1 meter = 100 cm
4 * 100 = 400
If there are 400 cm in 4 meters, we can use this equation to represent this problem:
d = day
4d = 400
Now, let's solve.
4d = 400
Divide both sides by 4.
d = 100
It will take 100 days for the sunflower to reach its maximum height of 4 meters/400 centimeters at 4 centimeters per day.
Answer:
$48.5
Step-by-step explanation:
Given data
Number of purses= 14+2= 16
Cost of 14 purses= $50
Cost of 2 purses= $38
Let us use the weighted cost method
Mean cost = (14*50+ 2*38)/16
Mean cost = (700+ 76)/16
Mean cost = 776/16
Mean cost =$48.5
Answer:
0.5
Step-by-step explanation:
there are 6 sides the probability of getting 3 is 3/6=1/2=0.5
<u><em>Answer:</em></u>
K = -47.5
<u><em>Explanation:</em></u>
The zero of an equation is a number that when substituted in the equation gives the result zero
<u>We are given that:</u>
4 is a zero of f(x) = 3x³ + kx - 2
<u>This means that:</u>
When we substitute x = 4 in f(x) the result will be zero
<u>Therefore:</u>
3(4)³ + k(4) - 2 = 0
<u>Now, we simply solve for K as follows:</u>
3(4)³ + k(4) - 2 = 0
3(64) + 4k - 2 = 0
192 + 4k - 2 = 0
190 + 4k = 0
4k = -190
k = -47.5
Hope this helps :)
A. Answer: y = 32.913(1.126)ˣ
<u>Step-by-step explanation:</u>
You are given two coordinates (2, 53) and (9, 122). Use these to create a system of equations:
53 = a(b)² and 122 = a(b)⁹
122 = a(b)²· (b)⁷
122 = 53 · (b)⁷
1.126 = b
Substitute the b-value into either of the equations to solve for "a":
53 = a(1.126)²
32.913 = a
Input the a- & b-values into the general form of an exponential equation:
y = a(b)ˣ
y = 32.913(1.126)ˣ
