4. If triangle ABC has the following measurements, find the measure of side c:
a = 5
B = 7
C = 42 degrees

Hint : The product of the slopes of two lines perpendicular to each other is - 1 .

______________________________

In slope-intercept ( y = ax + b ) from of the linear equations the coefficient of x is the slope of the line.

Thus :

Slope of line a = - 14

______________________________

Suppose that the slope of line b is x according to the Hint we have :

- 14 × x = - 1

negatives simplify

14x = 1

Divide both side by 14

14x ÷ 14 = 1 ÷ 14

x = 1/14

So the slope of line b is 1/14

_____________________________

Now let's find the equation of line b by point-slope formula using the point question have us ( 2 , 6 ) :

y - y( given point ) = Slope × ( x - x ( g p ) )

y - 6 = 1/14 × ( x - 2 )

y - 6 = 1/14 x - 2/14

y - 6 = 1/14 x - 1/7

Add both sides 6

y - 6 + 6 = 1/14 x - 1/7 + 6

y = 1/14 x - 1/7 + 42/7

y = 1/14 x + 41/7

And we're done ...

First we need to convert 600 miles per hour into feet per hour,

which is

# 3.168e+6

next, divide both by 60 to get feet per minute, then divide by 60 again on both sides to get feet per second

which is

Answer:

f^-1(x) = -1/5(x+11)

Step-by-step explanation:

f(x) = -5x - 11

y  = -5x - 11

Exchange x and y

x = -5y -11

Solve for y

x+11 = -5y-11+11

x+11 = -5y

Divide by -5

(x+11)/-5 = -5y/-5

-1/5(x+11) = y

f^-1(x) = -1/5(x+11)

Let S be the sample space

S={HH, HT, TH, TT}

n(S)= 4

A: both the coins with some place

B: both the coins with different place

C:at least one tail

D:at the most one head

1) A={TT,HH}

n(A)=2

P(G)= n(A)/n(S)

= 2/4

= 1/2

2) B ={HT, TH}

n(B) = 2

P(B) = n(B)/n(S)

= 2/4

= 1/2

3) C= {HT, TH, TT}

n(C)=3

P(C) = n(C)/n(S)

= 3/4

4). D={HT, TH}

n(D) = 2

P(D) = n(D)/n(S)

= 2/4

Answer: To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

Answer:

1.) Reflect across x-axis

2.) Reflect across y-axis

3.) Move to the right by one unit

Step-by-step explanation:

The reflection rule is ''about the origin''.

Used the concept of reflection that states,

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the origin, the x-coordinate and y-coordinate do not change places and are negated.

Given that,

Two figures VWGY and V'W'G'Y' is shown in the figure.

From the figure,

V = (0, - 2)

W = (- 1, 0)

G = (2, 0)

Y = (5, - 4)

V' = ((0,  2)

W' = ( 1, 0)

G' = (- 2, 0)

Y' = (- 5, 4)

Hence the coordinate satisfies the rule (x, y) → ( - x, - y).

So, the reflection rule is about the origin.

Answer:

2×sqrt(6)×w⁷

Step-by-step explanation:

what I can read here, you need to simplify

sqrt(24×w¹⁴)

= sqrt(24)×sqrt(w¹⁴) = sqrt(4×6)×sqrt(w¹⁴) =

= 2×sqrt(6)×sqrt(w¹⁴)

and taking the square root of something with exponent simply means dividing that exponent by 2

so,

2×sqrt(6)×w⁷

Answer and Step-by-step explanation:

I think you have to factor the expression.

You can take out [tex]a^3[/tex], to get the expression:

[tex]a^3(10a^6-33)[/tex] <- Answer.

When multiplying values with exponents, the exponents add together, and when dividing values with exponents, the exponents subtract from each other.

In this situation, we divided [tex]a^3[/tex] from the expression, with the expressions having exponents of 9 and 3. We subtract 3 from 9 and 3 from 3, resulting in the 6 and 0 (not shown because it isn't needed to show).

Step-by-step explanation:

Answer:

Step-by-step explanation:

To answer this we need only know that negative parabolas are upside down, so by definition, it has a max point at the vertex. To find the vertex (h, k), the easy way to do this is to fill in the following expressions for h and k and solve:

[tex]h=\frac{-b}{2a}[/tex]  and  [tex]k=c-\frac{b^2}{4a}[/tex] (These are derived from the quadratic formula). Filling in knowing our a = -1, b = -7, c = 12:

[tex]h=\frac{-(-7)}{2(-1)}=\frac{7}{-2}=-\frac{7}{2}[/tex]  and

[tex]k=12-\frac{(-7)^2}{4(-1)}=12-(\frac{49}{-4})=12+\frac{49}{4}=\frac{97}{4}[/tex] so the vertex (aka max height occurs at [tex](-\frac{7}{2},\frac{97}{4})[/tex]. Depending upon what is meant by stating the max value, we may only need to state the k value (which is the same as the y coordinate, which is an up or down thing as opposed to the x value which is a side to side thing). The domain is all real numbers, as is the case for all x-squared parabolas, and the range is

R = {y | y ≤ 97/4}

I can't see your choices so match them up from these answers to the ones in the list of choices.

Answer:

Step-by-step explanation:

The trick here is to make sure that the units are standard units, like miles / hour.

10 minutes = 10 / 60 hours.

k = 1/6 of an hour

y = k x

k = y/x

k = 8 miles / 1/6 of an hour

k = 8 * 6 // 1/6 * 6

k = 48 miles / hr

y = k x

y = 48 * x
