Answer 1

Answer:

[tex]0.7 \ m/s^2[/tex]

Step-by-step explanation:

Acceleration:

From the graph, final speed = 9m/s

initial speed = 2 m /s

Time taken = 10 m

[tex]\sf \boxed{Acceleration=\dfrac{final \ speed - initial \ speed}{time \ taken}}[/tex]

[tex]\sf = \dfrac{9-2}{10}\\\\\\=\dfrac{7}{10}\\\\= 0.7 \ m/s^2[/tex]

What is the solution of a quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Given that, the roots of the quadratic equation are x= 2 + i.

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

A) x²-4x-5=0

Here, x=[4±√(16-20)]/2

x=[4±2i]/2

x=2±i

x=2+i or x=2-i

Therefore, option A is the correct answer.

10g -2=3

10g= -2+2=3+2

What is the answer to 2/6 + 1/2?

Answers

Answer: hey, there

your answer is 5/6

Step-by-step explanation:

2+3

Answer:

5/6

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/6, 1/2) = 6

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(26×11)+(12×33)=?

Complete the multiplication and the equation becomes

26+36=?

The two fractions now have like denominators so you can add the numerators.

Then:

2+36=56

This fraction cannot be reduced.

Therefore:

26+12=56

Solution by Formulas

Apply the fractions formula for addition, to

26+12

and solve

(2×2)+(1×6)6×2

=4+612

=1012

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(10,12) = 2

10÷212÷2=56

Therefore:

2/6+1/2=5/6

Answer:

C. [tex]1.18b[/tex]

Step-by-step explanation:

Hi! Ace here!

In order to do this, we have to convert 18% into a decimal.

The decimal form of it is .18.

So we have to do

[tex]b+.18b[/tex]

Combine like terms:

[tex]1.18b[/tex]

I hope this helped

Answer:

1.18b

Step-by-step explanation:

Remember: percentage = decimal × 100

total = b + 18% x b

Factor out b:

total = b x (1 + 18%) = b x (1 + 0.18)

total = b x 1.18 = 1.18b

What is the longest side of square that we can achieve? Write a function: class Solution { public int solution(int A, int B ) ; }that, given two integers A,B, returns the side length of the largest square that we can obtain. If it is not possible to create any square, the function should return 0 . Examples: 1. Given A=10,B=21, the function should return 7. We can split the second stick into three sticks of length 7 and shorten the first stick by 3 . 2. Given A=13,B=11, the function should return 5 . We can cut two sticks of length 5 from each of the given sticks. 3. Given A=2,B=1, the function should return 0 . It is not possible to make any square from the given sticks. 4. Given A=1,B=8, the function should return 2 . We can cut stick B into four parts.
