F(x)= -x2 + 1 for x =-3

Mathematics
1 answer:
dalvyx [7]3 years ago
8 0

Answer:

f(-3) = -8

Step-by-step explanation:

It is given that f(x) = - x² + 1. Find the value of f(x) by substituting x = -3 into f(x)

f(x) = - x² + 1

f(-3) = -(-3)² + 1

= -9 + 1

= -8

Deepak wrote out the steps to his solution of the equation startfraction 5 over 2 minus 3 x minus 5 plus 4 x equals negative sta
andre [41]

The solution is x=3/4

How can we solve given equation?

First, we will solve like terms. Then shift constant to other side and keep x on the same side to get the value of x.

We can solve given equation as shown below:

5/2-3x-5+4x=-7/4

(5-10)/2+x=-7/4

-5/2+x=-7/4

x=5/2-7/4

x= (10-7)/4

x=3/4

Hence, the solution is x=3/4.

Which system about this figure is true?
jok3333 [9.3K]

Answer:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

  TRUE, it has rotational degree, FALSE, angle of rotation is 180 degrees

2)It has no reflection symmetry.  FALSE

3)It has reflection symmetry with many planes of symmetry. TRUE

4)  It has no rotational symmetry. FALSE

Step-by-step explanation:

Rotational Symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Symmetry Order = Number of turns it takes to get to its similar position.

Reflected Symmetry : When a line is drawn which divides the shape in to two equal halves it is called reflective symmetry.

Consider the given figure:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

  TRUE, it has rotational degree.

FALSE,  it regains its identical shape in 90 degrees, it is in  180 degrees.

2)It has no reflection symmetry.

FALSE, the given figure has reflection symmetry along both horizontal and vertical axis.

3)It has reflection symmetry with many planes of symmetry.

TRUE, it has inflectional symmetry in Horizontal as well a in vertical plane.

4)  It has no rotational symmetry.

FALSE, it has a rotational  symmetry of ORDER 2

Michael is planning to invest his 2,000 into a bank account between investment A with 8% simple interest or investment B with 6%

The investment with the bigger return is investment B.

<h3>What is simple interest and compound interest?</h3>

Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued. This differs from compound interest where the debt holder pays interest on the principal and the interest rate already accrued

<h3>What is the compound interest?</h3>

The formula for calculating future value:

FV = P (1 + r)^n

  • FV = Future value
  • P = Present value
  • R = interest rate
  • N = number of years

2000 x (1.06)^12 = $4024.39

Compound interest =  $4024.39 - $2000 =  $2024.39

<h3>What is the simple interest? </h3>

Simple interest = principal x time x interest rate

2000 x 0.08 x 12 = $1920
