Which answer is a reasonable estimate to the following problem? 94 · 689
60,000
70,000
600,000
700,000
The reasonable estimate for multiplying 94 by 689 is found by rounding the numbers to the nearest convenient figures, which gives an estimated result of 70,000.
Explanation:To estimate the product of 94 and 689, you can round each number to its nearest simple form and then multiply. Round 94 to 100 because it is close to that multiple of ten. Round 689 to 700, as it is close to this hundred mark. When you multiply 100 by 700, you get 70,000.
This process of rounding to the nearest convenient number simplifies the multiplication and gives us an answer that is easy to calculate and understand. Hence, by rounding the numbers before multiplying, the reasonable estimate for the problem 94 · 689 is 70,000.
Final answer:
By rounding the numbers and multiplying, a reasonable estimate for the product of 94 and 689 is 70,000.
Explanation:
To estimate the product of 94 · 689, we can round the numbers to the nearest ten or hundred and then multiply. For estimation purposes, we can approximate 94 to 100 (since it's closer to 100 than 90) and 689 to 700 (since it's closer to 700 than 600).
Multiplying these rounded figures: 100 × 700 equals 70,000. Therefore, 70,000 is a reasonable estimate for the product of 94 and 689.
A fireman, 57.6 m away from a burning building, directs a stream of water from a fire hose at an angle of 35.2° above the horizontal. if the initial speed of the stream is 42.7 m/s, at what height will the stream of water strike the building?
First calculate the time it takes to reach the building using the x-component of the velocity.
t = 57.6 m / (42.7 m/s * cos35.2) = 1.65 s
Then we calculate the height y using the y-component of the velocity:
y = (42.7 m/s * sin35.2) * 1.65 s – 0.5 (9.81 m/s^2) (1.65 s)^2
y = 11.26 m
Final answer:
Using principles of projectile motion and given the initial speed, angle of projection, and horizontal distance, the stream of water from the fire hose will strike the building at a height of approximately 20.3 meters.
Explanation:
To determine at what height the stream of water will strike the building, we need to apply the principles of projectile motion. We are given the initial speed of the water stream (42.7 m/s), the angle of projection (35.2 degrees), and the horizontal distance from the fireman to the building (57.6 meters).
First, we separate the initial velocity into horizontal (ux) and vertical (uy) components:
ux = u * cos(θ) = 42.7 m/s * cos(35.2°) = 42.7 m/s * 0.8192 ≈ 35.0 m/s
uy = u * sin(θ) = 42.7 m/s * sin(35.2°) = 42.7 m/s * 0.5759 ≈ 24.6 m/s
Next, we use the formula for the horizontal motion to find the time (t) it takes for the water to reach the building:
x = ux* t => 57.6 m = 35.0 m/s * t => t ≈ 1.65 s
Finally, we can calculate the vertical distance (y) using the time and the vertical component of the velocity:
y = uy*t - (1/2) * g * t2 = 24.6 m/s * 1.65 s - (0.5 * 9.81 m/s2 * (1.65 s)2) ≈ 20.3 m
Therefore, the stream of water will strike the building at a height of approximately 20.3 meters above the ground.

Dr. Hong prescribed 0.019 liter more medicine than Dr. Tannenbaum. Dr. Evans prescribed 0.02 less than Dr. Hong. Who prescribed the most medicine. Who prescribed the least
Who prescribed the
most medicine?
It would be Dr. Hong. This is because Dr. Hong has prescribed more than Dr.Tannenbaum and Dr.Evans.
Who prescribed the least?
It would be Dr.Evans. Because he has prescribed 0.02
less than Dr.Hong and 0.01 less than Dr.Tannenbaum.
Dr. Hong prescribed most medicine and Dr. Evan prescribed less medicine among all other doctors.
Further explanation:
Given:
Dr. Hong prescribed 0.019 liter more medicine than Dr. Tannenbaum.
Dr. Evans prescribed 0.02 liter less than Dr. Hong.
Calculation:
Consider Dr. Tannenbaum prescribed x liter medicine.
It is given that the Dr. Hong prescribed 0.019 liter more than the Dr. Tannenbaum.
Therefore Dr. Hong prescribed [tex]x+0.019{\text{liter}}[/tex] medicine.
It is also given that the Dr. Evans prescribed 0.02 liter less than Dr. Hong.
Therefore, Dr. Evans prescribed [tex]\left({x+0.019-0.02}\right){\text{liter}}[/tex] medicine.
So the Dr. Evans prescribed exactly [tex]\left({x-0.001}\right){\text{liter}}[/tex].
Therefore the medicine prescribed by Dr. Hong is [tex]\left({x+0.019}\right){\text{liter}}\\[/tex].
The medicine prescribed by Dr. Tannenbaum is x liters.
The medicine prescribed by Dr. Evans is [tex]\left({x-0.001}\right){\text{liter}}[/tex].
Arrange all doctors in ascending order with their prescribed medicine.
Dr. Hong > Dr. Tannenbaum > Dr. Evans
So it is obtained from the above expression that the Dr. Evans prescribed less medicine and Dr. Hong prescribed most medicine than other doctor.
Thus, Dr. Hong prescribed most medicine and Dr. Evans prescribed less medicine among all other doctors.

find two consecutive integers such that the larger is nine more than twice the smaller
Two consecutive integers are - 7 and - 8.
Here,
We have to find the two consecutive integers.
What are Integers?
An integer is a number which includes negative and positive numbers, including zero.
Now,
Let the smaller number is x.
Then, the larger is nine more than twice the smaller.
So, Larger number = 2x + 9
Since, The difference of two consecutive number are always 1.
So,
2x + 9 - x = 1
x + 9 = 1
x = -8
Therefore, The larger number = 2x + 9 = 2*-8 + 9 = -16 + 9 = -7
Hence,
Two consecutive integers are - 7 and - 8.

What is the domain of f(x) = 3x?
Answer:
C. All real numbers.
Step-by-step explanation:
We have been given a function [tex]f(x)=3^x[/tex]. We are asked to find the domain of our given function.
We know that domain of a function is all values of x for which a function is real and defined.
We know that the domain of an exponential function is all real values of x that is [tex](-\infty,\infty)[/tex].
Since our given function is an exponential function, therefore, domain of our given function is all real numbers.
The domain of a function is the set of input values the function can take.
The domain of f(x) = 3x is (c) all real numbers
The function is given as:
[tex]f(x)=3x[/tex]

A. y=-2x+23
B. y=2x+11
C. y=-3x+26
D. y=2x-11
Answer:
B
Step-by-step explanation:
To write the equation of the line, use the slope formula to find the slope. Then substitute the slope and a point into the point slope form. Simplify using the distributive property to write in slope intercept form.

Compute, in centimeters and in meters, the height of a basketball player who is 6 ft 6 in. tall.
Answer:
Height in cm =198.12 cm
Height in m =1.9812 m
Step-by-step explanation:
To make this conversion we have to get the conversion rate from feet and inches to centimeters.
Each feet is 30.48 cm. And each inch is 2.54 cm This is the rate of conversion.
So, to get the height of the basketball player we have to multiply the height in feet and inches by the rate.
6 ft x 30.48 cm= 182.88 cm
6 in x 2.54 cm= 15.24 cm
Adding both, height in cm =198.12 cm
Rate of conversion cm to m= 100 cm are a meter
We divide the height in cm by 100 to get the height in m
Height in m =1.9812 m
