There she was first the assistant and then the colleague of Hitchings, with whom she worked for the next four decades. Elion and Hitchings developed an array (variety) of new drugs that were effective against leukemia, autoimmune disorders, urinary-tract infections, gout, malaria, and viral herpes.


Elion believed that new drugs could be developed to help people.


Elion had to work for Hitchings because she was a woman.


Elion worked hard for more than 40 years to earn money for retirement.


Elion and her colleagues were responsible for developing important drugs.

Answer:

[tex]5.6 *10^7[/tex]

Step-by-step explanation:

Given

[tex](4.54*10^8)-(3.98*10^8)[/tex]

Required

Solve

[tex](4.54*10^8)-(3.98*10^8)[/tex]

Apply distributive law of algebra

[tex](4.54 - 3.98) *10^8[/tex]

Evaluate the expression in bracket

[tex](0.56) *10^8[/tex]

Remove bracket

[tex]0.56 *10^8[/tex]

When a number is in standard form: [tex]a * 10^n[/tex]

The value of a must be: [tex]1 \le a \le 10[/tex]

So, the expression becomes:

[tex]5.6 *10^{-1}*10^8[/tex]

Apply law of indices

[tex]5.6 *10^{-1+8}[/tex]

[tex]5.6 *10^7[/tex]

Answer:

b

Step-by-step explanation:

The value of the function (f +g) (x) will be (f +g) (x) = 4x³ – 2x² + 6x + 1. Then the correct option is B.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The functions are given below.

f(x) = 3x² + 6x – 5

g(x) = 4x³ – 5x² + 6

Then the value of the function (f +g) (x) will be

(f +g) (x) = f(x) + g(x)

(f +g) (x) = 3x² + 6x – 5 + 4x³ – 5x² + 6

(f +g) (x) = 4x³ – 2x² + 6x + 1

The value of the function (f +g) (x) will be (f +g) (x) = 4x³ – 2x² + 6x + 1. Then the correct option is B.

Step-by-step explanation:

Is it 25

Answer:

15 ft

Step-by-step explanation:

Let the height of the wall be represented bad x

Applying the theorem of similarity, we would have the following equation:

[tex] \frac{x}{6} = \frac{9 + 6}{6} [/tex]

[tex] \frac{x}{6} = \frac{15}{6} [/tex]

[tex] \frac{x}{6} = \frac{5}{2} [/tex]

Cross multiply

[tex] x*2 = 5*6 [/tex]

2x = 30

Divide both sides by 2

x = 15

Thus, the height of the wall = 15 ft

Answer:

83 in.^2

Step-by-step explanation:

The entire polygon consists of a rectangle with length 8 in. and width 5 in., a triangle with base 8 in. and height 7 in., and another triangle with base 5 in. and height 6 in.

The total are is the sum of the area of the rectangle and the two triangles.

area = area of rectangle + area of first triangle + area of second triangle

area = LW + bh/2 (for the first triangle) + bh/2 (for the second triangle)

area = 8 in. * 5 in. + 8 in. * 7 in. / 2 + 5 in. * 6 in. / 2

area = 40 in.^2 + 28 in.^2 + 15 in.^2

area = 83 in.^2

Given:

The inequality is [tex]y<-2x-4[/tex].

To find:

The graph of the given inequality.

Solution:

The inequality is

[tex]y<-2x-4[/tex]

The related equation is

[tex]y=-2x-4[/tex]

For x=0,

[tex]y=-2(0)-4[/tex]

[tex]y=0-4[/tex]

[tex]y=-4[/tex]

For y=0,

[tex]0=-2x-4[/tex]

[tex]4=-2x[/tex]

[tex]\dfrac{4}{-2}=x[/tex]

[tex]-2=x[/tex]

So, the related line passes through two points (0,-4) and (-2,0).

Sign of inequality is <, so the related line is a dotted line and shaded region is below the related line.

Therefore, the correct option is B.

Answer:

4[tex]\sqrt{5}[/tex]

Step-by-step explanation:

The segment from a vertex to the side opposite is a perpendicular bisector.

The equilateral Δ is divided into 2 right triangles with legs 8 and 4

let height be h, then using Pythagoras' identity

h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )

h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value

Answer:

3/5x + 3/8

Step-by-step explanation:

2/5x + 5/8 + 1/5x - 1/4

1. Combine like terms so now u have

3/5x + 3/8

In case you want to know how I got 3/8

You want a common denominator so

from  5/8 + 1/4, make both denominator 8

so 1 *2/ 4* 2

so now you converted the 1/4 to 2/8

So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8

Hope this helped!

3/5 as a division is 0.6

Step-by-step explanation:

To write a fraction as a division, we basically divide the values, since the fraction represents a division.

In this question:

We want 3 divided by 5.

3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.

So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.
