On the grid shown, each grid line represents one mile. What is the shortest distance, to the nearest tenth of a mile, between Hillburn and Dunford?

Answer:

R325

Step-by-step explanation:

Cost to buy shoes (x)

x = 175 * 50

x = 8750

At this point they've lost R8750 (-8750)

7500 = -8750 + 16250

To make an overall profit of R7500 they would need to sell the shoes at

16250 / 50 = R325

Answer:

sin(90-25) = sin(65)

Step-by-step explanation:

cos(a) = sin(90-a)

The statement that is true about her rate of change in elevation is  She descended at a rate of 920 feet per hour.

From the question, Jacinta traveled from an altitude of 4,450 feet above sea level to an altitude of 150 feet below sea level, then the total distance traveled will be

D = 4450 + 150

D = 4600 feet

If Jacinta drove at a constant speed and the trip took her five hours, her rate will be expressed as:

Rate = Total distance/Time

Rate = 4600/5

Rate = 920 feet perhour

Hence the statement that is true about her rate of change in elevation is  She descended at a rate of 920 feet per hour.

The distributive property is basically expanding brackets.

So if you take 3(x + 4) = 36 and remove the brackets (so multiplying out the 3), you get:

3x + 12 = 36

And from there you simplify :)

3x + 12 = 36

3x = 24

x = 8

The distributive property was used to multiply the 3 through the brackets, thus making the equation easier to solve I guess

Answer:

No, you did not get a B+, you got an 85.6% for the class

Step-by-step explanation:

So, let's split the grades into different parts:

Quiz: 15%

Exam1: 15%

Exam2: 15%

Exam3: 15%

Homework: 10%

Final: 30%

Each part of the grade adds up together to be 100%, so here, we are going to multiply each weighting of the grade with the average amount of points you got for each assignment then add it all up.

(Notice how I convert the percentages to decimals to make it easier to multiply)

Quiz: 0.15(85) = 12.75

Exam1: 0.15(78) = 11.70

Exam2: 0.15(81) = 12.15

Exam3: 0.15(92) = 13.80

Homework: 0.10(85) = 8.50

Final: 0.3(89) = 26.70

Adding these all up:

12.75 + 11.70 + 12.15 + 13.80 + 8.50 + 26.70 = 85.6

You got an 85.6% for the class, which is not a B+

The value of the logarithm function log₅25 is 2. Then the correct option is C.

Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.

The logarithmic form of 25 will be

We know that if the base of the logarithm is the same as the number then the value of the logarithm will be 1 one that is given as

Then take the log with the base value of 5.

log₅25 = log₅5²

log₅25 = 2 × log₅5

log₅25 = 2

The value of the logarithm function log₅25 is 2. Then the correct option is C.

Answer:

Second answer

Step-by-step explanation:

We are given [tex]\displaystyle \large{\sec \theta = -3}[/tex] and [tex]\displaystyle \large{\sin \theta > 0}[/tex]. What we have to find are [tex]\displaystyle \large{\cot \theta}[/tex] and [tex]\displaystyle \large{\cos \theta}[/tex].

First, convert [tex]\displaystyle \large{\sec \theta}[/tex] to [tex]\displaystyle \large{\frac{1}{\cos \theta}}[/tex] via trigonometric identity. That gives us a new equation in form of [tex]\displaystyle \large{\cos \theta}[/tex]:

[tex]\displaystyle \large{\frac{1}{\cos \theta} = -3}[/tex]

Multiply [tex]\displaystyle \large{\cos \theta}[/tex] both sides to get rid of the denominator.

[tex]\displaystyle \large{\frac{1}{\cos \theta} \cdot \cos \theta = -3 \cos \theta}\\\displaystyle \large{1=-3 \cos \theta}[/tex]

Then divide both sides by -3 to get [tex]\displaystyle \large{\cos \theta}[/tex].

Hence, [tex]\displaystyle \large{\boxed{\cos \theta = - \frac{1}{3}}}[/tex]

__________________________________________________________

Next, to find [tex]\displaystyle \large{\cot \theta}[/tex], convert it to [tex]\displaystyle \large{\frac{1}{\tan \theta}}[/tex] via trigonometric identity. Then we have to convert [tex]\displaystyle \large{\tan \theta}[/tex] to [tex]\displaystyle \large{\frac{\sin \theta}{\cos \theta}}[/tex] via another trigonometric identity. That gives us:

[tex]\displaystyle \large{\frac{1}{\frac{\sin \theta}{\cos \theta}}}\\\displaystyle \large{\frac{\cos \theta}{\sin \theta}[/tex]

It seems that we do not know what [tex]\displaystyle \large{\sin \theta}[/tex] is but we can find it by using the identity [tex]\displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta}}[/tex]  for [tex]\displaystyle \large{\sin \theta > 0}[/tex].

From [tex]\displaystyle \large{\cos \theta = -\frac{1}{3}}[/tex] then [tex]\displaystyle \large{\cos ^2 \theta = \frac{1}{9}}[/tex].

Therefore:

[tex]\displaystyle \large{\sin \theta=\sqrt{1-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{9}{9}-\frac{1}{9}}}\\\displaystyle \large{\sin \theta = \sqrt{\frac{8}{9}}}[/tex]

Then use the surd property to evaluate the square root.

Hence, [tex]\displaystyle \large{\boxed{\sin \theta=\frac{2\sqrt{2}}{3}}}[/tex]

Now that we know what [tex]\displaystyle \large{\sin \theta}[/tex] is. We can evaluate [tex]\displaystyle \large{\frac{\cos \theta}{\sin \theta}}[/tex] which is another form or identity of [tex]\displaystyle \large{\cot \theta}[/tex].

From the boxed values of [tex]\displaystyle \large{\cos \theta}[/tex] and [tex]\displaystyle \large{\sin \theta}[/tex]:-

[tex]\displaystyle \large{\cot \theta = \frac{\cos \theta}{\sin \theta}}\\\displaystyle \large{\cot \theta = \frac{-\frac{1}{3}}{\frac{2\sqrt{2}}{3}}}\\\displaystyle \large{\cot \theta=-\frac{1}{3} \cdot \frac{3}{2\sqrt{2}}}\\\displaystyle \large{\cot \theta=-\frac{1}{2\sqrt{2}}[/tex]

Then rationalize the value by multiplying both numerator and denominator with the denominator.

[tex]\displaystyle \large{\cot \theta = -\frac{1 \cdot 2\sqrt{2}}{2\sqrt{2} \cdot 2\sqrt{2}}}\\\displaystyle \large{\cot \theta = -\frac{2\sqrt{2}}{8}}\\\displaystyle \large{\cot \theta = -\frac{\sqrt{2}}{4}}[/tex]

Hence, [tex]\displaystyle \large{\boxed{\cot \theta = -\frac{\sqrt{2}}{4}}}[/tex]

Therefore, the second choice is the answer.

__________________________________________________________

Summary

[tex]\displaystyle \large{\sec \theta = \frac{1}{\cos \theta}}\\ \displaystyle \large{\cot \theta = \frac{1}{\tan \theta} = \frac{\cos \theta}{\sin \theta}}\\ \displaystyle \large{\sin \theta = \sqrt{1-\cos ^2 \theta} \ \ \ (\sin \theta > 0)}\\ \displaystyle \large{\tan \theta = \frac{\sin \theta}{\cos \theta}}[/tex]

[tex]\displaystyle \large{\sqrt{\frac{x}{y}} = \frac{\sqrt{x}}{\sqrt{y}}}[/tex]

There are 12 face cards in a deck of cards

There are 52 cards in a deck

So there are 12 face cards out of 52 cards.

The ratio of this is:

12 : 52

This looks like this in fraction form:

[tex]ratio1 : ratio2[/tex] =   [tex]\frac{ratio1}{ratio2}[/tex]

So the ratio 12 : 52 = [tex]\frac{12}{52}[/tex]

So the answer is 12/52(this can be simplified to 3/13)

The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2 , the value of b is -9.

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.

Given

The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2 .

The axis of the symmetry is given by;

[tex]\rm x=\dfrac{-b}{2a}[/tex]

The value of x is 3/2 and a is 3.

Substitute all the values in the formula

[tex]\rm x=\dfrac{-b}{2a}\\\\\dfrac{3}{2}=\dfrac{-b}{2 \times 3}\\\\\dfrac{3}{2}=\dfrac{-b}{6}\\\\ -b = \dfrac{6 \times 3}{2}\\\\ b = \dfrac{=18}{2}\\\\b =-9[/tex]

Hence, the value of b is -9.
