How many whole numbers are there with not more than 4 digits?

2 answers:

7 0

I think its 1000 numbers because there from 1 to 999 there are 999 numbers, and then you add zero because it is also a whole number.

A digit is a symbol that is used to write numbers. We use the whole number digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. We can use these digits to write any number.

0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are one digit numbers.

So total number of one digit number = 10

All the numbers from 10 to 99 are two digit numbers.

So total number of two digit numbers = 90

All the numbers from 100 to 999 are three digit numbers.

So total number of three digit numbers = 900

All the numbers from 1000 to 9999 are four digit numbers.

So total number of four digit numbers = 9 000

whole numbers are there with not more than 4 digits = 10 + 90 + 900 +9000 = 10,000

Find the number of terms and the degree of this polynomial.

Hatshy [7]

Answer:

Number of terms = 3

Degree = 6

Step-by-step explanation:

A polynomial is a mathematical expression that gives the detailed combination of variables with their coefficients, their positive exponential, and other variables using the operations of subtraction, addition, and multiplication

The number of terms in a polynomial is the number of different powers of added or subtracted in the expression

Therefore, the number of terms in the expression -3·s⁶ + 2·s⁴ + 3·s³ is 3 terms

Number of terms = 3

The degree of a polynomial is given by the highest power of the variables in the polynomial. Therefore, the degree of the given polynomial is 6

Degree = 6

Find the area of the triangle formed by the origin and the points of intersection of parabolas y=− 1/3 (x−1)^2+8 and y=x^2−2x−3.

Kobotan [32]

Answer:

The area of the triangle formed by origin, and the points (4,5) and (-2,5) will be 15 sq. units.

Step-by-step explanation:

The two parabolas are $y = - \frac{1}{3}(x - 1)^{2} + 8$ and y = x² - 2x - 3.

Now, solving those two equations we will get the points of intersection.

So, $- \frac{1}{3}(x - 1)^{2} + 8 = x^{2} - 2x - 3$

⇒ - (x - 1)² + 24 = 3x² - 6x - 9

⇒ -x² + 2x - 1 + 24 = 3x² - 6x - 9

⇒ 4x² - 8x - 32 = 0

⇒ x² - 2x - 8 = 0

⇒ x² - 4x + 2x - 8 = 0

⇒ (x - 4)(x + 2) = 0

So, x = 4 or - 2.

Now, for x = 4 , y = 4² - 2(4) - 3 = 5 and the point of intersection is (4,5).

Or, for x = - 2, y = (- 2)² - 2(- 2) - 3 = 5 and the point of intersection is (-2,5).

Now, points (4,5) and (-2,5) make a straight line parallel to the x-axis at a perpendicular distance of 5 units from origin and its length is (4 - (- 2)) = 6 units.

So, the area of the triangle formed by origin, and the points (4,5) and (-2,5) will be = 0.5 × 5 × 6 = 15 sq. units. (Answer)
