The row of Pascal's triangle that is used to expand the binomial expression  (2x³ +3y³)⁷ is Row eight: 1 7 21 35 35 21 7 1.

A binomial expression is an expression that contains only two terms.

Pascal's triangle is an algorithm for finding the coefficients of a binomial expansion.

Since we require the expansion of the binomial expression (2x³ +3y³)⁷ using Pascal's triangle, we note that, the power of the binomial expression is always equal to the second and second to the last coefficient of the terms in the Pascal's triangle.

So, we see that the Row eight: 1 7 21 35 35 21 7 1, satisfies this condition.

So, the row of Pascal's triangle that is used to expand the binomial expression  (2x³ +3y³)⁷ is Row eight: 1 7 21 35 35 21 7 1.

What is Distributive property?

By the rule of distributive property, multiplying the sum of two or more addends by a number gives the same result as when each addend is multiplied individually by the number and the products are added together.

Given that;

The expression is,

⇒ [ 7/5 × - 3/12 ] ± [ 7/5 × 5/12 ]

Now,

Since, The expression is,

⇒ [ 7/5 × - 3/12 ] ± [ 7/5 × 5/12 ]

Solve the expression by using distributive property as;

⇒ [ 7/5 × - 3/12 ] ± [ 7/5 × 5/12 ]

⇒ [ 7/5 ] × [ - 3/12 ±  5/12 ]

Answer: B

Step-by-step explanation:

For [tex]f(x)=3x-\frac{1}{2}[/tex], comparing it with slope-intercept form yields that the slope is [tex]3[/tex] and the [tex]y[/tex]-intercept is [tex]-1/2[/tex].

For the graphed function, the slope is [tex]\frac{-4-0}{-2-6}=\frac{1}{2}[/tex] and the [tex]y[/tex]-intercept is about [tex]-3[/tex].

Since the absolute value of the slope of the graphed function is less than that of [tex]f(x)[/tex], option B is correct.

The values obtained after solving the given equation is x  = 6 and y = 10.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the information given in the question,

The given equations are,

-5x + 3y = 0   (i)

7x - 4y = 2    (ii)

Multiply equation (i) by -7 and equation (ii) by 5.

35x - 21y = 0       (iii)

35x - 20y = 10       (iv)  

Now, solve the equation for y, because 35x in positive and 35x in negative cancel out each other.

-y = -10

y = 10

Substitute y = 10 in equation (i)

-5x + 3(10) = 0

The vertex of the parabola y = x² - 16x + 24 will be at (8, -40). Then the correct option is D.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = x² - 16x + 24

Convert the equation into vertex form, then we have

y = x² - 16x + 24

y = x² - 2·8·x + 8² - 8² + 24

y = (x - 8)² - 64 + 24

y = (x - 8)² - 40

g. Interest for the fourth quarter = $8.15550685975

h. The amount of interest earned in a year is about $32.56

What is an interest earned on an amount?

An interest is the amount a borrower pays to a lenders as to make use of the lender's funds.

The amount Fred deposited, P = $6,500

The interest paid by the account, r = 0.5% compounded quarterly

a. The first quarter interest can be found by the formula;

C.I. = P[tex](1+ r/4)^{4 . 1/4}[/tex] - P

Therefore

C.I. = 6500 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6500 = 8.125

b. The first quarter ending balance is therefore;

A = P + C.I.

A = $6,500 + $8.125 = $6,508.125

c. The second quarter's interest can be found from the formula;

C.I. = 6508.125 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6508.125 = 8.13515625

The second quarter's interest is $8.13515625

d. The second quarter ending balance is therefore;

A = $6,508.125 + $8.13515625 = $6,516.26015625

The second quarter ending balance is $6,516.26015625

e. The third quarters interest is therefore;

C.I. = 6516.26015625 x  (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6516.26015625 = 8.1432520325

The third quarter's interest is about $8.1433

f. The third quarter's ending balance is therefore;

A ≈ $6516.26015625 + $8.1432520325 = $6,524.40548145

The third quarter's ending balance is $6,524.40548145

g. The fourth quarter's interest can be found as follows;

C.I. = 6524.40548145 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6524.40548145 = 8.15550685975

The fourth quarter's interest is; $8.15550685975

h. The balance at the end of one year is therefore;

Balance = C.I. fourth quarter + Principal for the fourth quarter

Therefore;

Balance = $6,524.40548145 + $8.15550685975 = $6,532.56098831

i. The interest the account earns in a year is therefore;

$6,532.56098831 - $6,500 = $32.5609883

Answer:

The expression is 2 * 3 - 2 + 4 = 8.

Step-by-step explanation:

In this expression, the variables a, b, and c are given specific values. Substituting these values into the expression, we have 2 * 3 - 2 + 4, which simplifies to 8.To evaluate an expression, we substitute the given values for the variables and carry out the operations according to the order of operations (i.e. parentheses, exponents, multiplication and division, addition and subtraction). In this case, the expression is already fully simplified, so we don't need to do any further calculations.

Answer:

No

Step-by-step explanation:

If you look at the first numbers, 1 and 3, we can see that 1 is being multiplied by 3 to get 3.

But if you look at the second numbers, 2 and 4, then you can see that 2 is not being multiplied by 3 to get 4.

Therefore, it is not proportional.

The value of the angle y will be equal to 47.46. The correct option is A.

Supplementary angles are those that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles because the sum of 130° and 50° equals 180°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that the angle x is equal to 132.54°. The value of the angle y will be calculated as,

x + y = 180

132.54 + y = 180

y = 180 - 132.54

y = 47.46

Therefore, the value of the angle y will be equal to 47.46. The correct option is A.

Step-by-step explanation:

Mrs. Smith will need to reserve buses for 7 classes of Fourth graders, with 20 students in each class, for a total of

7 * 20 = <<7*20=140>>140 students.

Since 30 students fit on a bus, Mrs. Smith will need to reserve

140 / 30 = <<140/30=4.67>>4.67 buses.

Since Mrs. Smith can't reserve a partial bus, she will need to reserve 5 buses for the trip.

Answer: 5 busses, you have to multiple the number of students by the amount of classes (7 x 20) to get a product of 140 students. If only 30 can fit on to each bus you have to divide 140 by 30 and you get 4.6666667 so you need to round up to get an answer of 5 busses
