Answer:
The ball takes 5 seconds to hit the ground
Step-by-step explanation:
The equation to model the height of a golf ball in time t is:
[tex]h(t)=80t-16t^2[/tex]
There are two moments when the height is zero: At launch time and when it hits the ground. To find the last time, we equate:
[tex]80t-16t^2=0[/tex]
Factoring out t:
[tex]t(80-16t)=0[/tex]
It gives us two solutions:
t=0
[tex]80-16t=0[/tex]
Solving:
[tex]-16t=-80[/tex]
[tex]t=-80/(-16)=5[/tex]
t = 5 sec
Thus, the ball takes 5 seconds to hit the ground

X=9.5
So x is less than 10
Answer:
Step-by-step explanation:
Because of the plus 5. You know for a fact that 10 times 10 is 100 but you need something less than 10 for the equation to be true since you're adding onto the answer to get 100

Answer:
B. 6,8,10
Step-by-step explanation:
to find a right triangle the equation: a^2 + b^2 = c^2, so just plug each number in to see.
6^2 + 8^2 = !0^2
36 + 64 = 100
100 = 100
Personally i knew almost immediately because 3,4,5 are the most common right triangles example and 6,8,10 are just a x2 of them so yea.

find angle prq
please solve this
Answer:
∠ PRQ = 55°
Step-by-step explanation:
The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus
∠ PQR = 0.5 × 110° = 55°

HELP!! It’s due today
Answer:
B. 1 horse per 20 pounds hay
C. YEs, an equation that can represent this is y=20x where x is the number of horses and y is the hay. Because i can make an equation that works for any value in this table, it is proportional.
Step-by-step explanation:
Answer: a) 1 2 3 4 5 6 7
20 40 60 80 100 120 140
b) 20 pounds of hay/horse
c) Yes. An increase in 1 horse results to an equivalent increase of 20 pounds of hay.

What inequality is shown in the graph below?
Answer:
x > 2
Step-by-step explanation:
From the graph attached,
Given dotted line represents x = 2.
Since, given line is a dotted line, inequality represented by the dotted line will have the sign of greater than or less than (< or >) only.
Since, shaded region is on the right side of the dotted line shaded region will be represented by the inequality x > 2

6 − 4v = 3 − v
Answer: = 1
Step-by-step explanation: 6−4v=3−v
Step 1: Simplify both sides of the equation.
6−4v=3−v
6+−4v=3+−v
−4v+6=−v+3
Step 2: Add v to both sides.
−4v+6+v=−v+3+v
−3v+6=3
Step 3: Subtract 6 from both sides.
−3v+6−6=3−6
−3v=−3
Step 4: Divide both sides by -3.
−3v
−3
=
−3
−3
v=1
Answer:
v=1
Answer:
V=1
Step-by-step explanation:
6 - 4v = 3 - v
move the varible
6 - 4v + v = 3
collect like terms
-3v = 3 - 6
divide both sides by -3
V = 1
Samantha has $300 for guitar lessons to learn her favorite song. Mrs. Jones charges $80 per lesson and requires three lessons to teach Samantha the song. Mr. Beliz charges $62 per lesson and requires four lessons to teach Samantha the song. Use integers to represent what each teacher charges. Which is the better deal for Samantha?
Answer:
Mrs. Jones has the better deal
Step-by-step explanation:
Samantha has $300
Mrs. Jones charges $80 per lesson and she requires three so we do 80* 3 (the lessons) which equals 240
Mrs. Beliz charges $62 per lesson and requires 4 lessons so we do 62*4 (the lessons) which equals 248
240<240 (so Mrs. Jones has the better deal, she wants less money)
Answer:
Mrs. Jones
