The midpoint of FG is (6-4) and the coordinates of point Fare (-3, 6) What are the coordinates of point G?

lora16 [44]

Answer:

(15,-14)

Step-by-step explanation:

Given that,

The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).

Let (x,y) be the coordinates of point G. Using mid point formula,

$\dfrac{x+(-3)}{2}=6\ \text{and}\ \dfrac{y+6}{2}=-4\\\\x-3=12\ \text{and}\ y+6=-8\\\\x=15,\ \text{and}\ y=-14$

So, the coordinates of G are (15,-14).

Robert threw a rock off a bridge into the river. The distance from the rock to the river is modeled by the equation h=-16ť – 16t

cluponka [151]

Answer:

1.5 seconds

Step-by-step explanation:

h=-16t² – 16t+ 60

When the rock enter the water, the height is 0. ... h=0

0 = -16t² – 16t+ 60 = -4 * (4t² - 4t +15) = -4* (2t - 3) (2t +5)

2t-3=0 or 2t+5 = 0

t = 3/2 or t = -5/2 (time can't be negative)

t = 3/2 or 1.5

What are the first three terms of the sequence represented by the recursive formula

Dimas [21]

Answer: B. 0.25, 3.75, 5.2

Step-by-step explanation:

Since, the given sequence, $a_n= n^2 -a_{n-1}$

And, $a_5=14\frac{1}{4}$

On substituting n=5 in the given recursive formula,

We get, $a_5=5^2-a_{5-1}\implies a_5=25-a_4\implies 14\frac{1}{4}= 25-a_4\implies a_4=10\frac{3}{4}$

For, n=4 $a_4=4^2-a_{4-1}\implies a_4=16-a_3\implies 10\frac{3}{4}= 16-a_3\implies a_3=5\frac{1}{4}\implies a_3=5.25$

For, n=3 $a_3=3^2-a_{3-1}\implies a_3=9-a_2\implies 5.25= 9-a_2\implies a_2=3.75$

For, n=2 $a_2=2^2-a_{2-1}\implies a_2=4-a_1\implies 3.75= 4-a_1\implies a_1=0.25$

Thus, First second and third terms are,

$a_1=0.25$ , $a_2=3.75$ and $a_3=5.25$ .

What is 6x^2-x-2 when factoring

lidiya [134]

6x^2-x-2 this is of the form ax^2+bx+c

jk=ac=-12 and j+k=b=-1 so j and k must be -4 and 3 so

6x^2+3x-4x-2

3x(2x+1)-2(2x+1)

(3x-2)(2x+1)
