The area of the triangle is 42 cm².

To calculate the area of a triangle, we need to use the formula:

Area = (base x height) ÷ 2

Therefore, the area of a triangle with a base of 7 cm and a height of 12 cm is:

Area = (7 cm x 12 cm) ÷ 2

Area = 42 cm²

The area of a triangle with a base of 7 cm and a height of 12 cm is 42 cm². This can be calculated by using the formula: Area = (base x height) ÷ 2. The base and the height of the triangle are multiplied together and then divided by two to get the area. Therefore, the area of the triangle is 42 cm².

Step-by-step explanation:

For the passenger to be correct, the two ratios should equal each other.

[tex]\frac{156}{34}[/tex] = [tex]\frac{39}{9}[/tex]  Multiply both sides by 34 and 9

[tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{156}{34}[/tex] = [tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{39}{9}[/tex]  On the left side of the equation, the 34's cancel each other out.  On the right side of the equation, the 9's cancel out.  That leaves us with:

(9)(156) = (340)(39)

1404 = 13260

These numbers do not equal each other so the ratios are not equal.

The line TU is parallel to QR and SQR is dilated version of STU by a scale factor of 4.

What is midpoint theorem?

The line segment of a triangle connecting the midpoint of two sides of the triangle is said to be parallel to its third side and is also half the length of the third side, according to the midpoint theorem.

Through the diagram it can be seen that T and U are midpoints of SQ and SR respectively.

And it can also be seen that TU is parallel to QR.

It is given that ST = 2, TQ = 6, SU = 3 and UR = 9

The length of side SQ -

SQ = ST + TQ

SQ = 2+6

SQ = 8

The length of side SR -

SR = SU + UR

SR = 3+9

SR = 12

The measurement of QR = SQ as seen in the diagram.

According to midpoint theorem the mid points line segment TU measures half of its parallel third side of triangle QR.

The coefficients of the polynomial in this problem are given as follows:

a = 1, b = 4, c = 7, d = 16, e = 12.

Inserting these coefficients into a 4th degree equation solver, the roots are given as follows:

Hence the polynomial is factored as follows:

(x + 2.7 - 2i)(x + 2.7 + 2i)(x + 1)(x + 3).

Applying the subtraction of perfect squares for the first two linear factors, considering that i² = -1, we have that:

(x + 2.7 - 2i)(x + 2.7 + 2i) = (x + 2.7)² - (2i)²

(x + 2.7 - 2i)(x + 2.7 + 2i) = (x² + 5.4x + 11.29).

Hence the factored polynomial is of:

(x² + 5.4x + 11.29)(x + 1)(x + 3).

This is usually expressed as:

The substitution property states that if two expressions are equal, then they remain equal when the same values are substituted into them. This means that if one expression is equal to another, then the same value can be swapped in for any of the variables within them and the equality will still hold.

For example, if we have the equation 4x + 7 = 11, then we can swap in any value for x and the equation will still be true. This is because the substitution property allows us to make a substitution for any of the variables and the equation will remain true.

We randomly selected a sample of 43 movies for the same year.

Excel  α = 0.05,  r^2 = 0.5123

=51.23%

51.23% of the DVD sales variation is explained by annual revenue.

SY.X = 12.2279.

Therefore, the average deviation of predicted DVD sales from the actual is 12.2279 million dollars.

b. The hypothesis being tested is:

Null Hypothesis, H0: β1 = 0

Alternative Hypothesis, H1: β1 ≠ 0

The test statistic, F = (6439.6133/1)/((12570.025 - 6439.6133)/(42 - 1)) = 43.07

The F-critical value is 4.0785.

Since 43.07 > 4.0785, we can reject the null hypothesis.

Therefore, we can conclude that there is a linear relationship between the revenues of DVD sales and the box-office gross.

The average rate of change of f(x) over -6≤x-4 is -70.

The average rate of change of g(x) over -6≤x-4 is -140.

The average rate of change of g(x) is 2 times that of f(x)

The average rate of change of an equation can be determine by using the formula below:

average rate of change = (f(x₂)- f(x₁)) / [x₂- x₁]

From the given information, f(x) = 7x², g(x) = 7x² and  x₁ = -6, x₂ = -4

For f(x) = 7x²:

average rate of change =  ([7(-4)²] - [7(-6)²]) / (-4-(-6))

                                       = (112-252)/2

                                      = -70

For g(x) = 14x²:

average rate of change =  ([14(-4)²] - [14(-6)²]) / (-4-(-6))

Dante deposited $5,000 into an account with an annual interest rate of

3.5%. He plans to deposit an additional $200 each year, just after the

interest is compounded. His balance will be $9,838.44 after 16 years.

It displays the actual percentage rate of interest owed on any outstanding debts, including credit card debt and loans.

Because it takes compounding effects into account, the effective annual interest rate is the real interest rate on an investment or loan. The rate increases as the compounding periods get more frequent. Advertisements for loans or savings accounts may include both the nominal interest rate and the effective yearly interest rate. The rate that should be used to compare loan and investment rates of return is the effective annual interest rate.

We can substitute the known values into the formula and calculate the final balance:

A = $5,000 (1 + 0.035)¹⁶

We can calculate the final balance by using a calculator, or we can use the formula of compound interest:

A = P(1 + r/n)ˣ

where, A= Amount

P= Principle($5,000 )

x= Time(16 years)

n= Rate(3.5%)

A = $5,000 (1 + 0.035/1)¹⁶

Now we can add the $200 deposit each year for 16 years:

A = $5,000 (1 + 0.035)¹⁶ + $200 × 16

A = $9,838.44

In the given question, we have to check that it is possible to construct a triangle whose sides are 2 cm 3 cm and 7 cm.

To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always grater than the third side.

To check this we firstly add the 2 and 3

2 + 3 < 7

5 > 7

Now we add 2 and 7

2 + 7 > 3

9 > 3

Now we add 3 and 7

7 + 3 > 2

Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle.
