Answer:

Scale factor of 1/3!

Step-by-step explanation:

Scale factoring is pretty easy! Since the scale is smaller, this means your scale factor would be a fraction! You can literally just divide the scale size by the actual size to find your answer, so 36/12! The answer to that is three, to the answer in all is 1/3!

I hope this made sense, lol, but if you need more help, im here!

The average rate of change in a function from a to b is

\frac{f(b)-f(a)}{b-a}.


For the left function, from x = 4 to x = 5, the rate of change is


\frac{100-64}{5-4} = \frac{36}{1} = 36.


For the right function, the rate of change is


\frac{1024-256}{5-4} = \frac{768}{1} = 768


Using a ratio to compare the right function's growth rate with that of the left function, you get 768 \div 36 \approx 21.3.


The right function is growing approximately 21 times faster than the left function (over the interval from 4 to 5).

Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina com 1mx0,8m. Sabendo que ele recortou 2 triângulos, a
Gnom [1K]

Answer:

7190 cm²

Step-by-step explanation:

Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina de 1 m x 0,8m.

Passo 1

Determine a área de todo o papelão

= Temos dimensões = 1mx0,8m

Área = Comprimento × Largura

= 0,8m²

Nós convertemos para cm²

1 m² = 10.000 cm²

0,8m² = x cm²

Multiplicação cruzada

0,8m² × 10.000 cm² / 1 m²

= 8000 cm²

Passo 2

Sabendo que recortou 2 triângulos, ambos com 20cm de base e 30cm de altura

Encontramos a área de um triângulo

= 1/2 × base × altura

= 1/2 × 20 × 30

= 300cm²

Ele cortou 2 triângulos Portanto, o são dos dois triângulos = 300cm² × 2

= 600cm²

etapa 3

Ele também cortou 2 trapézios ambos com bases de 10cm e 20cm e altura de 7cm.

A área de um trapézio =

1/2 (a + b) h

= 1/2 (10cm + 20cm) × 7cm

= 1/2 × 30 × 7

= 105 cm²

Ele cortou dois trapézios, portanto

A área dos dois trapézios do corte = 105cm² × 2

= 210 cm²

Passo 4

A área total do papelão que foi cortado = 600cm² + 210cm²

= 810 cm²

Etapa 5

Determine em cm² quanto de papelão sobrou.

Isso é calculado como:

Área total do papelão - Área total que foi cortada

= 8000 cm² - 810 cm²

= 7190 cm²

yaroslaw [1]
D=s*t
distaance=speed times time

cd=coyote distance*time=ds*dt
rd=rabbit diatance*time=rs*rt

given
t=6 for all, so dt=rt=6

and ds=43
rs=35


cd=43*6=258miles
rd=35*6=210miles

how much more?
258-210=48

GE = 3x - 11 FD = 2.x Find GE<br>Can someone help me??​
11Alexandr11 [23.1K]

Answer:

22

Step-by-step explanation:

Given the following

GE = 3x - 11 FD = 2x

Let us assume GE is parallel to FD, hence GE = FD

3x - 11 = 2x

3x - 2x = 0+11

x = 11

Get GE

GE = 3x - 11

GE = 3(11)-11

GE= 33 - 11

GE = 22

Hence the length of GE is 22
