Answer:
Therefore the rate of growth of the tree is 33 cm/ yr.
Step-by-step explanation:
Given that,
The height of the tree is
H= 210 +33t
Here H represent the height of tree in cm and t is time in year.
The rate of growth is the first order derivative of the H with respect to time.
i.e The rate of growth 
∴H= 210 +33t
Differentiating with respect to t
Therefore the rate of growth of the tree is 33 cm/ yr.
Answer:
Answer is B) control group
Step-by-step explanation:
Survey is when you ask questions to a group of people. Has nothing to do in this case. Correlational does not exist but correlation means the association between two groups.
In an experiment, you apply a treatment, or a conditions that differentiates groups and measure an outcome . In this case the treatment is drinking alcohol to measure memory. The group that receives the treatment is the experimental group and the one that not receives the treatment is the control because, we are comparing or controlling alcohol consumption in this group to measure differences in memory with the experimental group.
I have a feeling your answer is:
m = 3/4
Sorry if it’s not right
Answer:
a)
Step-by-step explanation:
Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:
√75 = √3×25
√75 = √3×√25
√75 = √3 × 5
√75 = 5√3
a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25
b) Since √75 = 5√3
√75 = 5 × 1.7321
√75 = 8.6605
√75 = 8.661 {to nearest thousand}
Answer:
C) 30.9702
Step-by-step explanation:
Take log of both sides:
In5^x = In8^x - 7
Rewrite it using the laws of log:
xIn5 = (x - 7)In8
x / (x - 7) = ln 8 / ln 5
x / (x - 7) = 1.292
x = 1.292x - 9.044
1.292x - x = 9.044
x = 9.044 / 0.292
Thus, x = 30.9702
