Answer:

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)

Step-by-step explanation:

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:

Step-by-step explanation:

Solving for r

Answer: -7

Step-by-step explanation:

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.

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).

Answer:

123 ft

Step-by-step explanation:

create a right angle triangle from the given info.

your perpedicular will be tree height and hypotneus will be 145 feet

sin 45=Tree height/145

122.96=tree height

123 ft

The height of the tree will be equal to 123 feet.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that a zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°.

Create a right-angle triangle from the given info. your perpendicular will be tree height and your hypotenuse will be 145 feet

sin 45=Tree height/145

122.96=tree height

123 ft

[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 .
