Answer: 55

Step-by-step explanation:

Given

Values are presented in the Venn diagram

No of left-handed students $n(A)=25$

No of vegetarians students $n(B)=45$

Students who are left-handed and vegetarian is given by $n(A\cap B)=15$

$n(A\cup B)$ is given by $n(A\cup B)=n(A)+n(B)-n(A\cap B)$

Put the values

$n(A\cup B)=25+45-15\\n(A\cup B)=55$

A curve is given by y=(x-a)√(x-b) for x≥b, where a and b are constants, cuts the x axis at A where x=b+1. Show that the gradient

ankoles [38]

Answer:

A curve is given by y=(x-a)√(x-b) for x≥b. The gradient of the curve at A is 1.

Solution:

We need to show that the gradient of the curve at A is 1

Here given that ,

$y=(x-a) \sqrt{(x-b)}$ --- equation 1

Also, according to question at point A (b+1,0)

So curve at point A will, put the value of x and y

$0=(b+1-a) \sqrt{(b+1-b)}$

0=b+1-c --- equation 2

According to multiple rule of Differentiation,

$y^{\prime}=u^{\prime} y+y^{\prime} u$

so, we get

${u}^{\prime}=1$

$v^{\prime}=\frac{1}{2} \sqrt{(x-b)}$

$y^{\prime}=1 \times \sqrt{(x-b)}+(x-a) \times \frac{1}{2} \sqrt{(x-b)}$

By putting value of point A and putting value of eq 2 we get

$y^{\prime}=\sqrt{(b+1-b)}+(b+1-a) \times \frac{1}{2} \sqrt{(b+1-b)}$

$y^{\prime}=\frac{d y}{d x}=1$

Hence proved that the gradient of the curve at A is 1.

Adele opens an account with $100 and deposits $35 a month. Kent opens an account with $50 and also deposits $35 a month. Will th

Svetach [21]

Equations:

100 + 35m
50 + 35m

Steps:
100 + 35m = 50 + 35m 

Set the equations equal to each other.
 

100 + 35m = 50 + 35m 
-50 - 50

Subtract 50 from both sides of equation to isolate the variable on one side.

50+35m=35m
 -35m -35m

Subtract 35m from both sides of equation.

50=m

In fifty months, they will have the same amount of money. They will each contain $1850 dollars.

Hope this helps.

let length of the rectangle be l

length is 6 cm longer than the width, w

l = w + 6

perimeter of rectangle is 72 cm

= 2l + 2w

substitute l = w + 6

2(w+6) + 2w = 72

4w + 12 = 72

4w = 60

x = 15

ans is C. 15 cm
