Answer:

41°

Step-by-step explanation:

∠C is opposite of side c.

Using law of cosines:

c² = a² + b² − 2ab cos C

17.2² = 26² + 19² − 2(26)(19) cos C

cos C = 0.750

C ≈ 41°

Answer:

The answer is 41 degrees

Plug values in function.

f(3) = 0.01(2)(3)

f(3) = 0.06

f(5) = 0.01(2)(5)

f(5) = 0.10

Average rate of change formula: f(b) - f(a) / b - a

Plug in.

0.10 - 0.06 / 5 - 3 = 0.04 / 2 = 0.02

Average rate of change: 0.02

Answer:

The Average rate of change: 0.02

Step-by-step explanation:

Great Question, First to be able to figure out the average rate of change for the function we need to plug each value for x given into the function and get an output value

[tex]f(3) = 0.01(2)(3)[/tex]

[tex]f(3) = 0.06[/tex]

[tex]f(15) = 0.01(2)(15)[/tex]

[tex]f(15) = 0.3[/tex]

Now that we have both outputs for the values of x given to us in the question, we can use the rate of change formula from the picture below to find the Rate of Change of these two values of x.

[tex]\frac{0.3-0.06}{15-3} = r[/tex]

[tex]\frac{0.24}{12} = r[/tex]

[tex]0.02 = r[/tex]

So Now we see that The Average rate of change: 0.02

Answer:

(-5, 1)

Step-by-step explanation:

We are given a kite on the graph which is rotated 180° clockwise about the origin and then reflected over the Y axis followed by reflection over the X axis.

We are to find the coordinates of point A after the complete transformation.

A (-5, 1)

When a point is rotated 180° clockwise about the origin, the signs of its coordinates change.

A (-5, 1) ---> A' (5, -1) - after clockwise rotation of 180 degrees about origin

Then this point A' is reflected over the Y axis where the y coordinate remains the same but x coordinate changes its sign.

A' (5, -1) ---> A'' (-5, -1) - after reflection through y axis

Now this point A'' is reflected over the X axis where the x coordinate remains the same while y coordinates changes its sign.

A'' (-5, -1) ---> A''' (-5, 1) - after complete transformation

Step-by-step explanation:

4x-2=x+28

-x -x

3x-2=28

+2 +2

3x=30

3x/3 = 30/3

x=10

The value of x for which DEFG must be a parallelogram is Option(B) 10 .

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

As we know that for a parallelogram, the opposite adjacent sides are always parallel and equal in length.

Therefore, for DEFG to be a parallelogram, the sides DH and FH must be equal in length.

We have,  DH = FH

⇒ 4x - 2 = x + 28

⇒ 3x = 30

∴  x = 10

Thus, the value of x for which DEFG must be a parallelogram is Option(B) 10 .

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation. Many professionals use equations every day, including air traffic controllers, architects, computer programmers and carpenters.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Equation is defined as the state of being equal and is often shown as a math expression with equal values on either side, or refers to a problem where many things need to be taken into account. An example of an equation is 2+2 = 3+1.

Answer:

False.

Because Only one circle can be circumscribed about a given triangle.

Final answer:

The statement that many triangular shapes can be circumscribed about a given circle is true, as an infinite number of triangles can be formed by connecting any three distinct points on the circumference of the circle.

Explanation:

The statement "Many triangular shapes can be circumscribed about a given circle" is true. By definition, a circumscribed triangle is one that surrounds a circle, touching the circle exactly at its perimeter at three points.

Given a circle, you can indeed construct infinite triangles that circumscribe the circle, as for any set of three points on the circumference of the circle, a unique triangle can be formed.

In mathematical terms, three points determine one of these curves; that is, through any three points not in a straight line on a circle's circumference, we can draw a unique triangle which will circumscribe the circle.

Since there are an infinite number of points on a circle's circumference, we can choose an infinite number of triplets of points, each producing a different circumscribed triangle.

Answer:

Part 5) The roots are x=-3 and x=1.5

Part 6) The solution on a number line is the shading area below of the line y=-1/3 (close circle)

Step-by-step explanation:

Part 5) Find the roots of the parabola given by the following equation

[tex]2x^{2} +5x-9=2x[/tex]

we know that

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]2x^{2}+5x-2x-9=0[/tex]

[tex]2x^{2}+3x-9=0[/tex]

so

[tex]a=2\\b=3\\c=-9[/tex]

substitute in the formula

[tex]x=\frac{-3(+/-)\sqrt{3^{2}-4(2)(-9)}} {2(2)}[/tex]

[tex]x=\frac{-3(+/-)\sqrt{81}} {4}[/tex]

[tex]x=\frac{-3(+/-)9} {4}[/tex]

[tex]x=\frac{-3(+)9} {4}=1.5[/tex]

[tex]x=\frac{-3(-)9} {4}=-3[/tex]

therefore

The roots are x=-3 and x=1.5

Part 6) Solve the inequality and graph the solution on a number line.

[tex]-3(5y-4)\geq 17[/tex]

Solve for y

[tex]-15y+12\geq 17[/tex]

Subtract 12 both sides

[tex]-15y\geq 17-12[/tex]

[tex]-15y\geq 5[/tex]

Multiply by -1 both sides

[tex]15y\leq -5[/tex]

Divide by 15 both sides

[tex]y\leq -1/3[/tex]

The solution is the interval -----> (-∞, -1/3]

All  real numbers less than or equal to negative one third

The solution on a number line is the shading area below of the line y=-1/3 (close circle)

The graph in the attached figure

The center of the circle is (-3, -9/2) and the radius is sqrt(41)/2.

To find the coordinates of the center and length of the radius of the circle, we need to rewrite the equation of the circle in the standard form (x-h)^2 + (y-k)^2 = r^2. First, complete the square for the x and y terms by adding and subtracting the necessary constants:

x^2 + 6x + 4y = 23

x^2 + 6x + 9 + 4y + 9 = 23 + 9 + 9

(x + 3)^2 + (y + 9/2) = 41/4

Therefore, the center of the circle is (-3, -9/2) and the radius is sqrt(41/4), which simplifies to sqrt(41)/2.

Answer:

x = -4, 10

Step-by-step explanation:

We take the square root and use the fact of "plus-minus" and find two values of x. The process of solving this equation is shown below:

[tex](x-3)^2 = 49\\\sqrt{(x-3)^2}=\sqrt{49}\\  x-3=+-7\\x=3+7=10\\x=3-7=-4[/tex]

Hence the two values of x are -4 and 10

Note: both (-7)^2 and (7)^2 are 49 . So we took "plus-minus" values of [tex]\sqrt{49}[/tex]

Answer: -4 and 10

Step-by-step explanation:
