Answer:
D
Step-by-step explanation:
If the least it can be is 12, that means that with will have to be equal to 12
so mark out a and b
It also said the <u>least</u>, this means it can not be less than it.
Put these two together and you get D) k is greater than or equal to 12
Answer:
Step-by-step explanation:
y = x^2 + 4
x = 11 Put this value in wherever you see an x on the right.
y = 11^2 + 4
11^2 = 11 * 11 = 121
y = 121 + 4
y = 125

Answer:
2/3 feet.
Step-by-step explanation:
The formula for finding the area of a triangle is A = (B x H)/2. Or, area is equal to base times height, all divided by two. In your case, we don't know the base. If we substitute in values, we get 2/5 = (B x 6/5)/2.
Next, we have to multiply both sides by two, to cancel the "/2." That results in 4/5 = B x 6/5. Then, to isolate the variable, we have to divide both sides by 6/5. 4/5 ÷ 6/5 is 4/5 x 5/6. The fives cancel out, and we are left with 4/6.
Finally, we simplify! 4/6 simplifies to 2/3.
I=10^(1-0.13x)
When I=4.2, then:
4.2=10^(1-0.13x)
ln 4.2=ln(10^(1-0.13x))
ln 4.2=(1-0.13x)ln (10)
1-0.13x=ln 4.2 / ln 10
-0.13 x=(ln 4.2 /ln 10)-1
x=[(ln 4.2/ ln 10)-1] /(-0.13)
x=-0.37675/(-0.13)
x=2.898...≈2.9
