You can do 280/40 would give you the answer for one minute, then whatever you get, multiply be 280, that is your answer for number 14.so it would be for every one minute you ride 7 miles. so it would be 7 miles times 20 minutes because you are calculating for an hour and we already have 40 minutes, it would give you 140 miles for 20 minutes, then you add 140 +280 which would give you your answer which is 420m/hr. if you read it step by step you would be able to understand.

What are the next three terms of the sequence below?

vichka [17]

Answer:

64, 256, 1024 (D)

Step-by-step Explanation:

The sequence is following some rule. And the rule is: Multiplying the term with 4 to get the next term. Like:

$1 × 4 = 4$
$4 \times 4 = 16$

Similarly, the next terms are:

$16 \times 4 = 64$
$64 \times 4 = 256$
$256 \times 4 = 1024$

The terms are 64, 256, 1024 which matches with Option D. And that's the correct answer

En un parallelogramo, los lados opuestos son paralelos. De la misma forma, los angulos opuestos son iguales y los angulos adjacentes suman 180 grados.

Con ello, podemos decir que:

a. Los lados RS y UT son paralelos.

b. Los lados RU y ST son paralelos.

c. El angulo en U es igual al angulo en S pues son opuestos

d. Los angulos en S y T son adjacentes . Esto quiere decir que, su suma es igual a 180 grados.

e. El angulo en R es igual al angulo en T pues son opuestos.

f. De forma similar al caso d, los angulos U y R son adjacentes, su suma es 180 grados.

D/dx(sin x/2+cos x) = (a + b cos x)/(2+cos x)^2 find a and b.

Talja [164]

Answer:

a = 1 and b = 2

Step-by-step explanation:

Using the Quotient Rule>

d/dx[(sin x)/(2+cos x) ]

= [(2 + cos x) * cosx - sin x * - sin x)] / (2 + cos x)^2

= 2cos x + cos^2x + sin ^2 x) / (2 + cos x)^2

But cos^2x + sin^2x = 1 so we have:

(1 + 2 cos x) / (2 + cos x)^2

- so a = 1 and b = 2.

Find the value of X and y

tekilochka [14]

Answer:

x=24cm

y=20,78cm

Step-by-step explanation:

sen(30)= $\frac{12}{x}$ -> x*sen(30)=12 -> x= $\frac{12}{sen(30)}$ = 24cm

cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
