Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3?

Mathematics
1 answer:
Zarrin [17]3 years ago
3 0

Answer:

The coordinate B' is B' = (3, -3).

Step-by-step explanation:

The new coordinate is computed by applying the scale factor with respect to origin:

B' = \alpha \cdot B

B' = 3\cdot (1,-1)

B' = (3\cdot 1, 3 \cdot (-1))

B' = (3, -3)

There are over 2700 species of snakes in the world over 600 are venomous Express the fraction of species that are not venomous a
Andre45 [30]
You do 600 divided by 2700 and you end up with 22/100 or 0.22 as a decimal. So if 0.22 or 22/100 are venimous then 78/100 or 0.78 are non venimous. I understand its a bit confusing and i can simplify it for you but still I hope this helps :)

The probability that it will be warmer today than it was yesterday is 0.1.
Vikki [24]

Answer:

a) 30% probability that it will not be colder today than it was yesterday

b) 90% probability that it will not be warmer today than it was yesterday

Step-by-step explanation:

In this question, we have that:

0.1 = 10% probability it will be warmer today than yesterday.

0.7 = 70% probability it will be colder today than yesterday.

a .What is the probability that it will not be colder today than it was yesterday?

70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.

b What is the probability that it will not be warmer today than it was yesterday?

10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Functions
  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -2x² + 3x - 6

f(3) is x = 3 for the function f(x)

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function]:                                                                                f(3) = -2(3)² + 3(3) - 6
  2. Exponents:                                                                                                        f(3) = -2(9) + 3(3) - 6
  3. Multiply:                                                                                                             f(3) = -18 + 9 - 6
  4. Add:                                                                                                                   f(3) = -9 - 6
  5. Subtract:                                                                                                            f(3) = -15

Write in slope-intercept form the equation of the line passing through the given point and perpendicular to the given line.
Ksivusya [100]

Answer:

y = x + 1

Step-by-step explanation:

First you find the slope of the first line using the rise over run method. Here you can see that the line goes up 1 and to the right one in order to reach the next point making the slope 1x or just x. Then you need to make it so that the line intercepts the point by changing the y intercept to 1 making the equation y = x + 1.

I hope this helped!!
