Step-by-step explanation:

I think the people who just spam questions are just lazy and they have nothing else to do with their lives. So they try to make themselves feel better by annoying other people. I hope you are having a good day other than people spamming questions!

Answer:

No

Step-by-step explanation:

To make this simpler, we will round each number. 917 rounds to 900 and 33 rounds to 30. 900 * 30 = 27,000. We can do this in our head because 9 * 3 = 27, and there are three zeros total between 900 and 30, so we add three zeros after 27. 2750 is not a reasonable answer because the true answer is about 10 times greater than 2750.

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\frac{3 +NZ}{3}[/tex] = [tex]\frac{5+5}{5}[/tex]  ⇒  NZ = 3

XZ = 6 × 2 = 12

The length of NZ = 3 units.

The length of XZ = 12 units

A line that runs perpendicular to one side of a triangle and crosses the other two sides equally splits the two sides.

Step 1: Consider side NY, NZ, YM, MX

By the theorem,

[tex]\frac{YN}{NZ}=\frac{YM}{MX}[/tex]

[tex]\frac{3}{NZ}=\frac{5}{5}[/tex]

[tex]NZ=3[/tex] units

Step 2: Consider sides YM, YX, NM, ZX

[tex]\frac{YM}{YX} =\frac{NM}{ZX}[/tex]

[tex]\frac{5}{10} =\frac{6}{ZX}[/tex]

[tex]ZX = 12[/tex] units.

Therefore, the values for the sides are NZ = 3 units and XZ = 12 units.

Answer:

x=20

Step-by-step explanation:

-12+x=8

Add 12 on both sides (-12 + 12 + x = 8 + 12)

which crosses out -12

identity property of addition

Step-by-step explanation:

The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.

A composition is a operation two functions in which the independent variable of the first function is substituted by the entire second function. In other words, we have the following expressions:

[tex](f\,\circ\,g) (x) = f(g(x))[/tex] (1)

[tex](g\,\circ \,f)(x) = g(f(x))[/tex] (2)

If we know that [tex]f(x) = 2\cdot x - 3[/tex] and [tex]g(x) = 4 - x^{2}[/tex], then we have the following compositions:

[tex](f\,\circ\, g) (x) = 2(4-x^{2})-3[/tex]

[tex](f\,\circ\,g)(x) = 5-2\cdot x^{2}[/tex]

[tex](g \circ f) (x) = 4 - (2\cdot x-3)^{2}[/tex]

[tex](g\,\circ f) (x) = -4\cdot x^{2} +12\cdot x -5[/tex]

The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.

The upper and lower bounds for the numbers are illustrations of approximation

The numbers are given as:

a = 6.54 (to 3 significant figures)

b = 123 (to 3 significant figures)

(a) a + b

We have:

a + b = 6.54 + 123

a + b = 129.54

When approximated, the bounds to three significant digits are:

Lower bound = 129

Upper bound = 130.1

(b) ab

We have:

ab = 6.54 * 123

a + b = 804.42

When approximated, the bounds to three significant digits are:

Lower bound = 804

Upper bound = 805

(c) a/b

We have:

a/b = 6.54/123

a/b = 0.0531707317

When approximated, the bounds to three significant digits are:

Lower bound = 0.0531

Upper bound = 0.0532

(d) b - 1/a

We have:

b - 1/a = 123 - 1/6.54

b - 1/a = 122.847094801

When approximated, the bounds to three significant digits are:

Lower bound = 122

Upper bound = 123

Answer:

when two lines are parallel the two slopes are equal (m1 =m2)

when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)

m1 =1st slope

m2= 2nd slope

using the formula y= mx +c

m1= -8/9

m2= 9/8

since m1 is not equal to m2 and -8/9 × 9/8 = -1

It is perpendicular

Answer:

X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.

Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.

Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.

Step-by-step explanation:

[tex]6x+2\left(2x-3\right)=18[/tex]

Expand 2(2x-3) by applying Distributive law:

[tex]2\times \:2x-2\times \:3[/tex]

Multiply:

[tex]2\times \:2x=4[/tex]

[tex]2\times \:3=6[/tex]

[tex]4x-6[/tex]

[tex]6x+4x-6=18[/tex]

Combine like terms:

[tex]6x+4x=10x[/tex]

[tex]10x-6=18[/tex]

Add 2 to both sides:

[tex]10x-6+6=18+6[/tex]

[tex]10x=24[/tex]

Divide both sides by 10:

[tex]\frac{10x}{10}=\frac{24}{10}[/tex]

[tex]x=\frac{12}{5}[/tex]
