Answer:
we have
Cos (a+b)=Cos aCosb-SinaSinb
for
Cos (a+a)=Cos aCosa-SinaSina=<u>Cos²a-Sin²a</u>
is a required answer.
No. 500÷111=4.50 meaning that it can't be simplified
Hello!
Convert the percentages to decimals by dividing them by 100, and then multiply them by the amount of boys and girls.
53 ÷ 100 = 0.53 as a decimal
0.53 × 300 girls = 159
This means that 159 of the 300 girls play sports.
Repeat this to calculate how many boys play sports.
39 ÷ 100 = 0.39
0.39 × 500 = 195
This means that 195 out of the 500 boys play sports.
Final Answer:
More boys play sports than girls.
Answer:
12
Step-by-step explanation:
For our problem since we only in 10 am:
I'm going to let x=4 represent the time 10:04 am
which means I'm going to let x=17 represent 10:17am.
So when x=4, y=23 miles and when x=17,y=179 miles.
You have two points.
You can use the formula 
.
Or just line the points up vertically and subtract them vertically, then put 2nd difference over first difference. Like this:
( 17 , 179)
-( 4 , 23)
-----------------------
13 156
So the slope is 156/13=12 miles/hour.
Answer:
A. g(x)=x^2+5x+2
Step-by-step explanation:
f(x) = x^2 + 5x - 1 Shift 3 units to the left. k=3
g(x)=x^2+5x-1+3=x^2+5x+2
g(x)=x^2+5x+2
Hope this helps!
If not, I am sorry.
