Answer:

sin(45°)= AC/9

cos(45°)= BC/9

Step-by-step explanation:

This is a right angle triangle:

∠ABC =∠CAB = 45°

Now

AC= CB

AB = 9 units.

We will apply sines:

sine(45°)= AC/AB

We know that AB = 9 units.

So substitute the value of side AB

sin(45°)= AC/9

Now apply cos(45°)

cos(45°)=  BC/AB

Again substitute the value of AB:

cos(45°)= BC/9

Thus the answer is

sin(45°)= AC/9

cos(45°)= BC/9  ....

Answer:

2) y-x=2

Add x on both sides:

 y        =x+2

The slope is 1 and the y-intercept is 2.

Step-by-step explanation:

So a linear equation in slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

Let's put all of these in that form:

1) y+x=2

Subtract x on both sides:

 y     =-x+2

The slope is -1 and the y-intercept is 2.

2) y-x=2

Add x on both sides:

 y        =x+2

The slope is 1 and the y-intercept is 2.

3) y-x+2=0

Add x on both sides:

 y     +2=x

Subtract 2 on both sides:

 y        =x-2

The slope is 1 and the y-intercept is -2.

4) y+x-2=0

Add 2 on both sides:

 y +x      =2

Subtract x on both sides:

 y           =-x+2

The slope is -1 and and the y-intercept is 2.

Option C (f(x) = x^2)

Step-by-step explanation:

Quadratic Function is a polynomial which has a maximum degree of 2. It is expressed in the form:

f(x) = a + bx + cx^2; where a, b, and c are real numbers.

Any function which has the highest degree of 2 (not more than that) is the quadratic function. Option A illustrates the absolute values function. Option B shows a function which does not match the characteristics of the quadratic equation. Option D shows a linear function. Therefore, Option C (i.e. f(x) = x^2) is the correct choice!!!

Step-by-step explanation:

Let's go through each step and see.

First step: They distribute and they did so correctly. -4(x+8)=-4x-32.

Second step: They added 2x on both sides.  

Third step:  They added 32 on both sides.

Fourth step: The divide both sides by -2 correctly but since this is inequality you must flip the sign.

For example 3>2 but if you multiply both sides by -1 or divide both sides by -1 you get -3<-2.

You have to flip the sign whenever you multiply or divide both sides of inequality by negative number.

Final answer:

The expression 1(y), when y = -5/8, is calculated by multiplying 1 by -5/8, which simply yields -5/8.

Explanation:

The task is to find the value of the expression 1(y) when y is given as -5/8. The expression 1(y) can be interpreted as simply '1 times y'. Therefore, we need to multiply the number 1 by -5/8 to find the answer.

1(y) = 1 * (-5/8) = -5/8

This is a basic arithmetic operation, specifically multiplication, commonly encountered in mathematics. When we multiply any number by 1, the result is the number itself, which in this case applies to the negative fraction -5/8.

The measure of <2 is 45 degree.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is always 180 degrees.

From the figure, applying angle sum property

<2 + 45 + 90= 180

<2 + 135=180

<2 = 180- 135

<2 = 45 degree

Thus, the measure of <2 is 45 degree.

Step-by-step explanation:

Point T is reflected over the y-axis.

Therefore, the coordinates are (-2, 5).

Answer:

T' is (-2,5)

Step-by-step explanation:

To reflect a point across the y-axis, you will note the following:

1- the sign x-coordinate of the point is flipped while the value remains the same

2- both the sign and the value of the y-coordinate remain the same

We are given that:

point T is (2,5)

Applying the above:

sign of x-coordinate is flipped and value is the same :

x- coordinate of T' is -2

both sign and value of y-coordinate are the same:

y-coordinate of T' is 5

Based on the above:

T' would be (-2,5)

[tex]3 \le x \le 7[/tex].

Step-by-step explanation:

Hopefully this will help. Let me know in the comments if it doesn't.

The domain is all the x's where the function exists. The function you have starts at x=3 and ends at x=7. There are no breaks in your line between those numbers for x. So your domain is all x's between 3 and 7 ( inclusive).

So that means all values of x that is greater than or equal to 3 and values of x less than or equal to 7.

Soh Cah Toa

In some trigonometry classes, this acronym is very important to solving questions like this.

Why?

It tells us the right triangle-definition of these trigonometry functions.

We have that cosine of an angle is equal to tge side that is adjacent to it over the hypotenuse.

So here we are asked to find cos(B).

Lets look at triangle respect to the angle B

The measurement of the side that is opposite is 64.

The measurement of the side that is adjacent is 48.

The measurement of the hypotenuse is 80.

So cos(B)=48/80.

Let's reduce. 48 and 80 have a common factor of 8 so divide numerator and dexter by 8. This gives us:

cos(B)=6/10.

One more step in reducing. Both factors are even so cos(B)=3/5.

[tex]\frac{x-2}{x^2-x-2}[/tex]

Step-by-step explanation:

A removable discontinuity is when there is a hole in your graph. This is usually because one X value has been canceled out. Most of the time, it takes factoring to figure out if there is a removable discontinuity when looking at an equation.

First, look at the numerator [tex]x-2[/tex] . This can't be factored any further. However, [tex]x^2-x-2[/tex] can be factored since it is a trinomial (has three terms) .

For the purposes of this example, you may want to think about it as

[tex]1x^2 -1x-2[/tex]

To factor, multiply the the outside coefficients

1 x -2 = -2

Now take the middle coefficient (-1) and ask yourself what two numbers multiply to make -2, but still add to be -1.

-2 x 1 = -2

-2 + 1 = -1

So in factored form, the equation is

[tex]\frac{x-2}{(x-2)(x+1)}[/tex]

Since you have x-2 on both top and bottom, that can be canceled out. x - 2 would be your removable discontinuity in this situation.

A removable discontinuity can occur in a function if there are common factors in both the numerator and denominator that can be canceled out.

A function has a removable discontinuity at a particular point if the function is undefined at that point but can be made continuous by redefining the value at that point. To identify the removable discontinuity, we need to factor both the numerator and denominator of the function. By factoring, we can determine if any common factors exist that can be canceled out, resulting in a removable discontinuity.

Oil added or consumed during the day equals evening oil level minus morning oil level (g - h).

To calculate how much oil was consumed or added during the day, you can use the formula:

Change in oil = g - h

If the value is positive, it means oil was added.

If the value is negative, it means oil was consumed (leaked or used).

For example, if in the morning your car had 5 liters of oil (h = 5) and in the evening it had 7 liters (g = 7):

Change in oil = 7 - 5 = 2 liters

This means 2 liters of oil were added during the day.

Answer:

40

Step-by-step explanation:

Subtracting a number k from 300 looks like this 300-k.

Adding a number k to 220 looks like this 220+k.

They are saying for some number k that we have 300-k and 220+k is the same value.

That is, 300-k=220+k.

This is the equation we are going to solve for your number.

300-k=220+k

Add k on both sides:

300=220+2k

Subtract 220 on both sides;

80=2k

Divide both sides by 2:

40=k

k=40.

So the number is 40.

Check: 300-40=260 while 220+40=260.

To simplify the expression 43 + 2(3 - 2), first solve inside the parentheses (3 - 2 = 1), then multiply by 2 (2 × 1 = 2), and finally add to 43 to get 45.

Explanation:

The question asks to simplify the expression 43 + 2(3 − 2). To simplify, follow the order of operations, often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). First, solve the expression within the parentheses, which is 3 − 2 = 1. Next, multiply the result by 2 (2 × 1 = 2). Lastly, add this result to 43 to get the final answer, 43 + 2 = 45. This process demonstrates how to approach and simplify mathematical expressions using proper order of operations.

Step-by-step explanation:

Let her normal rowing speed be x

Also note the formula D = RT, where d is distance, R is rate(speed) and T is time

On windy day, her speed is x + 4

On against wind return, her speed is x - 4

With wind, she can go 48 miles in same amount of time when she goes 24 miles against wind. This can be written as:

48 = (x+4)T

24 = (x-4)T

We can write each equation in terms of T and equate both. So we have:

48/x+4 = T

24/x-4 = T

Thus,

[tex]\frac{48}{x+4}=\frac{24}{x-4}\\48(x-4)=24(x+4)\\48x-192=24x+96\\24x=288\\x=\frac{288}{24}\\x=12[/tex]

Step-by-step explanation:

So the first vector G is 40.3 m long in a -35 degree direction.

Lat's find the components of G.

[tex]G_x=40.3\cos(-35)=33.0118[/tex].

[tex]G_y=40.3\sin(-35)=-23.1151[/tex].

The second vector H is 63.3 m long in a 270 degree direction.

[tex]H_x=63.3\cos(270)=0[/tex].

[tex]H_y=63.3\sin(270)=-63.3[/tex].

The resultant vector can be found by adding the corresponding components:

[tex]R_x=G_x+H_x=33.0118+0=33.0118[/tex]

[tex]R_y=G_y+H_y=-23.1151+(-63.3)=-86.4151[/tex]

Now we are asked to find the magnitude of [tex](R_x,R_y)[/tex] which is given by the formula [tex]\sqrt{R_x^2+R_y^2}[/tex].

Since [tex](R_x,R_y)=(33.0118,-86.4151)[/tex] then the magnitude is [tex]\sqrt{(33.0118)^2+(-86.4151)^2}=\sqrt{8557.34844}=92.51[/tex].

The magnitude of the sum of vector G (40.3m, -35°) and vector H (63.3m, 270°) is found by breaking each vector into its components, summing these components, and using the Pythagorean theorem. The magnitude of the sum of these vectors is approximately 92.1 m.

Given that vector G has a magnitude of 40.3 m and is in a -35.0° direction, and vector H has a magnitude of 63.3 m and is in a 270° direction, the sum of these vectors can be determined. This sum is found by breaking each vector into its component forms, adding the components together, and then using the Pythagorean theorem to find the magnitude of the result.

For vector G: Gx = 40.3m * cos(-35) = 33m and Gy = 40.3m * sin(-35) = -23.14m. For vector H: Hx = 0 (as sin(270) equals 0) and Hy = -63.3m (as sin(270) equals -1). The sum vector S = (Gx+Hx, Gy+Hy) = (33m+0 , -23.14m-63.3m) = (33m, -86.44m). Thus, to find the magnitude of the sum of the vectors, we use the Pythagorean theorem: |S| = sqrt((33m)² + (-86.44m)²) = 92.1 m (rounded to 1 decimal place).
