Answers
Answer:
m = -3
Step-by-step explanation:
Two poin on this line are (-2, 3) and (0, -3). Both points are formed where grid lines meet precisely.
The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6. Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.
a patient is advised to supplement her diet with 3g of calcium per day. The calcium tablets she purchases 300mg per tablet. How many tablets should the patient take per day?
Answers
Answer:
Number of tablet needed = 1 tablet
Step-by-step explanation:
Given:
Amount of calcium per day needed = 3 gram
Amount of calcium in a tablet = 300 mg
Find:
Number of tablet needed
Computation:
Number of tablet needed = Amount of calcium per day needed / Amount of calcium in a tablet
Number of tablet needed = 3gram / 300 milligram
Number of tablet needed = 300 milligram / 300 milligram
Number of tablet needed = 1 tablet

The only given function that is an exponential decay function is;
C: f(x) = ³/₂(⁸/₇)⁻ˣ
Exponential decay function
Now, the general formula for exponential decay function is;
f(x) = abˣ
where b is the decay factor.
Now, the decay factor which we will call the base of the exponent must be greater than 1 .
Also, the exponent x must be negative to be called an exponential decay function.
Looking at the given options, only Option C meets the criteria for an exponential decay function.
The given options are;
A) f(x) = ³/₄(⁷/₄)ˣ
B) f(x) = ²/₃(⁴/₅)⁻ˣ
C) f(x) = ³/₂(⁸/₇)⁻ˣ

Workers load 5 identical large crates and 3 identical small crates onto a freight elevator. The crates have a combined weight of 1375 pounds. Later
that day, the workers load 3 more identical large crates and 6 more identical small crates onto the freight elevator. These crates have a combined
weight of 1350 pounds.
What is the weight of each crate?
A. Each large crate weighs 185 pounds, and each small crate weighs 150 pounds.
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
C. Each large crate weighs 225 pounds, and each small crate weighs 112.5 pounds.
D. Each large crate weighs 250 pounds, and each small crate weighs 100 pounds.
Answers
Answer:
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
Step-by-step explanation:
Let L be the weight of the large crate and S the weight of the small crate.
Given that 5 identical large crates and 3 identical small crates have a combined weight of 1375 pounds,
5L + 3S = 1375 (1)
Also, in the second loading 3 identical large crates and 6 identical small crates have a combined weight of 1350 pounds,
3L + 6S = 1350 (2)
multiplying equation (1) by 2 and (2) by 1, we have
5L + 3S = 1375 (1) × 2
3L + 6S = 1350 (2) × 1
10L + 6S = 2750 (3)
3L + 6S = 1350 (4)
Subtracting (4) from (3), we have
7L = 1400
dividing through by 7, we have
L = 1400/7
L = 200
Substituting L = 200 into (1), we have
5L + 3S = 1375 (1)
5(200) + 3S = 1375 (1)
1000 + 3S = 1375
3S = 1375 - 1000
3S = 375
dividing through by 3, we have
S = 375/3
S = 125
So, each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
What is the length of side PR?
A. 8 cm
B. 11 cm
C. V105 cm
D. V176 cm
E. V274 cm
Answers
Answer:
D. √176 cm
Step-by-step explanation:
Were given a right triangle.
PQ = 7 cm
QR = 15 cm
To find the length of side PR, apply Pythagorean theorem, which is c² = a² + b²
Where,
c = hypotenuse/longest side = 15 cm
a = PR
b = 7 cm
Thus:
15² = PR² + 7²
225 = PR² + 49
225 - 49 = PR²
176 = PR²
√176 = PR
PR = √176 cm

What does the constant 0.2 reveal about the rate of change of the quantity?
the rate percentage
Answers
Answer:
80% decrease in the quantity over 7 days
Step-by-step explanation:
Given data
We have the function
f (t) = 310(0.2)24
the above function is similar to the exponential function
f (t) = P(1±r)^t
Now the value 0.2
This means that there is 80% decrease in the quantity over 7 days
A woman needs to work out how long it will take to drive to York.
She checks the journey on a website.

20 miles of the journey are through roadworks with a speed restriction of 40mph.
She should drive the rest of the journey at an average speed of 50mph
Answers
Answer:
It will take her 1hr 42mins.
Using the formula of speed, It will take 1 hour 42 minutes to drive to New York.
What is formula of speed?
The formula for Speed is given as [Speed = Distance ÷ Time].
The formula for time is given as [Time = Distance ÷ Speed ].
Time taken to drive to New York is :
= (20 miles / 40 mph) + ((80 - 20) miles /50 mph)
= 30 minutes + 1 hour 12 minutes
= 1 hour 42 minutes
