If g(x) = 4x² - 16 were shifted 9 units to the right and 1 down,
what would the new equation be?

Answer:

-14 or (6,20)

Answer: 25.6

Step-by-step explanation:

[tex](d-3) \tan 37^{\circ}=17\\\\d-7=\frac{17}{\tan 37^{\circ}}\\\\d=\frac{17}{\tan 37^{\circ}}+3 \approx \boxed{25.6}[/tex]

Using an exponential function, it would take 824 minutes before the amount of medication in Aldi's bloodstream is effectively 0.

A decaying exponential function is given as;

[tex]A(t) = A(0)e^-kt[/tex]

Where A = initial value

k = decay constant

We have the half-life of amoxicillin as 62minutes, to determine k, we get

[tex]A(62) = 0. 5(0)[/tex]

[tex]A(62) = 0.5A(0)[/tex]

[tex]0. 5A(0) = A(0) e^{-62k}[/tex]

Solve the exponential function thus

[tex]e^{-62k} = 0. 5[/tex]

㏑ [tex]e^{-62k}[/tex] = ㏑ 0. 5

- 62k = ㏑ 0.5

Make k subject of formula

k = -㏑[tex]\frac{0. 5}{62}[/tex]

k = 0. 011179

The equation is given by

[tex]A(t) = A(0)e^-0.011179[/tex]

We have

[tex]0. 0001A(0) = A(0)e^-0.01179[/tex]

[tex]e^-0.011179t = 0. 0001[/tex]

㏑ [tex]e^-0.011179[/tex] = ㏑ 0.0001

[tex]-0.011179t = In 0.0001[/tex]

t = [tex]-\frac{In 0. 0001}{0. 011179}[/tex]

t = [tex]824[/tex]

Therefore, it would take 824 minutes before the amount of medication in Aldi's bloodstream is effectively 0.

The number of 1 foot cubic blocks that can be stuffed in the pyramid are; 10,583 cubes

The equation for the surface area of a square pyramid is;

Surface area = A + 1/2·p·s

where;

A = area of base

p = perimeter

s = slant height

The volume of the pyramid = (1/3) × A × h

Where:

A = Area of the base = 20 × 20 = 400 ft²

h = The height of the pyramid = √((slant height)² - ((base side length)/2)²)

h = √(80² - (20/2)²) = 30√7

The volume of the pyramid = 1/3*400*30·√7 = 4000·√7 ft³ = 10,583.005 ft³

If the cubes are flexible, then there are approximately 10,583 cubes

For rigid cubes we have;

Given that the height of the pyramid = 30·√7

The slope of the pyramid = (30/10)√7 = 3·√7

A increase in height of 1 foot gives a reduction in width of 2/(3√7)

The bottom can hold 400 cubes, Then next layer can hold;

19 × 19 = 361

If we continue to iterate, we will get a total of approximately 9915 rigid cubes in the pyramid.

Take the LCM

[tex]\frac{(ax + by)(x - y) -(ax - by)(x + y)}{(x + y)(x - y)}= 2(a - b)[/tex]

Expand

[tex]\frac{ax^2 - axy + bxy - by^2 -ax^2 - axy + bxy + by^2}{(x + y)(x - y)}= 2(a - b)[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are as follows:

We want [tex]\Delta < 0[/tex], hence, for equation -4x² - 4x - 6, we have that a = -4, b = -4, c = -6, hence:

Answer:

Hello! The answer to your question is 12:10.

Step-by-step explanation:

1 hour after 10:55 is equivalent to 11:55. Now, we have 15 minutes remaining. We can add in increments of 5 to get to 15 in terms of time:

11:55 + 5 minutes

= 12:00 + 5 minutes

= 12:05 + 5 minutes

The missing number from the triplet x, 48, 52, using the triplet 5, 12, 13, is found to be 5.

The Pythagoras Theorem states that in a right triangle, the square of the hypotenuse is always equal to the sum of the squares of the other two legs.

If the hypotenuse is taken as a, and the two legs are taken as b and c, then by the Pythagoras Theorem, we can write that:

a² = b² + c².

A Pythagoras triplet, is the combination of c, b, and a.

If all three sides of a right triangle are multiplied by the same quantity, we get another right triangle, where the sides of both make Pythagoras Triplet.

In the question, we are given a unique triplet: 5,12, 13, and are asked to find x in x, 48, 52.

We divide the second triplet by the first one, to get:

x/5, 48/12, 52/13,

or, x/5, 4, 4.

The ratio of the two triplets will always be a constant, thus

x/5 = 4,

or, x = 5*4 = 20.

Thus, the missing number from the triplet x, 48, 52, using the triplet 5, 12, 13, is found to be 5.

The area of the circular field in square meters will be equal to, 1386 m².

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass a compact figure's surface. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given information in the question,

Total number of posts = 66

Distance between two posts = 2 meters

Then, the circumference of the area will be,

= 66 × 2 = 132 meters

Now, let's find the radius of the circle,

C = 2πr

132 = 2 × 3.14 × r

r = 132/(2 × 3.14)

r = 21.01 m

Use the formula for the area of the circle:

The probability that a person wins the game is 32.1%

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more has a relative frequency of 9. Therefore, the probability that a person wins the game will be:
