Answer:

Step-by-step explanation:

 40% + 35 % = 80 %    so 20% are dated after 1980

20% is .20 in decimal form

.20 (1600) = 320 coins dated after 1980

Answer:

.55(220-a) + .90(220-a)

Answer:

I assume that you meant 1.861.

If that is true, then 1.9 would be your answer.

Hope that this helps!

Answer:

1860

Step-by-step explanation:

Answer:

The error made is that the graph of [tex]y=x^{2} +3[/tex] is a vertical translation up by 3, instead of down.

Step-by-step explanation:

Exponential functions, when they are graphed, use the function [tex]f(x)=a(x-h)^{2} +k[/tex].

In the equation, k expresses how much the graph shifts vertically. In this case, the function shifts vertically up by 3 from the parent function, [tex]y=x^{2}[/tex]. So, the translation is actually 3 units up compared to the graph of [tex]y=x^{2}[/tex].

Hope this helps and have an amazing day!! ❤

I don't know if you meant to say hundredth but in this case you said hundred and I can't just make assumptions.

The answer is

- - - - -

0

Like literally, I am not stealing your points but you said to the nearest hundred. So in this case, it'd be 0.

The answer is B brainliest?

Step-by-step explanation:

Hi there! Solving the absolute value equation is like solving a quadratic equation.

[tex] \large{ |x| = a \longrightarrow x = \pm a}[/tex]

[tex] \large{ |x| = \begin{cases} x \: \: \: (x \geqslant 0) \\ - x \: \: \: (x < 0) \end{cases}}[/tex]

From the absolute equation:

[tex] \large{ |4q + 12| = 4}[/tex]

Cancel the absolute symbol and write plus-minus of 4.

[tex] \large{4q + 12 = \pm 4}[/tex]

Solve the equation for q-term.

[tex] \large{4q = \begin{cases} 4 - 12 \\ - 4 - 12 \end{cases}} \\ \large{4q = \begin{cases} - 8 \\ - 16 \end{cases}} \\ \large{q = \begin{cases} - \frac{8}{4} \\ - \frac{16}{4} \end{cases}} \\ \large{q = \begin{cases} - 2 \\ - 4 \end{cases}}[/tex]

Hence, the value of q are -2,-4

Answer:

26.14

Step-by-step explanation:

For the triangles: 3*4=12

For the circle: 28.27/2=14.135

12+14.135=26.135

~26.14

Answer:

Step-by-step explanation:

Estimate the fraction part of the number.

We can estimate the fraction part as 1/2 since its greater than 1/4.

The number becomes 3 1/2.

Best choice is C

Answer:

11/40>10/40=1/4 is a part of ½

so

best estimate is 3 ½.

Answer:

  (a)  an = -4·2^(n-1)

Step-by-step explanation:

The form for the general term is ...

  an = a1·r^(n-1) . . . . . a1 is the first term; r is the common ratio

For a1=-4 and r=-8/-4 = 2, the rule will be ...

  an = -4·2^(n-1)

Answer:

range: {15, 11, 7, -3, -7}

Step-by-step explanation:

when x = -4, y = 15

when x = 2, y = 11

when x = 0, y = 7

when x = 5, y = -3

when x = 7, y = -7

Answer:

C

Step-by-step explanation:

Here's the easy way. There are 3 equations. One of the equations uses y=1. So it must be C.

Answer:

Quadrant 2

Step-by-step explanation:

(-3,3) when plotted on a graph fits into quadrant 2!

So, its more like this:

Using the polar form, a complex number with modulus r and argument θ may be written

z = r(cos 0 + j sin θ)

It follows immediately from Euler’s relations that we can also write this complex number in

exponential form as :

z = [tex]re^{j0}[/tex]

When using this form you should ensure that all angles are measured in radians and not degrees.

The exponential form of a complex number is in widespread use in engineering and science. Since z = r(cosθ + isinθ) and since eiθ = cosθ + isinθ we therefore obtain another way in which to denote a complex number: z = reiθ, called the exponential form.

I'm leaning towards the answer choices A. and C.

But I'm sure it's A because of the two, C has an x. That's the only difference they have.

Here's another example,

Let z=x+iy, its exponential form comes from identifying it as the point (x,y) in the (Argand) plane. This basically amounts to writing it in what would be polar form in the real plane. Writing it as:

z =reiθ

. If you graph the point (x,y) and treat it as a vector its easy to see that r=|z| and θ=tan−1(yx).

For purely real numbers, they are already in exponential form since they are equal to their modulus and θ=0.

Also, you can write:

Re(z)=z+z¯2

if you want to write it purely in terms of z. Both of your numbers are purely real and thus they are already in exponential form. I suppose if you wanted to be strict about it you could write it as:

|1−z|=|1−z|e0i

Answer:

The best answer is of Keira's.

Step-by-step explanation:

The full question is as follows :

Given - Each friend predicted how he or she thought the marble would move when it rolled off the end of the track onto the floor.

This is what they said:

Magda : '' I think it will roll in circles.''

Soledad : '' I think it will curve for a bit and then straighten out.''

Allen : '' I think it will roll out in one big curve.''

Keira : '' I think it will roll in a straight line,''

Rafael : '' I think it will zigzag for a little while.''

To find - Which friend do you most agree with ?

Proof -

The best answer is Keira's.

The marble having the track will travel in a straight line.

The behavior is true for all objects.

If no outside force act on an object, the object will travel in a straight line at a constant speed.

When the marble leaves the end of the track, it is no longer in contact with the walls of the track.

That is , the marble has no longer a center-pushing force.

According to Newton's First law, an object remains at rest or in uniform motion in a straight line unless acted upon by an external force.

Since, there is no longer a center-pushing force so the marble rolls off the end of the track in a straight line path across the floor.

Answer:

The sum of any 360-gon's interior angles is 64440 degrees.

Step-by-step explanation:

Answer:

64,440 is the sum of all the interior angles, 179 is the measure of one interior angle

Step-by-step explanation:

We will use the equation x = (n-2) 180 x is the sum of all the interior angles and n is the number of sides this figure has, so we solve

x = (360-2) 180

x= (358) 180

x= 64,440

So the sum of all the interior angles is 64,440

to find each interior angle we must divide the sum of all the interior angles by the number of sides the figure has, so we would divide 64,440 by 360

64,440/360 = 179

Therefore, the measure of each interior angle is 179

give the question and I will try if I couldn't srry

Answer:

4x + 8x = 180

12x = 180

x = 15
