Answer:

13.5

18.1

72.2

12.8

66.1

31.8

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4.  We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/  0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue

. Use the smaller hand as the hour hand and the bigger hand to track each minute.

Answer:

It's B, Points a and f. -5 and 5

Answer: The slope is -5/3 or -1.4

Algebra

[tex]s = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]s = \frac{5}{3} [/tex]

In the circumference formula given d is the diameter which is 2 times r ( r is the radius)

R is given as 6 feet, diameter = 2 x 6 = 12 feet.

Circumference = 12 feet x 3.14 = 37.68 feet

Answer:

(-10, -8)

Step-by-step explanation:

4u

Each component of vector u is multiplied by 4. So

u = (3, 1)

4u = (4*3, 4*1) = (12,4).

v – 4u

Subtraction of the components of vector v by the components of the vector 4u. So

v - 4u = (2, -4) - (12, 4) = (2-12, -4 - 4) = (-10, -8)

The value is (-10, -8)

Answer:

Simulateneous equation

Step-by-step explanation:

Have to slove the equation given then plot the graph

Answer:

Graph a line segment with endpoints (1,-8) and (-4,3).

Step-by-step explanation:

Just identity the endpoints of the line segment given, then swap the coordinates for each pair to graph it's inverse.

Original point -> Corresponding inverse point

(a,b) ->(b,a)

(-8,1) ->(1,-8)

(3,-4) ->(-4,3)

So graph the other inverse which is also a line segment using endpoints (1,-8) and (-4,3).

(The inverse graph is just a reflection of the original relation over y=x.)

Answer:

Is it any of the rational numbers?  There are an infinite number of rational numbers.  Rational numbers are any numbers that can be written as a fraction.  All the integers between those two points (-2, -1, 0, etc.) are all rational.  Any of the numbers between the points would be too. 1/2, 1/3, 2 1/3, etc.

Answer:

16 and 18

Step-by-step explanation:

(n + 2)² - n² = 68

Expand

(n² + 4n + 4) - n² = 68

4n + 4 = 68

Subtract 4 from both sides

4n = 64

Divide both sides by 4

n = 16

n + 2 = 18

The two consecutive even numbers are 16 and 18.

A number system is defined as a system of writing to express numbers.

The difference of the squares of two consecutive even integers is 68.

We need to find the two numbers.

Let the first even number is x+2

The second number will be x

(x+ 2)² - x² = 68

(x² + 4x + 4) - x² = 68

4x + 4 = 68

Subtract 4 from both sides

4x = 64

Divide both sides by 4

x= 16

x + 2 = 18

Hence, the two consecutive even numbers are 16 and 18.

Answer:

C

Step-by-step explanation:

The radius is 7, but in the standard form for a circle, the radius is squared which means that the answer is NOT A and B.

So now you have only two choices, C and D both of which have the radius shown as 49 which is 7 squared.

The center is at (5,-1)

that means that x will be written as (x - 5)

And y will be written as (y + 1)

Note: the signs of the center always change to the opposite of what they were.

The answer is (x - 5)^2 + (y  + 1)^2 = 49

Answer:

Step-by-step explanation:

===============================================

Explanation:

Refer to the diagram below. Notice how I've formed 3 rectangles underneath the curve. The term "right Riemann sum" refers to the idea of making each rectangle's upper right corner be on the curve. The upper left corner spills over top, meaning we have an over-estimate going on here.

Simply find the area of each rectangle, and then add up those sub areas. That will get you to the final answer.

Note how we go from x = -1 to x = 5, which is a distance of 5-(-1) = 6 units. Split three ways and each interval is 6/3 = 2 units wide.

If we started at x = -1, then increasing 2 units leads us to x = -1+2 = 1 as the first x input we compute into f(x). This is the height of the first rectangle.

Then 1+2 = 3 is the next input, meaning f(3) is the height of the next rectangle, and so on. We keep going until all rectangles are accounted for.

----------------------

You should have these rectangle heights:

when moving from left to right.

They add up to 3+29+127 = 159. Double that to get to the final answer of 2*159 = 318

The formula I'm using is

[tex]\Delta x*(f(x_1) + f(x_2) + \dots f(x_n))[/tex]

where x1,x2,... represents the values 1, 3, and 5. These are the x values plugged into the function to get the corresponding heights (3, 29, 127)

Answer:

3 x 4 x 380

Step-by-step explanation:

The correct strategy that he could use would be

3 x 4 x 380

This is basically splitting up the 12 into two numbers whose product equals 12. This shrinks the numbers and makes it easier to multiply the 380. Since it is easier to multiply 380 by 4 as opposed to 12. This strategy will still give you the same result as 12x380 and both will give you a product of 4,560

[tex]Vertex = (-2,-25)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = (x - 3)(x + 7)[/tex]

Required

The vertex

[tex]f(x) = (x - 3)(x + 7)[/tex]

Open bracket

[tex]f(x) = x^2 -3x+7x-21[/tex]

[tex]f(x) = x^2 +4x-21[/tex]

Express -21 as 4 - 25

[tex]f(x) = x^2 +4x+4-25[/tex]

Group as:

[tex]f(x) = (x^2 +4x+4)-25[/tex]

Factorize the expression in bracket

[tex]f(x) = (x+2)^2-25[/tex]

The vertex form is:

[tex]f(x) = a(x - h)^2 + k[/tex]

Where the vertex is:

[tex]Vertex = (h,k)[/tex]

[tex]Vertex = (-2,-25)[/tex]
