Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 17)(0,17) and (2, 1700)(2,1700).
Answers
Answer:
y = 17 · 10ˣ
Step-by-step explanation:
We can already get some idea of what this function might be by looking at what happens to the y value as we increase the x value of the function. We start at x = 0 with y = 17, and increasing x by 2 to x = 2 makes y = 1700. Notice that by increasing x by 2, we've added two zeroes to the end of 17. The only number which has this property in the decimal system is 10, so that must be our base, and our initial value must be 17. So our function is
[tex]y=17\cdot10^x[/tex]
We can verify this by running each of those points through the equation:
[tex]17=17\cdot10^0=17\cdot1=17\\1700=17\cdot10^2=17\cdot100=1700[/tex]

Given:
On their farm, Doug and Elizabeth created a garden.
They wish to increase its dimensions by 50% without changing the shape of the garden.
If the length of the garden is now 40 feet long.
Then increased by 50% means,
100 + 50 = 150%.
In decimals,
150% = 1.5
The length of the new garden is,
= 40 x 1.5
= 60 feet.
Therefore, the length is 60 feet.

which point of concurrency is the center of gravity in a triangle
Answers
Reasoning: The centroid is the point of concurrency of the three medians in a triangle.
The centroid is the point of concurrency of gravity in a triangle.
What is centroid?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians converge.
Since, the center of the gravity of the triangle is a point where a triangle is totally balanced.
The point of concurrency of the center of gravity of a triangle is a point where all three medians meet, and this point is called centroid.
Hence, centroid is the point of concurrency of gravity in a triangle.

in a class of 32 students the mean height of the 14 boys is 1.56 meters and the mean height of all 32 students is 1.151 meters. work out the mean height of girls
Answers
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48

1/4 because it’s 5/20 and 1/5 is 4/20
they are both the same because 3/4 is the same as 18/24
hope that helps!
Answer:
15) 2/5
16) 1/4
17) Same
Step-by-step explanation:
15) Multiply 2/5 by 2 on both the numerator and denominator which is 4/10 now you can clearly tell that 2/5 is greater.
16) Multiply 1/5 by 4 on both the numerator and denominator and multiply 5 on both the numerator and denominator in 1/4 for 1/4 you will get 5/20 and for 1/5 you will get 4/20 and you can tell that 5/20 is greater which is 1/4.
17) Multiply 3/4 by 6 on both the numerator and denominator you will get 18/24 so 18/24 and 3/4 are equivalent.

What property of operations will be used to simplify the product of a binomial and trinomial? *
Answers
Answer:
Distributive property.
Step-by-step explanation:
A distributive property is a rule that states that, multiplying two factors such as a binomial and trinomial would give the same result as multiplying the sum of two addends by the other factor.
Hence, the distributive property is used to simplify the product of a binomial and trinomial.
For example, let's find the product of (2x + 4)(5x² + 3x + 10)
First of all, we would distribute trinomial into each of the term in the binomial.
2x(5x² + 3x + 10) + 4(5x² + 3x + 10)
Distributing the monomial into the trinomial, we have;
2x(5x²) + 2x(3x) + 2(10) + 4(5x²) + 4x(3x) + 4(10)
Expanding the bracket, we have;
10x³ + 6x² + 10 + 20x² + 12x² + 40
Collecting like terms, we have;
10x³ + (6x² + 20x² + 12x²) + 10 + 40
10x³ + 38x² + 50
Therefore, (2x + 4)(5x² + 3x + 10) = 10x³ + 38x² + 50
