What is the answer I will give brainlyest

Answer:

31.5 squared cm

Step-by-step explanation:

Let's start with the triangle part :)

We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.

6cm (base) x 6 cm (height) = 36 cm.

Since it's a triangle, we must divide by 2 which gives us 18 cm.

Now let's move on to the circle.

we have a radius of 3.

in order to find area of a circle, we have to do pi x r squared.

We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.

In the directions, it says use 3 for pi. So we do

3 x 9 which equals 27.

But WAIT- it's a <u>half</u> circle so we <u>divide 27 by 2</u> which gives us <u>13.5 </u><u>cm.</u>

Let's add the two

<u>1</u><u>8</u><u> </u><u>cm </u><u>+</u><u> </u><u>1</u><u>3</u><u>.</u><u>5</u><u> </u><u>cm</u> <u>=</u><u> </u><u> </u><u>3</u><u>1</u><u>.</u><u>5</u><u> </u><u>cm </u><u>squared</u> <u>(</u><u>remember</u><u> </u><u>to </u><u>square </u><u>it </u><u>since </u><u>it's </u><u>area!</u><u>!</u><u>)</u>

<u>I </u><u>hope </u><u>this </u><u>helped!</u><u>!</u><u>!</u><u> </u><u><</u><u>3</u>

Y= -3+ 2x<br><br> 3x+2y=2<br><br> I need help ASAP <br> What the solution for this someone pls
Delvig [45]
Substitute the 1st equation in the 2nd, we get:

3x + 2(-3 + 2x) = 2
3x -6 +4x = 2

7x = 8
x = 8/7

Replace x = 8/7 in equation 1,

y = -3 + 2(8/7) = -3 +16/7 = -5/7

Y’all know this anything about this?
Andre45 [30]

We are given:

  • Parallelogram CDEF
  • ∠C = 13x - 10
  • ∠D = 5x + 10

To Find: ∠E

Concept Used:

  • Adjacent angles of a Parallelogram are Supplementary

Finding the value of 'x':

Since adjacent angles of a parallelogram are Supplementary:

∠D + ∠C = 180

5x + 10 + 13x - 10 = 180              [replacing the values of angle C and D]

18x = 180

x = 10                                          [dividing both sides by 18]

__________________________________________________________

Finding Measure of Angle D:

We are given that:

∠D = 5x + 10

∠D = 5(10) + 10                    [since x = 10]

∠D = 60°

__________________________________________________________

Finding the measure of ∠E:

∠D and ∠E are Adjacent angles

Since Adjacent angles are Supplementary:

∠D + ∠E = 180

60 + ∠E = 180

∠E = 120°                                  [subtracting 60 from both sides]

Hence, the measure of ∠E = 120°

Enter the explicit rule for the geometric sequence.<br><br> 9,6,4,83,…
soldier1979 [14.2K]

Answer:

a_n = 2^(n - 1) 3^(3 - n)


Step-by-step explanation:

9,6,4,8/3,…

a1 = 3^2

a2 = 3 * 2

a3 = 2^2

As we can see, the 3 ^x is decreasing and the 2^ y is increasing

We need to play with the exponent in terms of n

Lets look at the exponent for the base of 2

a1 = 3^2  2^0

a2 = 3^1   2^1

a3 =    3^ 0 2^2

an =   3^      2^(n-1)

I picked n-1  because that is where it starts  0

 n = 1   (1-1) =0

  n=2   (2-1) =1

  n=3  (3-1) =2

Now we need to figure out the exponent for the 3 base

I will pick (3-n)

n =1  (3-1) =2

n =2  (3-2) =1

n=3    (3-3) =0

Answer:

D (0, 2)

General Formulas and Concepts:

<u>Algebra I</u>

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

y = 3/4x + 2

<u>Step 2: Break Function</u>

<em>Identify Parts</em>

Slope <em>m</em> = 3/4

y-intercept <em>b</em> = 2
