The answer is
A=1/2bh
So the base number times height number divided by two!!
Answer:
Step-by-step explanation:
Community gym
=> membership fee = $50
=> monthly fee = $55
=> First month = 105$
=> 50 + 55(x)
=> 50 + 55 (15)
=> 50 + 825
=> 875
Workout gym
=> membership fee = $200
=> monthly fee = $45
=> First month = 245$
=> 200 + 45(x)
=> 200 + 45(15)
=> 200 + 675
=> 875
On the 15th month, community gym and workout gym will both get the same amount of $875.
If <em>c</em> > 0, then <em>f(x</em> - <em>c)</em> is a shift of <em>f(x)</em> by <em>c</em> units to the right, and <em>f(x</em> + <em>c)</em> is a shift by <em>c</em> units to the left.
If <em>d</em> > 0, then <em>f(x)</em> - <em>d</em> is a shift by <em>d</em> units downward, and <em>f(x)</em> + <em>d</em> is a shift by <em>d</em> units upward.
Let <em>g(x)</em> = <em>x</em>. Then <em>f(x)</em> = <em>g(x</em> + <em>a)</em> - <em>b</em> = (<em>x</em> + <em>a</em>) - <em>b</em>. So to get <em>g(x)</em>, we translate <em>f(x)</em> to the left by <em>a</em> units, and down by <em>b</em> units.
Note that we can also interpret the translation as
• a shift upward of <em>a</em> - <em>b</em> units, since
(<em>x</em> + <em>a</em>) - <em>b</em> = <em>x</em> + (<em>a</em> - <em>b</em>)
• a shift <em>b</em> units to the right and <em>a</em> units upward, since
(<em>x</em> + <em>a</em>) - <em>b</em> = <em>x</em> + (<em>a</em> - <em>b</em>) = <em>x</em> + (- <em>b</em> + <em>a</em>) = (<em>x</em> - <em>b</em>) + <em>a</em>.

Step-by-step explanation:
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48
