daser333 [38]

Answer:

The correct answer is B. 3 to 2.

Step-by-step explanation:

To solve this problem let suppose

English = E

History = H

Maths = M

E = H* 2 (there are twice as many English majors as history majors)

E = M* 3 (three times as many English majors as mathematics majors)

lets suppose E=6 then,

H = 3 and M =2

H to M = 3/2.

The inverse function theorem says

$\dfrac{\mathrm df^{-1}}{\mathrm dx}(16)=\dfrac1{\frac{\mathrm df}{\mathrm dx}(f^{-1}(16))}$

We have

$f(x)=x^2+4x-5$

defined on $x>-2$ , for which we get

$f^{-1}(x)=-2+\sqrt{x+9}$

and

$f^{-1}(16)=-2+\sqrt{16+9}=3$

The derivative of $f(x)$ is

$f'(x)=2x+4$

So we end up with

$\dfrac{\mathrm df^{-1}}{\mathrm dx}(16)=\dfrac1{\frac{\mathrm df}{\mathrm dx}(3)}=\dfrac1{10}$

(x²+x+1)+(-2x² 3x+5)

ExtremeBDS [4]

Step one: (((x2)+x)+1)+((0-(2x23•x))+5)

Step two: Check for a perfect cube. 2.1 -2x24+x2+x+6 is not a perfect cube.

2.2 Factoring: -2x24+x2+x+6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: x+6

Group 2: -2x24+x2

Pull out from each group separately :

Group 1: (x+6) • (1)

Group 2: (2x22-1) • (-x2)

The groups have no common factor and can not be added up to form a multiplication.

So the answer would be, -2 (x24) + (x2) ++ 6.

The coordinates of the vertices of quadrilateral ABCD are A(0, −4) , B(−4, 3) , C(3, 4) , and D(6, −1) . Drag and drop the choic

Art [367]

Answer:

The slope of AB is -7/4, the slope of BC is 1/7 , the slope of CD is 5/3, and the slope of AD is 2. So, Quadrilateral ABCD is neither a parallelogram nor a trapezoid because neither pair of opposite sides are parallel.

Step-by-step explanation:

Since, a quadrilateral having,

One pair of parallel opposite sides is Trapezoid,

While, having two pair of parallel opposite sides is parallelogram.

Since, the slope of a line segment having the end points $(x_1, y_1)$ and $(x_2, y_2)$ is,

$m=\frac{y_2-y_1}{x_2-x_1}$

Here, the vertices of the quadrilateral ABCD are A(0, −4) , B(−4, 3) , C(3, 4) , and D(6, −1),

Slope of AB = $\frac{3+4}{-4-0}=-\frac{7}{4}$

Slope of BC = $\frac{4-3}{3+4}=\frac{1}{7}$

Slope of CD = $\frac{-1-4}{6-3}=-\frac{5}{3}$

Slope of AD = $\frac{-1+4}{6-0}=\frac{3}{6}=2$

Hence, Quadrilateral ABCD is neither a parallelogram nor a trapezoid because neither pair of opposite sides are parallel.

Select the two figures that are sThe tree in your friend's yard casts a shadow that is 27 feet long. Your friend is 5 feet tall

Sphinxa [80]

Answer: 30 ft tall

Step-by-step explanation: X= the height of the tree in feet

27/x = 4.5/5

(4.5)(x) = (27)(5)

(4.5)(x) = 135

divide by 4.5 to isolate x

135/4.5 = 30

x = 30

the tree is 30 ft tall
