The formula of area for triangles: [tex]\frac{1}{2}bh[/tex]
[tex]\frac{1}{2}[/tex] * 7 = 3.5 (3.5 *2) = 7
The formula for area of a rectangle: bh
7*3 = 21
Add the areas together 21+7 = 28 squared cm
Answer:
28cm²
Formula of area of triangle:
1/2 x base x height
Formula of area of rectangle:
length x width
thus,
area of the whole thing:
(1/2 x 7cm x 2cm)+(3cm x 7cm)
=7cm²+21cm²
=28cm²

find the angle of elevation of a kite on a 50m
string flying 40m vertically above the ground.
The angle of elevation of a kite is 53.13°
What is angle of elevation?"It is the angle formed by the line of sight and the horizontal plane for an object above the horizontal surface."
What is sine angle?"For a right triangle, the sine of acute angle [tex]\theta[/tex] is,
[tex]sin(\theta)=\frac{opposite ~side}{hypotenuse}[/tex]"
For given question,
Consider the following diagram for given question.
The length of the string (AC) = 50m
The kite is flying 40m vertically above the ground.
⇒AB = 40m
We need to find the angle of elevation [tex]\theta[/tex]
Consider the sine of angle [tex]\theta[/tex]
[tex]\Rightarrow sin(\theta)=\frac{AB}{AC} \\\\\Rightarrow sin(\theta)=\frac{40}{50}\\\\\Rightarrow sin(\theta)=0.8\\\\\Rightarrow \theta=sin^{-1}(0.8)\\\\\Rightarrow \theta=53.13^{\circ}[/tex]
Therefore, the angle of elevation of a kite is 53.13°

how can you tell two objects are similar when all you did is make the the object smaller by a scaled factor?
if good answer... will give brainly and also 5 stars and everything
Answer:
You can tell if they are similar if all the angles correspond and the sides are all scaled down by the same factor. For instance, a triangle with sides of 30, 40, and 50 scaled down by a factor of 2 would have sides of 15, 20, and 25.

Elias purchases a home for $38,900. The value of the home, in thousands of dollars, since his purchase is shown in the table. A 2-column table with 6 rows. The first column is labeled years since purchase with entries 0, 5, 10, 15, 20, 25. The second column is labeled value (thousands of dollars) with entries 38.9, 62.4, 89.3, 145.2, 210.8, 326.5. Find an exponential function that models the data. Round numerical values to the nearest hundredth. Let x be the number of years since the purchase. The function f(x) = ( )x models the data. Use the model to predict the home’s value. After 12 years, the home’s value will be about $ thousand. After 35 years, the home’s value will be about $ thousand.
Answer:
f(x)=39.59 (1.09)
Use the model to predict the home’s value.
After 12 years, the home’s value will be about $
111 thousand.
After 35 years, the home’s value will be about $
808 thousand.
Step-by-step explanation:
Edge 2021 :)
A function assigns the values. After 35 years, the home’s value will be about $215.079.68 thousand.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A general exponential equation is given as,
y = A(1+b)ˣ
Now, if x is the number of years since the purchase. And we substitute the value of the x and y from the table. Then we can write,
38.9 = A(1+b)ˣ
A = 38.9
Therefore, the equation can now be written as,
y = 38.9(1+b)ˣ
Substitute the second point in the equation,
y = 38.9(1+b)ˣ
62.4 = 38.9(1+b)⁵
1.604113 = (1+b)⁵
1+b = 1.09912
b= 0.09
Hence, the function that can model the value of the house after x years is y=38.9(1.09)ˣ.
B.) Now the value of the house after 12 years,
y=38.9(1.09)ˣ
y=38.9(1.09)¹²
y = 109.41
The home’s value will be about $ 109.41 thousand.
C.) After 35 years, the home’s value will be,
y=38.9(1.09)ˣ
y=38.9(1.09)¹⁰⁰
y = 215.079.68
After 35 years, the home’s value will be about $215.079.68 thousand.

Datos:
Subió 8 pisos
Piso final= 7
Explicación:
Para resolver el enunciado, se debe tener en cuenta que:
Piso final - Piso inicial= 8
Reemplazando y despejando:
7-Piso inicial= 8
Piso inicial= 7-8
Piso inicial= -1
Por lo tanto, ha salido de la planta del sótano
Verificando:
Piso inicial +8= piso final
-1+8= Piso final
