Answer:

  T = (4, 9)

Step-by-step explanation:

The midpoint is computed from ...

  Z = (S + T)/2

Solving for T, we find ...

  T = 2Z -S

Using the given coordinates, this is ...

  T = 2(4, 6) -(4, 3) = (2·4-4, 2·6 -3) = (4, 9)

The location of T is (4, 9).

D. 6.30q + 14.40 = 4.50(q + 4)

Step-by-step explanation:

Which equation below represents the situation

A. 3.60(q – 4) + 25.20 = 4.50q

B. 3.60q + 25.20 = 4.50(q + 4)

C. 6.30(q – 4) + 14.40 = 4.50q

D. 6.30q + 14.40 = 4.50(q + 4)

Cost of Cranberry juice = $6.30 per quart

Cost of apple juice = $3.60 per quart.

Let

Cost of q quarts of Cranberry juice = $ 6.30q

Cost of 4 quarts of apple juice = $3.60×4= $ 14.40

Total quarts of cranberry-apple juice mixture = q+4

Terrence wants to make a cranberry-apple juice mixture that costs $4.50 per quart

Total revenue = price × quantity

= $4.50(q+4) (1)

Total cost of the mixture = Cost of q quarts of cranberry juice + cost of 4 quarts of apple juice.

= 6.30q + 14.40 (2)

Equate both equations

$4.50(q+4) = 6.30q + 14.40

It can also be written as

6.30q + 14.40 = 4.50(q + 4)

The correct answer is

D. 6.30q + 14.40 = 4.50(q + 4)

Answer:

The plumber will charge $275

Step-by-step explanation:

Models

Models are used to explain and predict the behavior of real objects or systems and are used in a variety of scientific disciplines.

The situation described in the question asks us to build a mathematical model for the charges for the service of a plumber.

The base fee is often called the fixed fee, which charged even if there is no service time. The plumber charges a base fee of $55.

The variable fee is that who changes for each hour worked. The plumber charges $55 per hour, so the charge for t hours of service is 55t.

The total charges of the plumber are modeled as:

C(t)=55t+55

If the plumber works t=4 hours, the cost will be:

C(4)=55*4+55=$275

The plumber will charge $275

Step-by-step explanation:

a1=ar⁰=12 A2=ar¹=-6

a=12 ar=-6

12r=-6

r=-6/12

r=-1/2

a10=ar⁹

=12*(-1/2)⁹

=12*(-512)

=-3/128

S∞ = a1 / (1-r )

=12/(1-1/2)

=12*1/2

=6

The tenth term of the progression will be -3/128, and the sum to infinity will be 6.

The geometric progression defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

We have been given that the first term of a geometric progression is 12 and the second term is -6

So common ratio r = second term/first term = -6/12= -1/2

The tenth term of the progression will be

⇒ ar¹⁰⁻¹ = ar⁹

⇒ 12(-1/2)⁹

⇒ -12(1/512)

⇒ -3/128

The sum to infinity = a / (1-r )

The sum to infinity = 12/(1 - 1/2)

The sum to infinity = 12 × 1/2

The sum to infinity = 6

Thus, the tenth term of the progression will be -3/128, and the sum to infinity will be 6.

7A - 42

Maximum area = 2ab

from ellipse eqn

x^2 + 4y^2 = 49

(x+4y)^2= 49

underoot both sides

x + 4y = 7 ---eqn1

from

[tex] \frac{ {x}^{2} }{ {a}^{2} } + \frac{ {y}^{2} }{{b}^{2} } = 1[/tex]

(ab)^2 = (ax + by)^2

ab= ax + by

compare to eqn1

ab=7

then, area of the largest triangle will be 14 units.

Answer:

[tex]\boxed {\tt m=\frac{2}{3}}[/tex]

Step-by-step explanation:

Parallel slopes have the same slopes.

If a slope is 2/3, the parallel slope will be the same. So, the parallel slope will also be 2/3.

Therefore, the answer is m=2/3

What is the parallel slope of 2/3 .

We know that parallel slopes have the same slopes.

The parallel slope of 2/3 is 2/3 .

Answer:

4.21×10^10

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)

The 42, 100, 000, 000 in scientific notation wll be 4.21×10^10

The number is written in the form  [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10.

The value in terms of power of 10 is known, helps in easy comparison of quantities differing by a large value.

Given the term as 42, 100, 000, 000

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places, that move will be the exponent on the 10. If the decimal is being moved to the right, the exponent would be negative. If the decimal is being moved to the left, the exponent will be positive.

The term in scientific notation is; 4.21×10^10

Answer:

triangle=8, diamond=3, star=11

Step-by-step explanation:

First you want to start with the equation that only has only shape/variable.

triangle ÷ 2 = 4

multiply both sides by 2 to find that triangle=8.

Now we can plug triangle in another equation.

2+diamond+diamond=triangle

2+diamond+diamond=8

subtract 2 from both sides

diamond+diamond=6

because we know diamond and diamond will be the same, we can divide 6 by 2 to find diamond=3.

Now we can go to the top equation

triangle + diamond + star = 22

8 + 3 + star = 22

11 + star = 22

star = 11
