Step-by-step explanation:

Neko's flag ended with a triangle having 62 and 86 degrees as base angles because the stick was 12 degrees out of alignment from the proper position (both angles are 74 degrees each) - Option A

Recall:

Thus:

In the base angles of the triangle formed by the flag with the stick are as follows:

180 - 118 = 62 degrees (linear pair)

180 - (62 + 32) = 86 degrees. (sum of triangles)

Neko ended up having a flag that has 62 and 86 degrees base angles.

For both angles to be equal, we would have the following:

In conclusion, Neko's flag ended with a triangle having 62 and 86 degrees as base angles because the stick was 12 degrees out of alignment from the proper position (both angles are 74 degrees each) - Option A

Step-by-step explanation:

Given that:

Time it takes population to double = 21 minutes

Number of bacteria at 10a.m = 8,014,000

Best estimate of bacteria at 10:42

Difference :

10:42 - 10:00 = 42 minutes

42/ 21 = 2 times

Hence it doubles 2 times within the time range :

At 10:21 minutes :

8,014,000 * 2 = 16,028,000

At 10:42 minutes :

16,028,000 * 2 = 32,056,000

Best estimate is 32 million

Step-by-step explanation:

Step-by-step explanation:

In this form, x = 5.

so we'll substitute 5 in for x...

f(5) = -9(5) -10

f(5) = -45 -10

f(5) = -55

Answer:

The receiver should be located at (0, 5.625)

Step-by-step explanation:

The given parameters are;

The width of the satellite dish = 30 inches

The depth of the dish = 10 inches

The receiver should be located at the focus of the parabola

Where the vertex of a parabola is (0, 0)

The equation of an upward or downward facing parabola is x² = 4·p·y

The focus of the parabola = (0, p)

The directrix is given by y = -p

The axis is the x-axis

Therefore, given that the width = 30 inches and the depth = 30 inches, we have;

The points (-15, 10), (15, 10), and (0, 0) (which is the vertex) on the parabola

Substituting, the coordinates into the equation of the parabola gives;

(-15)² = 4 × p × 10

p = (-15)²/(4 × 10) = 5.625

The coordinate of the focus = (0, 5.625)

Therefore, the receiver should be located at (0, 5.625).

The distance that the receiver should be located from the vertex to receive optimal reception is;

5.625 inches above the vertex

We are given;

Width of the satellite dish = 30 inches

Depth of the satellite dish = 10 inches

Vertex of parabola is at (0, 0)

Thus, we can say that this parabola passes through the point (15, 10).

Now, the conic form of a parabola with its vertex at the origin is given by the formula; y = (1/4c)x²

where c is the distance between the focus and the vertex.

Plugging in the relevant values gives;

10 =  (1/4c)(15)²

4c = 225/10

4c = 22.5

c = 22.5/4

c = 5.625

Thus, the receiver should be located at 5.625 inches above the vertex so for optimal reception.

Step-by-step explanation:

The constant of proportionality is 22.

The proportionality constant is the constant value of the ratio of two proportional quantities. When the ratio or product of two changing quantities generates a constant, they are said to be in a proportionate relationship. The proportionality constant's value is determined by the type of proportion between the two specified quantities: direct variation or inverse variation.

We have the equation is

y = 22 x

As, we know that from direct proportion as

y α x

y= k x

where k is constant of proportion

So, y= 22 x gives k =22

Step-by-step explanation:

Answer:

hundreds = 1, for the equation to be true.

Step-by-step explanation:

Given an equation:

[tex]\frac{4}{hundreds}[/tex] = 4 hundreds = 4

For this equation to be true, hundreds should be represented by a minimum value.

This implies that, hundreds can not be represented by a number which equal zero, less than or greater than 1. Therefore, hundreds = 1.

So that;

[tex]\frac{4}{1}[/tex] = 4 x 1 = 4

⇒ 4 = 4 = 4

Thus, a true expression.

For the given equation to be true, hundreds must be equal to 1.

E.g: [tex]\frac{100}{hundreds}[/tex] = 100 hundreds = 100

For this equation to be true, hundreds = 1.

So that;

[tex]\frac{100}{1}[/tex] = 100 x 1 = 100

⇒ 100 = 100  = 100

Answer:

1.027t = 2

Step-by-step explanation:

Given that :

Saving account earns 2.7% interest yearly

The number it will take for the account to double

Let

Number of years = t

Interest earned yearly = 2.7% = 0.027

Amount = p(1 + rt)

Where P = principal

R = rate ; t = time in years, A = final amount

If p = 1 ;

For account to double,

Final amount = 2 * principal (p)

final amount = 2 * 1 = 2 ; hence, Final amount = 2

2 = 1(1 + 0.027t)

2 = 1 + 0.027t

2 = 1.027t

Answer:

$53.21

Step-by-step explanation:

If 10% comes off of the 100% that we would have paid originally, that means we're just paying 90%. That means we've to calculate:

$59.12 * 90% =

$59.12 * .9 =

$53.208.

Because you don't really pay anything past the hundredths place, we can just round the 8 up to get: $53.21

Answer:

$53.21

Step-by-step explanation:

You have a 10% discount so .10 times your total is the discount:

.10 x 59.12 = 5.912

Now, subtract $5.91 from the the total to get the price after a coupon (rounded to 5.91 because cents don't go into the thousandths place):

$59.12 - $5.91

= $53.21

So, your bill is $53.21 after the coupon is used

Answer:

graph as seen below :)

Step-by-step explanation:

when graphing an algebraic equation, it is important to remember mx+b and what it stands for. m is the variable used to describe the slope and when in the form of a fraction is rise over run/vertical over horizontal/up over side/etc. so for this one, start at the y-intercept (0,-2) and go up 1, over 5, then plot that point. then continue the pattern for you graph and do the same backwards so you go down 1 and to the left 5. x is the variable that normally stays a variable in the equation. and finally, b is the y-intercept, so when the line passes through a point where x = 0 (that part is normally confusing form me cuz its the y-intercept so just think of it as when the point is on the y axis). then, you can plot points to make the graph shown below. sorry the graph is kinda trash but you can see that when you go over 5 you go up one.

if you have any questions make sure to comment so that i can clarify anything thats a little silly or confuzzling :)
