if image of a point (4,6) under enlargement with centre (0,0) and scale factor 'k' is (2,3) find value of k
Answer:
k = 2
Step-by-step explanation:
2 x 2 = 4
3 x 2 = 6
so (2,3) multiplied by 2 will be (4,6)
Given that f(x) = 2x³-7x²+7ax+ 16 is divisible by x-a, find
(i) the value of the constant a
(ii) the remainder when f(x) is divided by 2x+1.
Answer:
a = - 2, remainder = 21
Step-by-step explanation:
The Remainder theorem states that if f(x) is divided by (x - a) the remainder is f(a)
Since f(x) is divisible by (x - a) then remainder is zero , then
f(a) = 2a³ - 7a² + 7a² + 16 = 0 , that is
2a³ + 16 = 0 ( subtract 16 from both sides )
2a³ = - 16 ( divide both sides by 2 )
a³ = - 8 ( take the cube root of both sides )
a = [tex]\sqrt[3]{-8}[/tex] = - 2
Then
f(x) = 2x³ - 7x² - 14x + 16
Evaluate f(- [tex]\frac{1}{2}[/tex] ) for remainder on division by (2x + 1)
f(- [tex]\frac{1}{2}[/tex] ) = 2(- [tex]\frac{1}{2}[/tex] )³ - 7(- [tex]\frac{1}{2}[/tex] )² - 14(- [tex]\frac{1}{2}[/tex] ) + 16
= 2(- [tex]\frac{1}{8}[/tex] ) - 7([tex]\frac{1}{4}[/tex] ) + 7 + 16
= - [tex]\frac{1}{4}[/tex] - [tex]\frac{7}{4}[/tex] + 23
= - [tex]\frac{8}{4}[/tex] + 23
= - 2 + 23
= 21

A bag contains 3 red balls and 5 green balls. What is the probability of picking a red ball from the bag AND getting heads upon flipping a fair coin
Answer:
the probability would be 3/8
Step-by-step explanation:
Since there are 3 red and 5 green, there is a total of 8 balls in the bag making it a chance of 3/8 to get a red ball. You're Welcome :) <3
Probability of picking a red ball is [tex]\frac{3}{8}[/tex]
Probability of getting head coin is [tex]\frac{1}{2}[/tex]
What is probability?"Probability is the possibility or chance of an event to occur." Ratio of number of favorable outcomes and total number of favorable outcomes is called probability.
We have,
Red balls = 3
Green balls =5
Formula for probability
[tex]\frac{Number of Favorable Outcomes}{Total Number of Favorable Outcomes}[/tex]
Total number of outcomes n(S) = 8
Number of favorable outcomes for getting a red ball n(E) = 3
Probability of picking a red ball
= [tex]\frac{Number of Favorable Outcomes}{Total number of Favorable Outcomes}[/tex]
= [tex]\frac{3}{8}[/tex]
We have a fair coin,
Total number of outcomes n(S) = 2
Number of favorable outcomes for getting head n(E) = 1
Probability of getting head coin
= [tex]\frac{Number of Favorable Outcomes}{Total Number of Favorable Outcomes}[/tex]
= [tex]\frac{1}{2}[/tex]
Hence, Probability of picking a red ball is [tex]\frac{3}{8}[/tex]
Probability of getting head coin is [tex]\frac{1}{2}[/tex].

Answer:
angle y=59 degrees
angle a= 62 degrees
Step-by-step explanation:
angle t =59
angle t=angle y(given)
therefore;
angle y=59 degrees
angle a +angle t +angle y=180(sum of the interior angles of a triangle)
a +59 +59 =180
a+118 =180
a =180-118
a = 62 degrees

1. Can the numbers 12, 6, 6 be used to form the sides of a triangle? Why or why not?
Answer: No, a triangle is not possible in this case
Why not? Because the two sides 6 and 6 add to 6+6 = 12, which does not exceed the remaining side.
Refer to the triangle inequality theorem. This theorem says that for a triangle to be possible, we need these three facts to be true
a+b > cb+c > aa+c > bwhere a,b,c are the three sides of the triangle. In short: adding any two sides must be larger than the third side.
I recommend cutting out slips of paper to try making a triangle with sides 12,6, and 6. You'll find its not possible. The two smaller sides combine to perfectly line up with the larger side. The three sides form a line and not a triangle.

The length of a rectangle is 22 meters. This is 8 more than twice of the width. Find the width of the rectangle
Answer:
w = 7
Step-by-step explanation:
L = 22
L = 2*w + 8
Since the Ls are the same thing, you can equate them
2w + 8 = 22 Subtract 8 from both sides
2w = 22 - 8 Combine
2w = 14 divide by 2
w = 14/2
w = 7
