Answer:

  • 315 kilometers.

Step-by-step explanation:

<u>We know that:</u>

  • 30 kilometers = 1 hour

<u>Solution:</u>

  • 30 kilometers = 1 hour
  • => 30 x 21/2 kilometers = 21/2 hours
  • => 15 x 21 kilometers = 21/2 hours
  • => 315 kilometers = 21/2 hours

Hence, in 21/2 hours, the cyclist rides 315 kilometers.

  • Speed=30km/h
  • Time=21/2=10.5h

\\ \tt\hookrightarrow Speed=Distance/Time

\\ \tt\hookrightarrow Distance=Speed\times Time

\\ \tt\hookrightarrow Distance=30(10.5)

\\ \tt\hookrightarrow Distance=315km

Jessica is baking a cake. The recipe says that she has to mix 96 grams of sugar into the flour. Jessica knows that 1 cup of this
Rudik [331]
1 cup = 128 grams
X cups = 96 grams

Cross multiply
128X = 1*96
X=96/128 cups = 6/8 = 3/4 cups.

If she has already added 1/2 cups, then she needs to add (3/4-1/2)=1/4 cup more sugar.

Also please remind her to do the calculations before adding ingredients to avoid ruining a recipe.

Find the area of the region between the curve y= 2ln(x) and the horizontal axis for 1&lt;= x &lt;= 4
marissa [1.9K]

Answer:

5.09 units

Step-by-step explanation:

Given equation

y=2\ln x=f(x) in the interval 1\le x\le 4

So we integrate y in the given interaval

\int f(x)=2\int\limits^4_1 {\ln x}dx

Let us integrate \ln x first.

let

u=\ln x, dv=dx

du=\dfrac{1}{x}, v=x

\int\ln x dx=udv

Using integration by parts we get

uv-\int vdu

=x\ln x-\int x\dfrac{1}{x}dx

=x\ln x-dx

=x\ln x-x+C

So here

\int f(x)=2\int\limits^4_1 {\ln x}dx\\ =2(x\ln x-x)_1^4\\ =2[(4\ln 4-4)-(1\ln 1-1)]\\ =2[4\ln 4-4+1]\\ =5.09\ units

The area of the the region between the curve and horizontal axis is 5.09 units.
