce the identity matrix I

C*D = I

D*C = I

note: this is the uppercase letter 'i' and not the number one. The 'i' stands for 'identity'. Another thing to note is that matrix multiplication is not normally commutative, but it works for matrix inverses.

--------------------

So this means C*D*D = (C*D)*D = (I)*D = I*D = D because multiplying the identity matrix with some matrix X leads to the same matrix X.

This is why the first choice is the answer.

The second choice doesn't work because C*C*D = C*(C*D) = C*(I) = C*I = C

The third choice doesn't work because we don't have any C's here. All we can say is that D*D*D = D^3

Similarly choice 4 doesn't work as all we can say is C*C*C = C^3.

Step-by-step explanation:

an = 56-8(n-1)

The region of integration in the xy-plane for the given integral ∫∫R √(4xy) dy dx, where R is the region bounded by x = 0, x = -3, y = 0, and y = -9 - x^2, can be visualized as a triangular region in the first quadrant.

The given integral is a double integral of the function √(4xy) over a specific region in the xy-plane. To determine the region of integration, we consider the given bounds: x ranges from 0 to -3, and y ranges from 0 to -9 - x^2.

Starting with the x bounds, x = 0 represents the y-axis, while x = -3 represents a vertical line passing through the point (-3, 0). Thus, the region is bounded by the y-axis on the left and the vertical line x = -3 on the right.

Moving on to the y bounds, y = 0 represents the x-axis, while y = -9 - x^2 represents a downward-opening parabola with its vertex at the origin and its axis of symmetry parallel to the y-axis. Since y is negative, the parabola lies below the x-axis.

By combining the x and y bounds, we obtain a triangular region in the first quadrant. The triangle is formed by the x-axis, the line x = -3, and the curve y = -9 - x^2. This region of integration represents the area over which the function √(4xy) is being integrated.

Answer:

12 = k

Step-by-step explanation:

Begin: 27.5 = 3 + 5 (k-9.5)

1. Always begin with the parenthesis, which is 5(k-9.5), which comes out to be 5k - 47.5 since the 5 must be multiplied by the k and the -9.5.

Now: 27.5 = 3 + 5k - 47.5

2. Combine the 3 and -47.5, which comes to be -44.5

Now: 27.5 = -44.5 + 5k

3. Add 44.5 to both sides, to make the right side have only the 5k, and the left side to have 72

27.5 + 44.5 = -44.5 + 44.5 + 5k

Now: 72 = 5k

4. Divide both sides by 5 to be left with just what k equals

72/5 = 5k/5

Final Answer: 12 = k

Answer:

Domain: -4 < x < 4

Zeros: (-2, 0), (0, 0) and (2, 0)

The function is positive if: 0 < x < 2

The function is negative if: -4 < x < 0 and 2 < x < 4

Step-by-step explanation:

Domain of the function are those x values where the function is defined, For this case, -4 < x < 4

Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)

The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)

The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)
