Find The Lenght Of Side BC. Give Your Answer To 3 Significant Figures

Answers

Answer 1

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

A water hose discharges water at a rate of 45 gallons per minute. Which graph has a slope
that best represents this rate?

Answers

Answer:

F

Step-by-step explanation:

F is the correct graph because the bottom is for minutes and if you drag your finger on the 1 minute you meet 45 which is how many gallon per minute. and if you go to 2 minutes you meet with 90 which is 45+45=90 and 45 is one minute and 90 is 2 minutes.

srry if that was complicated

Hope this helps you!

The graph which best represents the rate of discharge given is graph F.

It is given that discharge rate of a water hose is 45 gallons per minute.

We have to check which graph has a slope that best represents this rate.

What do you mean by discharge rate of water ?

Discharge rate of water is defined as the rate at which drainage water is released from a site.

As per the question ;

The rate of discharge = 45 gallons per minute

So,

We can say that ;

When x = 1 minute

y = 45 gallons

We can conclude that F is the correct graph because the x-axis is for minutes and if you check at time 1 minute you get 45 gallons at the y-axis which shows the no. of gallons per minute.

Thus , the graph which best represents the rate of discharge given is graph F.

Which is the point-slope equation of a line with a slope of 1/2 that contains (4,7)

My answer choices are
A= Y - 7 = 1/2 (x+4)
B= Y - 7 = 1/2 (x-4)
C = Y - 7 = - 4 + (1/2)
D = y + 7 = 1/2 (x+

Answers

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (4, 7) , thus

y - 7 = [tex]\frac{1}{2}[/tex](x - 4) → B

Step-by-step explanation:

Initially, there's only 1 letter.

Tania sends the letter to 4 friends.

Each friend sends a letter to 4 more friends (4 × 4 = 16).

Each of those friends sends to 4 more friends (16 × 4 = 64).

The pattern is 1, 4, 16, 64, etc.

This is a geometric sequence.  The first term is 1 and each term is 4 times the previous term.

Suzanne bought 6 paint sets. Each set contains the same number of brushes. She has 18 brushes. Write and solve an equation to determine the number of paint brushes that came in each paint set. Explain the strategy that you used to solve the equation.

Answers

Answer:

3

Step-by-step explanation:

Given that:

The number of paint sets, Suzanne bought= 6

As each set contains the same number of brushes.

Let x be the number of brushes each set contains.

So, the total number of brushes in 6 sets = 6x.

It is given that the total number of brushes she has is 18, which is equals to 6x.

So, the required equation is

[tex]6x=18[/tex]

[tex]\Rightarrow x=\frac {18}{6}[/tex]

[tex]\Rightarrow x=3.[/tex]

Hence, the number of paint brushes each set contains is 3.

An end behavior model for f(x) =​

Answers

Answer: Choice C) 2x^4

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

As x gets larger and larger, all we really care about is the leading terms. This is because 8x^6 is much larger than -16x^3 and 8 for very very large x values. The larger the exponent, the larger the result will be.

So effectively, the leading term 8x^6 dictates the end behavior for the numerator.

In a similar way, the leading term 4x^2 dictates the end behavior for the denominator polynomial.

Divide the two leading terms:

(8x^6)/(4x^2) = (8/4)*x^(6-2) = 2x^4

The rule used here is (a^b)/(a^c) = a^(b-c)

So as x goes to infinity or negative infinity, it's slowly approaching the asymptote y = 2x^4.

Where are points A' and B' located after dilation, and how are lines f and f' related? A) The locations of A' and B' are A' (0, 2) and B' (6, 0); lines f and f' intersect at point A. B) The locations of A' and B' are A' (0, 6) and B' (2, 0); lines f and f' intersect at point B. C) The locations of A' and B' are A' (0, 2) and B' (2, 0); lines f and f' are the same line. D) The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel.

Answers

Answer:

D (0,6) (6,0)

Step-by-step explanation:

when you multiply it you do the x coordinates first then the y.

so (0,2)  x 3 = (0,6)

(2,0) x 3 = (6,0)

These coordinates are parralel to each other.

The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel, the correct option is D.

What is Transformation?

Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.

Dilation is a process in which the object or the graph is enlarged or compressed by a scale factor.

The coordinates of A( 0, 2)

The coordinates of B(2,0)

The scale factor is 3

The center of dilation of f is at the origin to create line f'.

The points A and B lie on the line f, when line f is dilated, the coordinates will also get dilated.

The coordinate of A after dilation is 3 * (0,2)

A' = (0,6)

The coordinate of B after dilation is 3 * (2,0 )

B' = (6,0)

The line f' will be parallel to the line f.

Wally's grandmother started a college savings account for him with
$3,000. What is the total amount of money in the account after 5 years if
the annual simple interest rate is 3%?
I need this plz help explain the proses thx ASAP

Answers

Answer:

$450

Step-by-step explanation:

You want to calculate the interest on $3000 at 3% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $3000.00.

r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 3000 × 0.03 × 5 to get that:

The interest is: $450.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 3000.00 + 450.00 = 3450.00.

Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.

Answers

Answer:

f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A

Step-by-step explanation:

The vertical line test is used to show that the graph represents a

function or not

If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a function

The horizontal line test is used to show that the function has an

inverse or not

If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverse

Let us look at the given graph

→ The graph represents a parabola, which represents the function f(x)

∵ Any horizontal line drawn will cross the graph in more than one point

∴ f(x) has no inverse

f(x) does not have an inverse function, because its graph fails the

  horizontal line test.
