Unit Test / 16 of 25
Rzqust [24]

Answer:

30

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

6+n\geq \frac{80}{100}\times (15+n)

\Rightarrow 30+5n\geq 60+4n

\Rightarrow n\geq 30.

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

Which two points lie on the circumference of this circle? A. (1.3,0.5) B. (2.5,1.5) C. (3.4, -0.2) D. (3.9,0.7) E. (6.0,-2.0)
liq [111]

Step-by-step explanation:

(x-2)²+(y+5)²=25

option C (3.4,-0.2)

LHS= (3.4-2)²+(-0.2+5)²

= (1.4)²+(4.8)²

= 1.96+23.04

= 25

option E(6,-2)

LHS= (6-2)²+(-2+5)² = 4²+(-3)² = 16+9 = 25

babunello [35]

Answer:

y = - 2x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = \frac{-4-0}{0-(-2)} = \frac{-4}{0+2} = \frac{-4}{2} = - 2

the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4

y = - 2x - 4 ← equation of line
