An exponential function, f(x), passes through the points (2,5) and (8,20). Determine the value of f(25) to the nearest integer.

Answers

Answer:

assume: f(x) = A(bx); then: f(8) = A(b8) = 20;

and: f(2) = A(b2) = 5

dividing the first equation by the second equation gives: b6 = 4; or: b = 4(1/6) = 1.26;

then: A(1.262) = 5; or: A = 5/(1.262) = 3.15; then: f(x) = 3.15(1.26x);

so that: f(25) = 3.15(1.2625) = 1017.6 ---> 1018

If 2^2x = 2^3, what is the value of x?

Answers

Answer:

X = 3/2.

Step-by-step explanation:

Please refer to the attachment given above.

The value of x in the equation 2[tex]^{(2x)}[/tex] = 2³ is 1.5.

To find the value of x in the equation 2[tex]^{(2x)}[/tex] = 2³, we can use the property of exponents that states: If two exponential expressions have the same base and are equal, then their exponents must be equal.

In this case, we have 2[tex]^{(2x)}[/tex] = 2³. Since the bases are the same (both are 2), we can equate the exponents:

2x = 3

Now, to solve for x, divide both sides by 2:

x = 3/2

So, the value of x is 3/2 or 1.5.

Parking lots A and B each charge a set fee for parking plus an hourly rate.

Hours Parked48Lot A Cost ($)19.00/33.00

Lot B Cost ($)20.00/32.00

How many more dollars does it cost per hour to park in Lot A than in Lot B? Give the answer as a decimal showing dollars and cents.

Answers

Answer:

$0.5

Step-by-step explanation:

Given :

Hours ___Lot A Cost ($) ___ Lot B Cost ($) 4____________19.00 _____ 20.00

8 ___________ 33.00 ______ 32.00

Using the equation :

y = mx + C

m = slope = Hourly charge

C = intercept = set park fee

m = y2 - y1 / x2 - x1

For LotA:

m1 = (33 - 19) / (8 - 4)

m1 = 14 / 4

m1 = 3.5

For LotB:

m2 = (32 - 20) / (8 - 4)

m2 = 12 / 4

m2 = 3

Since, m is the hourly cost :

Difference = m1 - m2

= 3.5 - 3

= $0. 5

A walkway goes through the middle of a square playground from one corner to the opposite corner. If the walkway is 20 meters long, how long are each of the sides of the playground? Round your answer to the nearest hundredths.

Need Help!

Answers

I think you would use the Pythagorean Theorem to solve this, as a square cut across diagonally creates two isocele triangles. Since the longest side is 20 m, this value would be imputed into c^2.

a^2 + b^2 = c^2
a^2 + a^2 = 20^2
2a^2 = 400
2a^2/2 = 400/2
a^2 = 200
a = 14.14

Thus, each sides of the playground are 14.14 meters long.

The area of triangle xyz is 35 cm. the height is 10cm. what is the base of the triangle?

Answers

Area of Triangle=1/2(h x b)
35=1/2(10 x b)
35=5 x b
35=5b
7cm=b is the base of the triangle

Answer:

Base of the triangle = 7 cm

Step-by-step explanation:

Given information,

→ Area of triangle = 35 cm

→ Height = 10 cm

Now we have to,

→ Find the base of the triangle.

Formula we use,

→ Area = ½ × b × h

Forming the equation,

→ (1/2) × b × 10 = 35

Then the value of b will be,

→ (1/2) × b × 10 = 35

→ (b × 10)/2 = 35

→ 10b/2 = 35

→ 10b = 35 × 2

→ 10b = 70

→ b = 70/10

→ [ b = 7 cm ]

Hence, the value of b is 7 cm.
