A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35

percent. However, when five independent laboratories conducted the same experiment, they measured a reduction rate of only 5–8 percent.
How did these laboratories show that the pharmaceutical company’s claims were invalid?

The labs used the pharmaceutical company’s inadequate data.
The labs produced false data.
The labs recorded data incorrectly.
The labs were unable to reproduce the pharmaceutic

Answer:

  5x^2 +10x

Step-by-step explanation:

The area is the product of the height and width. For this exercise, it is convenient to compute the rectangle areas individually, then write their sum:

  blue rectangle area = (5x)(x) = 5x^2

  red rectangle area = (5x)(2) = 10x

Total area = 5x^2 +10x.

_____

If you start by writing an expression for the total area, expanding it requires you deal with the unlike terms separately anyway:

  5x(x +2) = 5x(x) +5x(2) = 5x^2 +10x

8 divide by 1 1/4 KCF
Diano4ka-milaya [45]

Answer:

32/5

Step-by-step explanation:

K=Keep the first Fraction (You can rewrite 8 as 8/1 for when you multiply across.)

C=Change the Division Sign to a Multiplication Sign

F=Flip the Second Fraction

First, rewrite 1 1/4 as 5/4 (A mixed number can be changed to a fraction by multiplying the outside whole number by the denominator or bottom number of the fraction, then add the new rewritten whole number and the original fractional piece. In this case you would multiply the outside 1 by the bottom 4 and add it to the original 1/4. 4/4+1/4=5/4)

Second, Flip 5/4 to 4/5 and change your equation so it now reads: 8/1 x 4/5

Third, use simple fraction multiplication and multiply across to get 8/1 x 4/5=32/5

In this problem, x = c1 cos t + c2 sin t is a two-parameter family of solutions of the second-order DE x'' + x = 0. Find a solut
Norma-Jean [14]

Differentiate the given solution:

x=C_1\cos(t)+C_2\sin(t) \implies x'=-C_1\sin(t)+C_2\cos(t)

Now, given that <em>x</em> (<em>π</em>/4) = √2/2 … (I'm assuming there are symbols missing somewhere) … you have

\dfrac{\sqrt2}2=C_1\cos\left(\dfrac\pi4\right)+C_2\sin\left(\dfrac\pi4\right)

\implies\dfrac1{\sqrt2} = \dfrac{C_1}{\sqrt2}+\dfrac{C_2}{\sqrt2}

\implies C_1+C_2=1

Similarly, given that <em>x'</em> (<em>p</em>/4) = 0, you have

0=-C_1\sin\left(\dfrac\pi4\right)+C_2\cos\left(\dfrac\pi4\right)

\implies 0=-\dfrac{C_1}{\sqrt2}+\dfrac{C_2}{\sqrt2}

\implies C_1=C_2

From this result, it follows that

C_1+C_2=2C_1=1 \implies C_1=C_2=\dfrac12

So the particular solution to the DE that satisfies the given conditions is

\boxed{x=\dfrac12\cos(t)+\dfrac12\sin(t)}

Solve for x. Round to the nearest tenth, if necessary.
blsea [12.9K]

Answer:

ST = x = 1.8 (to the nearest tenth)

Step-by-step explanation:

STU is a right triangle right angled at T with S =61° and hypotenuse SU=3.7 units.

ST = x = SUcos(61°) = 3.7cos(61°) = 3.7*0.48481 = 1.7938
