F(x) = x^2 is the black parabola in both graphs.
g(x) = - 7/2 x^2 tells you the parabola will be:
- flipped upside down because the negative on the 7/2
- skinnier, because of the 7/2.

This will be the second graph.

Answer:

b=2√7 ≈ 5.29 meters

Step-by-step explanation:

think of it like a right triangle like in the picture with 8metre ladder as the hypotenuse

a²+b²=c²

6²+b² =8²

b²= 8²-6²=28

b=√28 =2√7 ≈ 5.29 meters

Write down in terms of n an expression for the nth term of the following sequence. A) 25,20,15,10,5

ExtremeBDS [4]

Answer:

(30-5n)

Step-by-step explanation:

The given sequence is :

25,20,15,10,5

Here,

First term, a = 25

Common difference = 20-25 = -5

We need to find the nth term of the given sequence. The formula for the nth term is given by :

$a_n=a+(n-1)d\\\\a_n=25+(n-1)(-5)\\\\=25-5n+5\\\\=30-5n$

So, the nth term of the above sequence is (30-5n).

HELP PELASE ILL MARK BRAINLIEST AND POINTS!

UNO [17]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.

and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.

that is ~

$\qquad \sf \dashrightarrow \: x + y = 3$

put y = - 2,we will get :

$\qquad \sf \dashrightarrow \: x - 2 = 3$

$\qquad \sf \dashrightarrow \: x = 5$

so, 1st equation satifys the condition. let's check out 2nd one.

$\qquad \sf \dashrightarrow \: x + 2y = 1$

put y = -2

$\qquad \sf \dashrightarrow \: x + (2 \times - 2) = 1$

$\qquad \sf \dashrightarrow \: x - 4 = 1$

$\qquad \sf \dashrightarrow \: x = 5$

Hence, we can conclude that the Correct choice is D
