In the expression 852.763 x 10?, what is the missing exponent that would result in a number that is 1,000 times the value of 852
Molodets [167]

Answer:

The missing exponent = power of 3

852.763 x 10³ = 852763

Step-by-step explanation:

The expression 852.763 x 10?

A number that is 1,000 times the value of 852.763 is calculated as:

852.763 × 1000 = 852763

Converting this to exponent

852.763 × 10³ = 852763

Therefore, the missing exponent that would result in number that is 1,000 times the value of 852.763 is power of 3 meaning 10³

Which point is on the graph of f(x) = 3 x 5^x?
Harlamova29_29 [7]

Answer:

C

Step-by-step explanation:

To determine which point lies on the graph, substitute the x-coordinate into f(x) and if the value is equal to the y-coordinate then the point is on the graph

A (15, 1)

f(15) = 3 × 5^{15} ≠ 1 ← not on graph

B (0, 15)

f(0) = 3 × 5^{0} = 3 × 1 = 3 ≠ 15 ← not on graph

C (1, 15)

f(1) = 3 × 5^{1} = 3 × 5 = 15 ← lies on graph

D (0, 0)

f(0) = 3 × 5^{0} = 3 × 1 = 3 ≠ 0 ← not on graph

Bill has saved $825 from his last 8 paychecks. He saved either $75 or $150 a paycheck. Formulate and solve a system of equations
11Alexandr11 [23.1K]

Answer: 5 times

Step-by-step explanation:

Let the number of times that he saved $75 be x.

Let the number of times that he saved $150 be y.

Therefore, based on the information given in the question, we can form an equation which will be:

x + y = 8 ...... i

75x + 150y = 825 ....... ii

From equation I,

x + y = 8

y = 8 - x....... iiii

Put equation iii into ii and this will be:

75x + 150y = 825

75x + 150(8 - x) = 825

75x + 1200 - 150x = 825

75x - 150x = 825 - 1200

-75x = -375

x = 375/75

x = 5

He saved $75 5times from his paycheck.
