Which expression is equivalent to cos(103°)cos(54°) – sin(103°)sin(54°)?

sin(49°)
cos(49°)
sin(157°)
cos(157°)

Answers

Answer:

D - cos(157)

Step-by-step explanation:

Cos sum angle identity

cos(A+B) = cosAcosB - sinAsinB

103+54=157

The correct answer to the question is Cos 157

There are two ways to solve this question:

Method 1:

Evaluate: Cos103Cos54 – Sine103Sine54

This can be obtained as follow:

Cos103Cos54 – Sine103Sine54

= –0.1322 – 0.7883

= –0.9205

Next, we shall evaluate each option given in the question to see which will be equivalent to –0.9205. This is illustrated below:

Sine 49 = 0.7547

Cos 49 = 0.6561

Sine 157 = 0.3907

Cos 157 = –0.9205

From the above evaluation, we can see that Cos 157 is equivalent to Cos103Cos54 – Sine103Sine54

Thus, Cos 157 is the correct answer to the question.

Method 2

Again, we can apply the addition formula from trigonometry.

Cos (A – B) = CosACosB + SineASineB

Cos (A + B) = CosACosB – SineASineB

Sine (A + B) = SineACosB + SineBCosA

Sine (A – B) = SineACosB – SineBCosA

Comparing

Cos103Cos54 – Sine103Sine54 with the formula given above, it is very clear that:

Cos103Cos54 – Sine103Sine54 = Cos(103 + 54)

Cos103Cos54 – Sine103Sine54 = Cos 157

Recall:

Cos103Cos54 – Sine103Sine54 = –0.9205

Cos 157 =  –0.9205

Therefore, Cos 157 remains the correct answer to the question.

b. should have substituted 1 instead of -1
c. should have solved the equation a + 18 = -17
d. correctly substituted and evaluated the polynomial)

Answers

Answer:

Step-by-step explanation:

Correct steps to find the value of 'a' should be,

Braulio's synthetic division should be,

-1  |     1       5         a          -3           11

   

               -1        -4        (4 - a)     (a - 1)  

         1      4     (a - 4)     (1 - a)     (a + 10)

Here remainder is (a + 10).

So (a + 10) = 17 ⇒ a = 7

Braulio Incorrectly found a value of 'a' because he should have used (-1) instead of 1.

Zahra's calculation by remainder theorem should be,

p(x) = x⁴ + 5x³ + ax² - 3x + 11

p(-1) = (-1)⁴ + 5(-1)³ + a(-1)² - 3(-1) + 11

      = 1 - 5 + a + 3 + 11

      = (a + 10)

Since, remainder of the solution is 17,

(a + 10) = 17 ⇒ a = 7

Zahra incorrectly found the value of 'a' because she incorrectly solved the powers to (-1).

Answer: incorrectly, should have used -1 instead of 1

incorrectly, incorrectly applied the powers to -1

Step-by-step explanation:

What is the inverse of function f? f(x)=10/9r+11

Answers

[tex]f(x) = \frac{10}{9}x + 11 \\ [/tex]

So :

[tex]y = \frac{10}{9}x + 11 \\ [/tex]

Subtract the sides of the equation minus 11

[tex]y - 11 = \frac{10}{9}x \\ [/tex]

Multiply the sides of the equation by 9

[tex]9(y - 11) = 10x[/tex]

[tex]9y - 99 = 10x[/tex]

Divided the sides of the equation by 10

[tex] \frac{9y - 99}{10} = x \\ [/tex]

So :

Answers

Answer:

The value of x is 7

Step-by-step explanation:

M, N and P are collinear means they lie on the same line.

Mathematically;

MP = MN + NP

Thus;

6x-22 = 3x -9 + x + 1

6x-22 = 4x -8

6x -4x = -8 + 22

2x = 14

x = 14/2

Alyssa’s lemonade recipe calls for 9 lemons for every 2.5 gallons of water. Brian’s recipe calls for 12 lemons for every 4 gallons of water. Whose lemonade will require more water if they each use 36 lemons? . can you help me

Answers

Answer:

Alyssa’s lemonade recipe

Step-by-step explanation:

→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe

9 lemons = 2.5 gallons

(÷ 2.5)      =     (÷ 2.5)

3.6 lemons = 1 gallon

→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe

12 lemons = 4 gallons of water

(÷ 4)            =    (÷ 4)

3 lemons = 1 gallon of water

→ Now compare

Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon

Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water

Brian's lemonade recipe requires more water.

Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.

Three sides of a triangle are consecutive even integers. The
perimeter of the triangle is 48 in. Find the side lengths of the
triangle.

Answers

Answer:

The side lengths of the triangle are 14, 16, and 18.

Step-by-step explanation:

(x) + (x + 2) + (x + 4) = 48

3x + 6 = 48

3x = 42

x = 14

(14) = 14

(14 + 2) = 16

(14 + 4) = 18

The required lengths of side of triangle are 14 in, 16 in and 18 in.

What is a triangle?

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

Given that,

Sides of a triangle are consecutive integers.

Also given that,

Perimeter of triangle is 48.

Let the sides of triangle are x, x+2 and x +4.

x + x + 2 + x + 4 = 48

3x = 48 - 6

3x = 42

x = 14

The length of the triangles  

x + 2 = 14 + 2 = 16

x + 4 = 14 + 4 = 18

The side lengths of the triangle are 14, 16 and 18.

1. A line goes through the points (0,7) and (1,9). Write the following equation forms:
Point-Slope Form (using the point (1,9):
Slope-Intercept Form:
Standard Form:
2. Write the following equation forms given that f(−3)=4 and f(−1)=−4 are true of the line: Slope-Intercept Form:
Standard Form:

Answers

So the options are in y=mx+b aka slope intercept form, so since the slope is 1/2, and passes through (2,-3) the equation will be y=1/2x+2. So the answer is y = one-half x + 2.

Point slope form equation: y-y1=m(x-x1)
Where m=slope
Y1 is any y value from a point on the graph
X1 any x value from the same point on the graph

The first thing to do is find the slope

M= (9-7)/(1-0)=2/1=2

Next is to sun in values

the point given is (1,9)

So we put 9 in place of y1 and 1 in place of x1

So the line in point slope form is

Y-9=2(x-1)

Y intercept formula: y=mx+b

The only new letter is b which is the y intercept value (0,b)

The y intercept is the point where x is 0 which the problem says is (0,7)

So, keeping the same slope

The answer is

Y=2x+7

Standard form: Ax+By=C

Where A,B, and C are integers (can’t be fractions)

If you reorder the slope intercept form

You get

-2x+y=7

You have to flip the signs because a needs to be positive

So the answer is

2x-y=-7

2)

When you see something like f(-3)=4
That is saying when x is equal to -3, the whole equation is equal to 4

So f(x)=n

So when x is -3, y is 4 and when x is -1, y is -4

M=(4+4)/(-3+1)=8/-2=-4

Sub in points to find b

4=-4(-3)+b
4=12+b
b=-8

So,

Y=-4x-8

Std form

Move -4x to the left with addition to get

4x+y=-8
