Answer:
Explanation:
This is an exponential growing: there is a constant growing<em> factor </em>which multiplies the value number of letters sent every week.
The growing factor <em>4 letters every 9.1 weeks</em> means that every 9.1 weeks the number of letters is multiplied by 4.
Then, if the number of weeks is t, the number of times the number of letters increase is t/9.1.
Then, the exponential<em> function</em> <em>that models the number of people who receive the email t weeks since Tobias initially sent the chain letter</em>, has the form:
<em>Tobias initially sent the chain letter to 37 friends</em>; thus, the initial value is 37, and the complete function is:
, where t is the number of weeks since Tobias initially sent the chain letter.
There are no choices so I’m going to assume this is simplification.
Answer:
3/4 —> this is the most simplified version of that fraction.
Explanation:
48/64 can be divided by multiple things to gain fractions. You could divide it by 2 repeatedly until arriving to a fraction wherein you couldn’t split anymore.
Ex.) 48/64 = 24/32 = 12/16 = 6/8 = 3/4
All of the above answers are equivalent to 48/64.
An easier way to reach the final answer of 3/4 would be to find the greatest common factor of 48/64. You can divide both by 16 and then get to 3/4.
Hope this helps!
Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
It’s just like solving a positive fraction find a common denominator and Add or subtract
