In the paper airplane, ABCD ≅ EFGH, m∠B = m∠BCD = 90, and m∠BAD = 143. Find m∠FEH.

Frank owns 300 acres of land. If he divides the land into 1/2 acre plots, how many plots will he have?

ohaa [14]

If there are 300 acres, each split in half, than the number of plots will be twice that: 600. Frank has 600 plots of land.

What is the solution of the equation below ?

saveliy_v [14]

Answer:

d = ±7i

Step-by-step explanation:

d^2 -1 = -50

Add 1 to each side

d^2 -1 = -50

d^2 = -49

Take the square root of each side

sqrt(d^2) = sqrt(-49)

d = sqrt(-1) sqrt(49)

d = i( ±7)

d = ±7i

Answer:

Like radicals are radicals that have the same number in the radical sign

So it would be 3√7 and 11√7 (reasoning is they both have a 7 underneath the radical sign)

For the second one Simplify: 35√11-√11

you want to subtract like normal 35√11-1√11, (since there isn't a number there we are going to put one)

35-1=34

34√11, You want to keep the √11, because it is like having like terms but instead of variables it is √

34√11

The third one: Simplify: 15√6+3√6

we want to do the same thing as the problem above so,

15+3=18

18√6, again you want to keep the radical the same

18√6

For the fourth one: 5√7+√7-2√7

you want to do one step at a time so

5√7+√7= 6√7 (again you would have a one in front of the √7, then you would keep your radicals the same)

Then you want to subtract that to your other one

6√7-2√7= 4√7

6-2=4, (again keep the radical the same)

4√7

For the last one

3√5*√10+11√5*√10-√5

You always want to multiply first as in PEMDAS

Lets take this one step at a time also

First 3√5*√10

When multiplying radicals you would multiply like normal

3√50 (√5*√10= √50)

3√50

Now lets do 11√5*√10

again √5*√10=√50

so 11√50

Now you are going to add your two answers together

3√50+11√50= 14√50 (you would add 3+11=14, keep the radicals the same)

Don't forget about your -√5

14√50-√5, this as simplified as you can get so your answer is

14√50-√5

I hope this helps you ;)

Can you help me im not that good at math and its a clear photo<br><br> y =___x^2+__x+______

geniusboy [140]

Vertex/General Form: y = a(x - h)^2 + k, with (h,k) as the vertex
(x + y)^2 = x^2 + 2xy + y^2
Standard Form: y = ax^2 + bx + c

So before I put the equation into standard form, I'm first going to be putting it into vertex form. Since the vertex appears to be (-1,7), plug that into the vertex form formula:

$y=a(x-(-1))^2+7\\y=a(x+1)^2+7$

Next, we need to solve for a. Looking at this graph, another point that is in this line is the y-intercept (0,5). Plug (0,5) into the x and y placeholders and solve for a as such:

$5=a(0+1)^2+7\\5=a(1)^2+7\\5=a+7\\-2=a$

Now we know that <u>our vertex form equation is y = -2(x + 1)^2 + 7.</u>

However, we need to convert this into standard form still, and we can do it as such:

Firstly, solve the exponent: $y = -2(x^2+2x+1) + 7$

Next, foil -2(x^2+2x+1): $y = -2x^2-4x-2+7$

Next, combine like terms and <u>your final answer will be: $y = -2x^2-4x+5$ </u>

1) You will begin by writing down the definition of "monetary policy."

stepan [7]

It should be noted that monetary policy simply means the policy that's adopted by the monetary authority in a country in order to control interest rates and the money supply.

<h3>Monetary policy.</h3>

Your information is unclear but the clear and complete ones will be answered appropriately. The main monetary policies include the reserve requirement, open market operations, discount rate, and the interest on reserves.

It should be noted that a larger money supply leads to the reduction of the market interest rates. This makes it less expensive for consumers to borrow.

Also, a smaller money supply raises the market interest rates. Expansionary monetary policy leads to an increase in the money supply. This will lead to an increase in expenditure and therefore, the aggregate demand will shift to the right.
