What is the value of f(-3) when f(x)=5(2)

Answers

Answer:

a) 5/8

Step-by-step explanation:

f(-3) when f(x)=5(2)^x just replace the x with -3

f(x)=5(2)^x = 5 (2)^-3 we find the 3rd power of 2 first which means multiply 2 with itself 3 times

2×2×2 = 8 but here, it asks us for negative third power of 2 so we turn the 8 upside down :

if 2^3 = 8 then 2^-3 = 1/8 and now we multiply it with 5

5 × 1/8 = 5/8

What is the solution to the system of equations?
x = -4y
3x + 2y = 20

Answers

Answer:

(x, y) = (8, -2)

Step-by-step explanation:

Substitute:

3(-4y) + 2y = 20

-12y + 2y = 20

-10y = 20

y = -2

x = -4(-2) = 8

From the top of the tower 30 m height a man is observing the base of a tree at an angle of depression measuring 30 degree. Find the distance between the tree and the tower.
Please show your work

Answers

Answer:

  30√3 m ≈ 52 m

Step-by-step explanation:

The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.

The distance between the tree and the tower is about 30√3 m ≈ 52 m.

__

If you haven't memorized the ratios of this special triangle, you can use the relation ...

  Tan = Opposite/Adjacent

  tan(30°) = 30/d

  d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

FIND THE AREA (LEAVE EXPLANATION)

Answers

Answer:

20 yd²

Step-by-step explanation:

lets do the big one

4 x (6-2) = 4 x 4 = 16 yd²

2 x (4-2) = 2x2 = 4 yd²

16 yd² + 4 yd² = 20 yd²

Another way

Find the area of the figure if it was a rectangle

4 x 6 = 24 yd²

then subtract 2 x 2 = 24 yd² - 4 yd² = 20 yd²

Answer:

20

Step-by-step explanation:

Solve the area of the squares separately, then add. the small square has a length and width of 2, and 2x2 is 4, so that area is 4. the bigger one has a length and width of 4, and 4x4 is 16, and then we add the two values together, and 16+4 is 20, so the total area is 20.

Answer:

  (b)  2 years

Step-by-step explanation:

The interest formula is ...

  I = Prt . . . . interest rate r on principal P for t years

We can fill in the known values and solve for t.

  60 = 750·0.04·t

  60/30 = t = 2

The loan was repaid in 2 years.

Answer:

function b

Step-by-step explanation:

When its asking for which function has a greater rate of change its asking for which slope has a greater value

the slope is calculated by change in y over change in x

for function a, as y goes up 2 x goes up 1

so the slope ( rate of change) is 2/1

for function b is y goes up 3 x goes up 1

so the slope (rate of change) is 3/1

3/1 is greater than 2/1 so function b has a greater rate of change

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning. The lcm of two numbers is the product of the two number discuss your conclusion with a partner

Answers

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as [tex]7,8[/tex]

LCM of [tex]7,8=7(8)=56[/tex]

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as [tex]6,3[/tex]

[tex]6=3(2)[/tex]

So,

LCM of [tex]6,3=3(2)=6[/tex]

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.
