Find the area of the triangle

Answer:

crazy i need help on the same problem

Step-by-step explanation:

help ?!

Given:

The function is

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,

[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]

At x=-2,

[tex]f(-2)=\left(\dfrac{1}{3}\right)^{-2}[/tex]

[tex]a=\left(3\right)^{2}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]a=9[/tex]

At x=-1,

[tex]f(-1)=\left(\dfrac{1}{3}\right)^{-1}[/tex]

[tex]b=\left(3\right)^{1}[/tex]         [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]

[tex]b=3[/tex]

At x=0,

[tex]f(0)=\left(\dfrac{1}{3}\right)^{0}[/tex]

[tex]c=1[/tex]         [tex]\left[\because a^0=1, a\neq 0\right][/tex]

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.

Step-by-step explanation:

Answer:

$10.50

Step-by-step explanation:

Multiply $3 by 4 since it's 4 pounds nd each pound cost $3. When u do that, u get $12, but u gotta subtract $1.50 off the final cost, which is $10.50.

Ion get the second part.

Answer:

$31.20

Step-by-step explanation:

1. Calculate the tax amount. To do this, you multiply the price by the tax rate.

$780 x 4% = $31.20

The total tax paid was $31.20

Answer:

B

Step-by-step explanation:

janice got ripped off buying a computer for $780.

she could have easily built her own computer with similar specs for less money or use the same amount of money to build a way better pc.

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

The same is to be considered

Answer:

C

Step-by-step explanation:

h=10 so plug that into the given equation

c=3(10) +50

c=30+50

c=80

Answer: C, c = $80

Step-by-step explanation:

c = 3h + 50

c = 3 (10) + 50

c = 30 + 50

c = 80

The total cost is $80

Hope that helped!

Answer:

The reason why these triangles are similar is;

A. AA

Step-by-step explanation:

A two column proof can be presented using the drawing of the question diagram created with Microsoft Visio as follows;

Statement      [tex]{}[/tex]                  Reason

[tex]\overline {AB}[/tex] ║ [tex]\overline {DE}[/tex]   [tex]{}[/tex]                      Given

∠ACB ≅ ∠DCE       [tex]{}[/tex]         Vertically opposite angles

∠BAC ≅ ∠DEC       [tex]{}[/tex]         Alternate interior angles theorem

∠ABC ≅ ∠CED       [tex]{}[/tex]         Alternate interior angles theorem

ΔABC ~ ΔCDE        [tex]{}[/tex]         By Angle-Angle (AA) similarity postulate

Therefore, the correct option is AA.

Answer:

The cost of each cotton candy bag is $4.

Step-by-step explanation:

Consider the provided information.

Let, the vendor has [tex]x[/tex] dollar at the starting of each day.

Let, the cost of each cotton candy bag is [tex]y[/tex].

Now when she sells a total of 12 bags, she has $128.

[tex]x+12y=128[/tex]  .....(1)

After she sells a total of 20 bags, she has $160.

[tex]x+20y=160[/tex]  ....(2)

Subtract equation 1 from equation 2.

[tex](x+20y)-(x+12y)=160-128[/tex]

[tex]8y=32[/tex]

[tex]y=4[/tex]

Hence, the cost of each cotton candy bag is $4.

Answer:

30.2x+12.9y

The surface area of the square pyramid is 144m²

Step-by-step explanation:

the surface area pyramid is equal to SA = B + Ph/2

Answer:

The Pythagorean Theorem is a squared + b squared = c squared. It is used to find out a side of a triangle if you already know the two others. C is always the H=hypotenuse, while the other two sides are a and b.

Answer: a^2+b^2 (factored) = c^2

Step-by-step explanation:

This only helps if you are solving for the hypotenuse.

Answer:

305$

Step-by-step explanation:

305 because if it costs 61 dollars for 2 tickets and 61/2 30.5. 30.5*10=305

Answer:

$30,750

Step-by-step explanation:.

Paso uno:

datos dados

costo del auto = $ 37,500

% degradación = 18%

= 18/100 * 37,500

= 0,18 * 37,500

= $ 6750

Segundo paso:

deje que el costo total sea T

Por lo tanto

T = coste del coche-% de degradación

T = 37.500-6750

T = 30,750
