James has decided to start saving for a cruise over the summer. His money is
currently in the local bank, modeled by the function s(x) = 102. He is able to do work
around the neighborhood to earn extra money and that function would be a(x) = 8
+ 2), where x is measured in hours. Explain to James how he can create a function
that combines the two, and describe any simplification that can be done.

Find the length of the third side. If necessary, round to the nearest tenth.
20
25
Answer:
15
Step-by-step explanation:
hypotenuse (h) = 25
perpendicular (p) = 20
base (b) = ?
we know by using Pythagoras theorem we get
b = √h² - p²
= √25² - 20²
= √225

Andrew drives through 5 intersections with stoplights on his way to work. He
records that he is stopped by a red light in 2 of the 5 intersections. If he uses
this as his general probability of getting stopped at a red light on his way to or
from work, how many times can he expect to be stopped at a red light over the
next 40 times he drives through an intersection on his route?
Andrew should expect to be stopped
times.
Answer:
16 times
Step-by-step explanation:
2 out of 5 is 40%
40 x 40% = 16
Answer: 16 times

Help please. It’s geometry and it asks to find the shaded region.
Answer: (a)
Step-by-step explanation:
Given
The diameter of the inner circle is [tex]d=14\ m[/tex]
thickness of the strip is [tex]t=2\ m[/tex]
So, the radius of inner circle is [tex]r=7\ m[/tex]
Radius of the outer circle [tex]R=7+2=9\ m[/tex]
Area of the shaded region is the difference of the area of outer circle and inner circle.
[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]
hence, option (a) is correct.

Write the equation in standard form for the circle with radius 4 centered at the origin
Answer:
common form to write the equation of a circle in is the center-radius form. The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.
Answer:
x² + y² = 16
Step-by-step explanation:
We need to write the standard equation of circle with , centre (0,0) and radius 4 unit . The Standard equation of the circle ⭕ is ,
=> ( x - h)² + (y -k)² = r²
=> ( x -0)² + (y-0)² = 4²
=> x² + y² = 16 .
• Hence the equation of the circle is x² + y² = 16.

Solve the equation 5x^2 - 2x - 9 = 0 using the quadratic formula. WILL MARK BRAINLIEST.
Answer:
[tex] x = \dfrac{1}{5} \pm \dfrac{\sqrt{46}}{5} [/tex]
Step-by-step explanation:
5x^2 - 2x - 9 = 0
a = 5; b = -2; c = -9
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-2) \pm \sqrt{(-2)^2 - 4(5)(-9)}}{2(5)} [/tex]
[tex] x = \dfrac{2 \pm \sqrt{4 + 180}}{10} [/tex]
[tex] x = \dfrac{2 \pm \sqrt{184}}{10} [/tex]
[tex] x = \dfrac{2 \pm \sqrt{4 \times 46}}{10} [/tex]
[tex] x = \dfrac{2 \pm 2\sqrt{46}}{10} [/tex]
[tex] x = \dfrac{1 \pm \sqrt{46}}{5} [/tex]
[tex] x = \dfrac{1}{5} \pm \dfrac{\sqrt{46}}{5} [/tex]

A card is drawn from a standard deck of cards. What is the probability
that a spade is drawn, then replaced, and a red card is drawn second?
A card is drawn from a standard deck of cards. What is the probability that a spade is drawn, NOT replaced, and another spade is drawn?
Answer:
With replacement
[tex]probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}[/tex]
[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement =[/tex][tex]\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}[/tex]
Without replacement
[tex]probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}[/tex]
[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}[/tex]

A softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher's hand at a velocity of 50 feet per second. If the softbal's acceleration is - 16
Ft/s2. This can be modeled with the equation (h=height, t=time) h(t)=16t^2 +50t+ 3
What is the time at which the softball would hit the ground it it were not hit or caught?
A.) .5 seconds
B.)3.12 seconds
c.) 3.18 seconds
D. ) 2.42
Answer:
Using their equation and the fact that the ball will fall 3 ft before reaching the ground:
3 = 16 t^2 + 50 t + 3 represents the given situation
16 t^2 + 50 t = t (16 t + 50) = 0
16 t + 50 = 0
t = 50 / 16 = 3.12 sec

Step-by-step explanation:
Cars are either race-car fast, slightly fast, or normal. It turns out that 10% of all cars are race-car fast, 40% are slightly fast, and 5% are normal. Of those that are race-car fast 70% are red, as are 45% of those that are slightly fast, and 30% of those that are normal. what is the probability that a randomly selected car is red given that it is normal?
Answer:
Probability = 37.5%
Step-by-step explanation:
Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%
Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%
Prob (Normal & Red Car) = 30% of 50% = 15%
Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) = 15% / 40% = 37.5%
