A basketball is thrown upward from a height of 1.8 m at a velocity of 12 m/s. How long until it reaches the ground?
Recall: h(t)=-4.9t^2-v_0 t+h_0, where v_0 is initial velocity and h_0 is initial height.
can anyone help?!
Answer:
0.14secs
Step-by-step explanation:
Given the equation that models the height expressed as;
h(t)=-4.9t^2-v_0 t+h_0
Given v0 = 12m/s
h0 = 1.8m
The equation becomes
h(t)=-4.9t^2-12t+1.8
The height of the ball on the ground level is zero
Substituting into the equation
0 = -4.9t^2-12t+1.8
Multiply through by -10
49t²+120t-18 = 0
Factorize and get t:
t = -120±√120²-4(49)(-18)/2(49)
t = -120±√14400+ 3528/98
t = -120±√17928/98
t = -120±133.89/98
t = 13.89/98
t = 0.14secs
Hence it takes 0.14secs until it reaches the ground

Answer:
Choice D: not possible
Step-by-step explanation:
The reason why it's not possible is that when you try to make an equation it never comes out correct. You could also try plugging in the numbers then figure it out that way. It's not possible either way you do it.

Ann has to make payments twice a year on her health insurance. If each payment is $2,316, how much money should she budget for health insurance each month? Round to the nearest dollar. A. $579 B. $386 C. $1,158 D. $193
Answer:
$386
Step-by-step explanation:
If Ann has to pay $2316 twice a year
(every 6 months), then, we calculate
$2316/6 = $386 every month.
Hence, Ann's budget for health
insurance each month is $386.

Attend to precision. Suppose that ∠1 and ∠2 are same-side interior angles formed by two parallel lines cut by a transversal, and that m∠1=7x-4 and m∠2=20x-5.
a.What is the value of x?
b.What is m∠1?
c.What is m∠2?
d.Explain how you found your answers.
9514 1404 393
Answer:
a) x = 7
b) m∠1 = 45°
c) m∠2 = 135°
Step-by-step explanation:
a) Same-side interior angles are supplementary, so we have ...
∠1 +∠2 = 180
(7x -4) +(20x -5) = 180
27x = 189
x = 7
__
b) The measures of the angles can be found by substituting the value of x into the express for the angle measure.
m∠1 = 7x -4 = 7(7) -4 = 45
m∠1 = 45°
__
c) Angle 2 is the supplement of angle 1, so ...
m∠2 = 180° -45°
m∠2 = 135°
__
d) We used the relationship of angles at a transversal and the properties of equality.

Solve for x using the
distributive property.
3(x + 4) = 6
Hello!
[tex]\large\boxed{x = -2}[/tex]
3(x + 4) = 6
Distribute the terms inside of the parenthesis with the coefficient outside:
3(x) + 3(4) = 6
Simplify:
3x + 12 = 6
Subtract 12 from both sides:
3x + 12 - 12 = 6 - 12
3x = -6
Divide both sides by 3:
3x/3 = -6/3
x = -2

WILL MARK BRAINLY! The population of a particular city is given by the function P(t) = 82,100(1.02), where t is the time in years and P(t) is the population after t years. What is the current population, the percentage growth rate, and the population size (rounded to the nearest whole person) after 15 years?
Hint: Percentage Growth Rate = r × 100 in A= A0(1 + r)^t
○ 82,100, 2% semiannually, 110,658
○ 82,100, 10.2% annually, 352,425
○ 82,100, 2% annually, 110,496
○ 82,100, 20% semiannually, 985,200
Answer:
P(t) = 82,100(1.02)^t
1.t is the time in years
2.P(t) is the population after t years
3. 100%=1 102-100=2% so the interest rate is 2 %

how to solve this problem
Answer:
a = 4
b = -2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Equality PropertiesSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
a + 4b = -4
a + 10b = -16
Step 2: Rewrite Systems
a + 4b = -4
Subtract 4b on both sides: a = -4 - 4bStep 3: Redefine Systems
a = -4 - 4b
a + 10b = -16
Step 4: Solve for b
Substitution
Substitute in a: -4 - 4b + 10b = -16Combine like terms: -4 + 6b = -16Isolate b term: 6b = -12Isolate b: b = -2Step 5: Solve for a
Define equation: a + 4b = -4Substitute in b: a + 4(-2) = -4Multiply: a - 8 = -4Isolate a: a = 4find the values if a and b such that x squared + 2x -7 = (x+a) squared + b
Given:
[tex]x^2+2x-7=(x+a)^2+b[/tex]
To find:
The values of a and b.
Solution:
We have,
[tex]x^2+2x-7=(x+a)^2+b[/tex]
It can be written as
[tex](x^2+2x)-7=(x+a)^2+b[/tex]
Add and subtract square of half of coefficient of x in the parenthesis.
[tex](x^2+2x+(\dfrac{2}{2})^2-(\dfrac{2}{2})^2)-7=(x+a)^2+b[/tex]
[tex](x^2+2x+1^2)-1-7=(x+a)^2+b[/tex]
[tex](x+1)^2-8=(x+a)^2+b[/tex] [tex][\because (x+y)^2=x^2+2xy+y^2][/tex]
[tex](x+1)^2+(-8)=(x+a)^2+b[/tex]
On comparing both sides, we get
[tex]a=1[/tex]
[tex]b=-8[/tex]
Therefore, the value of a is 1 and the value of b is -8.

The partially filled contingency table gives the frequencies of the data on age (in years) and sex from the residents of a retirement home. 60-69 70-79 Over 79 Total Male 10 2 5 Female 10 9 4 Total
What is the relative frequency for males in the age group 60-69?
a. 1/2
b. 13/40
c. 1/4
d. 9/40
Please select the best answer from the choices provided
Answer:
c. 1/4
Step-by-step explanation:
got right edge2021
The relative frequency for males in the age group 60-69 is 1/2. So, option A is the correct one.
Given that,
Total number of residents in the retirement home who are in the age group 60-69 = 10 + 10 = 20
Number of males who are in the age group 60-69 = 10
The formula to find the relative frequency is,
Relative frequency = Number of counts in the subgroup / Total counts
Substituting,
Relative frequency = 10/20 = 1/2

Researchers compare the body composition of cattle feeding on a grain diet with that of cattle feeding on a grass diet. This method of gathering data is classified as
a census.
a sample survey.
an experiment.
an observational study.
d is ur answer⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Answer:
The answer is D. An observational study
Step-by-step explanation:
The researchers are observing how different diets in the cattle affects their body composition. They are not counting a population or anything so it is not a census. It is not a sample survey because they aren't asking cows and it is not an experiment because they are not changing or testing anything. They are just viewing meaning it is an observational study.
