Answer 1

Answer:

f(-6) = -2

Step-by-step explanation:

plug in k value (-6)

f(-6) = -6/2 + 1

theres two ways to solve for this

one way:

convert the whole number 1 to an improper fraction

f(-6) = -6/2 + 2/2

combine like terms

f(-6) = -4/2

divide -4 by 2

f(-6) = -2

second way:

divide -6 by 2

f(-6) = -3 + 1

combine like terms

f(-6) = -2

either way you get the same answer

use whichever is easiest for you

What is the image point of (-2,5)(−2,5) after a translation left 5 units and up 3 units?

Answers

Answer:

(-7;8)

..........................

The image point will be (-7, 8)

What is translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.

The direction or the path of this change in position of the object can vary i.e., initially the object can move left, then turn right, and so on. While translating, all the points on the shape will shift by the same number of units. For example, if one point shifts 2 units to the right, then all the points will also move 2 units to the right.

Given:

coordinate ( -2, 5)

To translate 5 units left the x- coordinate will be

= -2 -5

= -7

and, now to shift 3 units up y- coordinate will be

=3+5

=8

Hence, the image point will be ( -7 , 8)

Determine the amount of an investment if AED 300 is invested
at a rate of 3.5% interest compounded monthly for 22 years.
A. 319.85 AED
B. 647.20 AED
C. 639.45 AED

Answers

Answer:

C. 639.45 AED

Step-by-step explanation:

Principal  = AED 300

Compound interest = 3.5%

Unknown:

Amount of the investment after 22yrs = ?

Solution:

Compound interest is simply interest on interest.

  The formula is given as;

           A  = P(1 + [tex]\frac{r}{n})^{nt}[/tex]

where A is the final amount

            P = initial principal

            r = interest rate

           n = number of years

 Input the parameters and solve;

          A  = 300 (1 + [tex]\frac{0.035}{1} )^{22 x 1}[/tex]

          A  = 639.45

So the amount of investmet is AED 639.45

b. Joey paid at least P2,000 for the shirt and pants.The cost of pants is P700 more than the shirt.

c. A garden's length is 7m longer than its width and the area is 18 square meter.

d. A lot costbP4,000 per square meter and the area is 120 square meters.

Answer:

C.

Step-by-step explanation:

Required

Determine which option answers the question, correctly.

From the list of given options, only option c answers the question correctly.

This is shown below.

Represent

Length with l and Width with w, such that:

[tex]l = 7 + w[/tex]

Area (A) is calculated as thus:

[tex]A = l * w[/tex]

Substitute 7 + w for l and 18 for A.

This gives:

[tex]18 = (7 + w) * w[/tex]

Open Bracket

[tex]18 = 7w + w^2[/tex]

Reorder

[tex]w^2 + 7w = 18[/tex]

Subtract 18 from both sides

[tex]w^2 + 7w - 18= 18 - 18[/tex]

[tex]w^2 + 7w - 18= 0[/tex]

See that the above expression is a quadratic equation.

[tex]d = 4\sqrt{2}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-4-0)^2+(-4-0)^2}[/tex]

[tex]d = \sqrt{(-4)^2+(-4)^2}[/tex]

[tex]d = \sqrt{16+16}[/tex]

[tex]d = \sqrt{32}[/tex]

[tex]d = 4\sqrt{2}[/tex]
