You’re planning to visit with 7 clients today and you estimate that at most each client will require 3/4 hours of your time. At most, how long does your estimate say it will take you to visit with all of these clients?

Answer:  The correct answer is b=5g/(n^3−t)

Step-by-step explanation:

Solve for b in the following equation

n³b - tb = 5g

First factor out variable b

b(n^3−t)=5g

Divide both sides by n^3-t

b(n^3−t)/n3−t=5g/n^3−t

b=5g/(n^3−t)

The equation of plane is x + 11y + 7z - 30 = 0

An equation is said to be a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for example, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

Let  ( x₁, y₁, z₁ ) ( x₂, y₂, z₂ ) ( x₃, y₃, z₃ ) be the coordinates,

we know that equation of plane is:

[tex]\left[\begin{array}{ccc}x-x1&y-y1&z-z1\\x2-x1&y2-y1&z2-z1\\x3-x1&y3-y1&z3-z1\end{array}\right][/tex] = 0

( -2, 1, 3 )  ( 0, 4, 8 )  ( -1, -1, 0 )

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\0+2&4-1&8-3\\-1+2&-1-1&0-3\end{array}\right][/tex] = 0

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\2&3&5\\1&-2&-3\end{array}\right][/tex] = 0

On solving this determinant,

(x+2) (-9+10) - (y-1) (-6-5) - (z-3) (-4-3) = 0

(x+2) - (y-1) (-11) - (z-3) (-7) = 0

x + 2 + 11y - 11 + 7z - 21 = 0

x + 11y + 7z - 30 = 0

Therefore, this is the required equation.

Answer:

a.  335°

Step-by-step explanation:

Bearing: The angle (in degrees) measured clockwise from north.

a.  The bearing from O to A

Measure the angle from the positive y-axis, clockwise to point A.

Angles on a straight line sum to 180°, so the angle between the negative x-axis and point A is (180° - 115°).

b.  The bearing from O to B

Measure the angle from the positive y-axis, clockwise to point B.

c.  The bearing from O to C

Measure the angle from the positive y-axis, clockwise to point C.

d.  The bearing from A to O

Measure the angle clockwise from north of point A to point O.

The side length RQ of the triangle QRT that is 'x' will be 4 units.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

In triangle ΔRST, the side RT is given by the sine of angle 60°. Then we have

sin 60° = (2√3) / RT

(√3)/(2) = (2√3) / RT

RT = 2 x 2(√3) / (√3)

RT = 4

In triangle ΔQRT, the side QR is given by the tangent of angle 45°. Then we have

The expression which represents the function evaluation (f -g)(x) according to the task content is; (f -g)(x) = 2x³ +5x² -8x -4.

Which expression represents (f-g)(x) according to the functions given?

It follows from the task content that the required function evaluation required is; (f -g)(x).

Given;

f(x) = 2x³ +5x² - 6x - 7

g(x)=2x-3

To find;

(f-g)(x).

Since; (f -g)(x) = f(x) - g(x), the resulting expression for (f -g)(x) is;

(f -g)(x) = 2x³ +5x² -6x -7 -2x +3

Collect like terms;

(f -g)(x) = 2x³ +5x² -6x -2x -7 +3

Equation of line parallel to y = − 2 x − 3 and passing through the point (3,-3) is y = -2x + 3.

When two lines are called parallel?

Two lines are parallel lines if they do not intersect.

The slopes of the lines are the same.

f(x)= mx + b and g(x)= nx + c are parallel if m = n.

According to the given question:

Given equation of line is y = −2x − 3

If the new line is parallel, then it will have the same slope.

y = -2x + b

Now this line passes through the point (x,y) = (3,-3) so put in the x and y values into the equation above, solve for b

-3 = -2(3) + b

b = 3

Therefore the required equation of line is

Step-by-step explanation:

The investments arranged from the least to the greatest amount of interest are:

Investment of $1600 at 5% interest rate for 8 years.

Investment of $1600 at 7% interest rate for 8 years.

Investment of $1600 at 7% interest rate for 12 years.

Simple interest is the formula that is used to determine the interest that is earned when an amount is investment at an interest rate over a number of years.

Interest earned with simple interest increases linearly over the investment period. This means that the interest earned each year of the investment period is a constant amount.

Simple interest = amount invested x interest rate x year

Simple interest = $1600 x 0.07 x 8 = $896

Simple interest = $1600 x 0.05 x 8 = $640

Simple interest = $1600 x 0.07 x 12 = $1344

The exact values of the sine and the cosine of the half angle are √(3 / 10) and √(7 / 10), respectively.

Herein we know the exact value of the cosine of an angle set in the first quadrant. Then, the half angle is also in the first quadrant, whose sine and cosine are, respectively:

cos 0.5Ф > 0, sin 0.5Ф > 0

sin 0.5Ф = √[(1 - cos 0.5Ф) / 2]

cos 0.5Ф = √[(1 + cos 0.5Ф) / 2]

First, replace the values of the cosine of the half angle:

sin 0.5Ф = √[(1 - 2 / 5) / 2]

cos 0.5Ф = √[(1 + 2 / 5) / 2]

Second, simplify the resulting expression:

sin 0.5Ф = √[(1 - 2 / 5) / 2]

sin 0.5Ф = √[(3 / 5) / 2]

sin 0.5Ф = √(3 / 10)

cos 0.5Ф = √[(1 + 2 / 5) / 2]

cos 0.5Ф = √[(7 / 5) / 2]

The time it will take the 2000 dollar invested at 8% is t= 9.006468342 years

Compound interest can be define as the addition of interest on the loan to the principal sum of the deposit.

2 = (1+8%) ^t

where t is the time of the year

2= (1 +8%)^t

2 = (1+8/100)^t

2 =   ( 1 0.8)^t

Take the log of both sides

log 2 = log 1.08^t

log 2 = t log 1.08

Divide both sides by log 1.08

log 2/ log 1.08 = t
