You choose 3 vowels out of the 7 tiles shown. How many vowels would expect to get out of 105 tiles?
malfutka [58]

Answer:

45

Step-by-step explanation:

If you treat this as a ratio, it would be 3 vowels to every 7 tiles. If one value in the ratio is multiplied by a number, the other should be multiplied by the same number. So if there are 105 tiles, the 7 in the ratio was multiplied by 15. Multiply the other value, 3, by the same number and you get 45.

∫tan(x)³dx<br>please someone solve this for me ​
castortr0y [4]

Answer:

½ sec²(x) + ln(|cos(x)|) + C

Step-by-step explanation:

∫ tan³(x) dx

∫ tan²(x) tan(x) dx

∫ (sec²(x) − 1) tan(x) dx

∫ (sec²(x) tan(x) − tan(x)) dx

∫ sec²(x) tan(x) dx − ∫ tan(x) dx

For the first integral, if u = sec(x), then du = sec(x) tan(x) dx.

∫ u du = ½ u² + C

Substituting back:

½ sec²(x) + C

For the second integral, tan(x) = sin(x) / cos(x).  If u = cos(x), then du = -sin(x) dx.

∫ -du / u = -ln(u) + C

Substituting back:

-ln(|cos(x)|) + C

Therefore, the total integral is:

½ sec²(x) + ln(|cos(x)|) + C

guapka [62]

Answer:

The ratio of bananas to total fruit is 13:21

Step-by-step explanation:

Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.

Answer: 13:21

If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>
