The measure of an angle is 149°. What is the measure of its supplementary angle?

Answer:

Step-by-step explanation:

0.31=0.3100

0.409=0.4090

0.414=0.4140

0.4186

arranging smallest to largest

0.3100,0.4090,0.4140,0.4186

or 0.31,0.409,0.414,0.4186

The expanded form representation of the decimal number given as in the task content is; (8×10) + (0×1) +(1 ×0.1) +(0×0.01) + (6×0.001).

It follows from the task content that the number given is; 80.106.

Hence, the expanded form is;

(8×10) + (0×1) +(1 ×0.1) +(0×0.01) + (6×0.001)

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

Answer:

y =0.25(x-4 )^{2}-1

Step-by-step explanation:

The formula of vertex form is as follows:

Y = a(x-h)^2+k

h = the x value for the vertex (in this case it is 4)

k = the y value for the vertex (in this case it is -1)

If you input these into the equation you are left with:

Y = a(x-4)^2-1

To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)

I hope this was able to help! ^_^

Answer:

[tex]M=(\frac{3}2},\frac{9}{2})[/tex]

Step-by-step explanation:

The midpoint is given by the formula:

[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

So we have the two endpoints A(3,7) and B(0,2).

Let's let (3,7) be x₁ and y₁ and let's let (0,2) be x₂ and y₂.

Therefore, our midpoint is:

[tex]M=(\frac{3+0}{2},\frac{7+2}{2})[/tex]

Add:

[tex]M=(\frac{3}2},\frac{9}{2})[/tex]

Or:

[tex]M=(1.5,4.5)[/tex]

And we're done!

Hope this helps!

Answer: (1.5,4.5)

Step-by-step explanation:

For midpoint i have a little cheer to remember the steps it goes," Midpoint, midpoint, what do you do? add them together and divide by two.

so using this problem as an example you would add the y coordinates and the x coordinates and get (3,9) then you divide X and Y by two.

So 3 divided by 2 is 1.5 so that is the X coordinate for the midpoint

and 9 divided by 2 is 4.5 so that is your Y coordinate for the midpoint.

Put it together and your answer is (3.5,4.5)

Answer:

9

Step-by-step explanation:

two negatives make a positve

Answer:

-9

Step-by-step explanation:

Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

Answer:

[tex]x\geq -4[/tex]

Step-by-step explanation:

So we have the inequality:

[tex]3(x+6)-2(x+2)\geq 10[/tex]

First, distribute:

[tex](3x+18)+(-2x-4)\geq 10[/tex]

Combine like terms:

[tex](3x-2x)+(18-4)\geq 10[/tex]

Add:

[tex]x+14\geq 10[/tex]

Subtract 22 from both sides:

[tex]x\geq -4[/tex]

And we're done!

Answer: −1−3k

Step-by-step explanation:

Distribute:

(−3+4k)−1(−2+7k)

(-3+4k)+{2-7k}

Eliminate redundant parentheses:

(−3+4k)+2−7k

-3+4k+2-7k

Add the numbers:

−3+4k+2−7k

−1+4k−7k

Add the same term to both sides of the equation:

−1+4k−7k

−1−3k

Answer: 60 feet

Step-by-step explanation:

Fron the question, we have been told to use a scale factor of 1 inch:12 feet. This simply means that 1 inch has been represented to 12 feet of the actual dimension.

We are further told that a plastic toy bird has a wingspan of 5 inches. The actual bird wingspan will therefore be 5 multiplied by 12 feet and this will be:

= 5 × 12 feet

= 60 feet

A plastic toy bird that has a wingspan of 5 inches has an actual bird wingspan of 60 feet

Answer:

Function is a reflection and dilation of function f.

Step-by-step explanation:

A reflection gives the mirror image of function.

A function can be reflected about an axis by multiplying by -1.

To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).

The correct option is: B. Function h is a reflection and a dilation of function f.

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

The functions are:

[tex]f(x) = 2^x[/tex]

[tex]g(x) = -3 \times 2^x[/tex]

It can be seed that g is f multiplied by -3.

In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.

Thus, the correct answer is:

B. Function h is a reflection and a dilation of function f.

Answer:

mass of copper in the resulting mixture = 104 grams of pure copper

Percent of the resulting mixture that is copper = 81.25%

Step-by-step explanation:

The complete question is

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper. How many grams of copper are in the resulting mixture? What percent of the resulting mixture is copper?

The original alloy has a mass of 50 grams,

52% of this 50 grams is copper,

mass of copper = 0.52 x 50 = 26 grams

78 grams of pure copper added will bring the mass of copper to..

mass of copper = 26 + 78 = 104 grams of pure copper

After adding 78 grams of copper to the alloy, the resultant mass of the mixture will be = original mass of alloy + mass of the pure copper added

==> 50 + 78 = 128 grams

Percentage of the resulting mixture that is copper = (total mass of copper in the mixture/total mass of mixture x 100%)

==> 104/128 x 100% = 81.25%

Answer:

M = (1.5, 2.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Here (x₁, y₁ ) = C(4, 6) and (x₂, y₂ ) = D(- 1, - 1) , thus

midpoint = [ [tex]\frac{1}{2}[/tex] (4 - 1) , [tex]\frac{1}{2}[/tex] (6 - 1 ) ] = (0.5(3), 0.5(5) ) = (1.5, 2.5 )
