Answer:

The prime factorization of 196 is 196 = 2 × 2 × 7 × 7 and can be represented as 196 = 2 2 × 7 2 using exponents.

Answer:

2² × 7² = 196

Step-by-step explanation:

Reason:

Odd degree polynomials do not have an absolute max nor absolute min. The curve stretches forever upward and downward. The range is the set of all real numbers.

Even degree polynomials on the other hand do have a highest point or lowest point, depending on the leading coefficient. If the leading coefficient is negative, then the curve has a highest point. If the leading coefficient is positive, then the curve has a lowest point.

Example: y = x^3 does not have an absolute max, but y = -x^2 does.

The company's profit in the year 2003 is $3.1 million

Profit is defined as the amount of revenue generated after deduction of all the liabilities.

Given that in the year 2000 profit = $2.2 million

Each year increase in profit = 13% =0.13

Total number of year = 2003-2000=3 years

Profit is denoted by

[tex]profit=initial profit(1+each.year.increase)^{years}[/tex]

Substituting the values we get

profit=[tex]2.2(1+0.13)^3[/tex]

The equation of the line that goes through the points (−3,−4) and (9,7) can be written in the form 5x - 12y = -75.

To find the equation:

The available points are (3,5) and (9,10).

The line's slope is given by:

[tex]\mathrm{m}=\frac{(10-5)}{[9-(-3)]}=\frac{5}{12}[/tex]

The equation is as follows:

[tex]\begin{aligned}&y-5=\left(\frac{5}{12}\right)[\mathrm{x}-(-3)] \\&\mathrm{y}-5=\left(\frac{5}{12}\right)(\mathrm{x}+3)\end{aligned}[/tex]

By solving a linear equation we can see that the value of x is 28, and with that, we can see that the measure of the left angle is 85 degrees, and the measure of the right angle is 50 degrees.

We know that the angle at vertex S measures 135°, then we can write the linear equation:

(3x + 1)° + (2x - 6)° = 135°

First, we need to solve this for x.

3x + 1 + 2x - 6 = 135

5x - 5 = 135

5x = 135 + 5 = 140

x = 140/5 = 28

Now that we know the value of x, we can find the two measures, which are:

QSR = (3x +1) = (3*28 + 1)° = 85°

RST = (2x - 6)° = (2*28 - 6)° = 50°

The measure of the left angle is 85 degrees, and the measure of the right angle is 50 degrees.

Step-by-step explanation:

The higher the denominator, the higher number of times  a number will be divided which means, the number will become smaller.

False,  there is not enough information provided to Prove that both the triangles are congruent.

Triangles have three sides and three angles, as we discovered in pre-algebra. We also discovered that a triangle's total angle is 180 degrees.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them.

Two triangles must have the same angles and, as a result, must be congruent if their sides are the same. If two triangles are congruent or not, we may determine this simply by looking at their sides.

These two triangles are also equivalent if we know that two sides of one triangle and the angle between them are congruent to two sides and the angle between them of another triangle.

If we know that two angles and the side between them in one triangle are congruent with two angles and the side between them in another triangle, then these two triangles are probably congruent.

When two angles and a non-included side in one triangle are congruent to the corresponding angles and side of another triangle, we are left with the final scenario that results in congruent triangles.

Step-by-step explanation:

Answer: x= -3

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

First you must start by multiplying the parentheses by -5. Once you do that, your equation comes out to -35x+45-6=144. Then you must combine like terms which comes out to -35x+39=144. After that you must get x by itself, so to do that subtract 39 from 144 which comes out to 105. Then you must do the opposite of multiplication and divide 105 by -35 which comes out to x=-3.

Now the scale of the other drawing of a window is

1 cm to 12 inches.
