We are given the series of <span>a1 = -5 a2 = 20 a3 = -80. In this case, we can see that this is a geometric sequence with a geometric ratio equal to 20/-5 = -80/ 20 or equal to 4. Hence, r is equal to 4, a1 is equal to -5.
The geometric sequence formula is an = a1*r^(n-1) = -5 * (-4)^ (n-1) where n is an integer. Answer is B.</span>
Answer:
7/8
Step-by-step explanation:
Andrea recipe for cranberry relish is
1 3/4
= 7/4
He wants to use 1/2 of that amount
Therefore the amount of sugar he should use can be calculated as follows
= 7/4×1/2
= 7/8
Answer:
a,c,f
Step-by-step explanation:
, 1 gallon = 8 fluid oz so if its 2 u multiply 8 by 2
5 gallons and if its 8 oz each 8x5=40 oz
1 ,1/4 if 1 gallon is 8 we need to find what 1/4 of 8 is so u divide it and u get 2 and 8 plus 2 = 10
there might be more but i dont think there is
Your supposed to use sin= op over hypotenuse, coh= adjacent over hypotenuse , and tan= opposite over adjacent
4. For this you would use tan b/c the angle is opposite the degree and you have no hypotenuse. Equation will be tan30/1 = radical 6/x. And solve
3. Would be using sin with the equation
Sin45/1 = 7 radical 6/2 over x
It is letter C (look carefully)
