6 0

we have the function

5\cos x-5=0

Rewrite

\begin{gathered} 5\cos x=5 \\ \cos x=\frac{5}{5} \\ \cos x=1 \end{gathered}

The domain for x is the given interval [0,2pi) ----> 2pi is not included

the values of x are

x=0 radians

<h2>The solution is x=0</h2>

Answer:

f\left(x\right)=x^3-6x^2+3x+10 is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

f\left(x\right)=x^3-6x^2+3x+10

As the highest power of the x-variable is 3 with the leading coefficients of 1.

  • So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

f\left(x\right)=x^3-6x^2+3x+10

0=x^3-6x^2+3x+10              ∵  f(x)=0

as

Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0

so

\left(x+1\right)\left(x-2\right)\left(x-5\right)=0    

Using the zero factor principle

if  ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0

x=-1,\:x=2,\:x=5

Therefore, the zeros of the function are:

x=-1,\:x=2,\:x=5

f\left(x\right)=x^3-6x^2+3x+10 is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.

Riley is also making boxes to hold baseballs. She wants the dimensions of her boxes
Sergio039 [100]

The volume of the box is 105 cubic units.

<h3>What is volume of cuboid ?</h3>

The amount of space inside a cuboid is calculated using the term "cuboid volume." Having length, breadth, and height, the cuboid is a three-dimensional shape. A shape with a certain length, breadth, and height will be obtained if we start with a rectangular sheet and keep stacking them. Length x Width x Height is the formula for calculating the cuboid's volume.

Given that : The dimensions of her boxes to be 4 x 6 x 3 units.

The volume of cuboid=7×5×3=105 cubic units.

so ,The volume of the box is 105 cubic units.

What is the x-intercept (-5,-5) (10,-2)
Andre45 [30]

Answer:

(20,0)

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

(-5,-5).....x1 = -5 and y1 = -5

(10,-2)...x2 = 10 and y2 = -2

slope = (-2 - (-5) / (10- (-5) = (-2 + 5) / (10 + 5) = 3/15 = 1/5

y = mx + b

slope(m) = 1/5

use either point, I will use (10,-2)...x = 10 and y = -2

now we sub

-2 = 1/5(10) + b

-2 = 2 + b

-2 - 2 = b

-4 = b

so the equation for this line is : y = 1/5x - 4

to find the x intercept, sub in 0 for y and solve for x

y = 1/5x - 4

0 = 1/5x - 4

-1/5x = -4

x = -4 * -5

x = 20.......so ur x intercept is (20,0) <====

Which equation represents a circle with a center at (-3,-5) and a radius of 6 units?
jekas [21]

Answer:

(x +3)^2 + (y + 5)^2  = 36

Step-by-step explanation:

Use general circle equation:

(x - h)^2  + (y - k)^2  = r^2

center:  (h, k)

radius : r

(x - (-3))^2 + (y - (-5))^2  = 6^2

(x +3)^2 + (y + 5)^2  = 36
