Answer:
68.7
Step-by-step explanation:
We need only estimate (approximate) the value of f(x) at x = 5:
f(x)=6.87(2.5)(x – 1) → f(5)=6.87(2.5)(5 – 1).
Note that 2.5(4) = 10, so now we have (exactly) f(5)=6.87(10), which, in turn, is
equal to 68.7.
Answer:
prime factors are factors of a number that are prime numbers, (meaning they can only be divided by 1 and itself), while odd numbers are numbers that are odd..
all odd numbers have prime factors but not all prime factors are odd numbers
Answer:
X=7
Step-by-step explanation:
STEP 1: Simplify both sides of the equation
7x + -10 + 2x =39 + 2x
(7x + 2x) + (-10) = 2x + 39 (combine like terms)
9x -10 = 2x + 39
step 2: Subtract 2x from both sides
9x -10 - 2x = 2x + 39 - 2x
7x - 10 =39
Step 3: Add 10 to both sides.
7x - 10 + 10 = 39 + 10
7x = 49
Step 4: Divide both sides by 7.
7x/ 7 = 49/7 <u> x=7</u>
<u>hope this helps!!</u>
Square needs to have all equal sides and length and width are the same.
So sqrt the area.
sqrt 121 = 11
11 feet is the length of one side, square has 4.
So
11 * 4 = 44
The perimeter of a square (whose area is 121 feet) is 44 feet.
Find the total amount in grams.
1 kg = 1000 g
1.4 * 1000 = 1400
So she bought a total of 1400 grams.
Add up the grams she used:
400 + 250 = 650
Subtract it from the total:
1400 - 650 = 750
So 750 grams of sequence were left.
