Answer:

Step-by-step explanation:

Given that vector a has starting point (2,3) and end point (5,7)

Direction ratios of AB = (5-2, 7-3) = (3,4)

Magnitude = \sqrt{3^2+4^2} =5

a) Starting point (0,2)

Distance= 5 units from (0,2) and direction ratios (3,4)

So the point will be of them (0+3t, 2+4t)

Distance = 5t units.  So t =1

So point is (3,6)

b) When starting point =(0,5)

End point with same direction would be

(0+3, 5+4) = (3,9)

1+9x14+12=? please help fast
Klio2033 [76]

Answer:

139

Step-by-step explanation:

So we start with PEMDAS. (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.)

Since we don't have parenthesis or exponents, we can go straight to multiplication. 9 multiplied by 14 is 126.

Now we go to addition. 126+1=127

127+12=139

Hope I helped :)

Ksju [112]
25 kids in all
2xboys:3x girls
 
so the equation would be 
2x+3x=25
solve,
5x=25
/5           /5
x=5
2x=10
3x=15


10 boys and 15 girls

a right triangle has legs of length 3x m and 4x m and hypotenuse of length 75 m. find the lengths of the legs of the triangle
just olya [345]
It is a 3-4-5 right triangle

leg1 := 3x, leg2:=4x, hypotenuse:=5x

given hypotenuse = 75m
=> 5x=75
So, x= 75÷5 = 15
Therefore, leg1 = 3(15) = 45m.
leg2= 4(15) = 60m.

3. In a game, if you roll a 6 on a 6-sided number cube, you lose a turn.
dlinn [17]
Part A: The probability is 1/6. This is because there are six options in total, and only one of those options is 6.

Part B: The probability is 6/6, or alternatively 100%. This is because that the probability of rolling a 6 is 1/6, and the probability of rolling any of the other options is 5/6. Adding them together gives a probability of 6/6.

Part C: The probability is 5/6. This is because there are six options, and of those, five of them are not 6.
