Answer:
60
Step-by-step explanation:
x = (1/2)(172 - 52)
x = (1/2)(120)
x = 60
To change a fraction into a decimal, divide the numerator by denominator. This gets you a decimal. Example.
4/25 Oh OK! 4 divided by 25 equals.... 0.16! GG

Answer: 30%
Step-by-step explanation:
Total number of people involved in the tournament= 50
Number of people chosen to play rugby= 35
Number of people chosen to play football= 15
To get the percentage of people that are chosen to play football, we divide the number of people chosen to play football by the total number of people chosen for the tournament and then multiply the answer by 100. This will be:
= 15/50 × 100
= 0.3 × 100
= 30%
The percentage of people chosen to play football is 30%.
Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10
Step-by-step explanation:
The height of the baseball is 6 feet at the moment the player begins to leap. Then the correct option is D.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The first equation in the system models the height in feet, h, of a falling baseball as a function of time, t. the second equation models the height in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.
h(t) = 35 - 16t²
h(t) = 6 + 18t + 16t²
At t = 0, Then we have
h(0) = 35 - 16(0)²
h(0) = 35
And
h(0) = 6 + 18(0) + 16(0)²
h(0) = 6
The height of the baseball is 6 feet at the moment the player begins to leap.
