Answer:
A.
Step-by-step explanation:
in A. your q is 3 so: a1=1 a2= a1*q=3 a3=a2*q=9 and so on.
i C. its almost the right answer too,but notice that a1 is 0. so 0*2 is still 0 so though it looks almost perfect the first number ruins it
[tex] - 9 \times 4 = [/tex]

A child throws a ball upward with an initial velocity of 15 ft/s from a height of 2 feet. Let ℎ = 0 and solve. If no one catches the ball, how long will it be in the air? Round to the nearest hundredth. ℎ = −16 2 + v + where v is the initial upward velocity with starting height
Answer:
1.056 seconds
Step-by-step explanation:
Solution:-
- When a ball is thrown vertically in air from a height of "so" from the ground at a velocity of " vo " it follows a parabolic trajectory. The ball undergoes its upward motion against gravity. Hence, it has negative acceleration of a = -g = -32 ft/s^2.
- When the balls reaches its maximum height in air, it starts its downward journey under the complete influence of gravity; hence, it accelerates with a = +g = 32 ft/s^2.
- The entire trajectory of the ball is governed by the constant acceleration "a" due to gravity and neglecting any other effects on the ball i.e air resistance.
- There are three kinematic equation of motion valid for any particle undergoing independent one dimensional motion with constant acceleration.
- For vertical trajectory the displacement "h" from the ground is given by the second kinematic equation of motion:
h - so = vo*t + 0.5*a*t^2
h = vo*t + 0.5*a*t^2 + so
Where the parameters are given as:
so = 2 feet
vo = 15 ft/s
a = - 32 ft/s^2
Therefore we have:
h = 15*t + 0.5*(-32)*t^2 + 2
h = -16t^2 + 15t + 2
- To determine the amount of time the ball is in air the displacement is given by the distance from the ground. The journey starts when the ball is thrown from height "so" and ends when it strikes the ground; hence, at h = 0 ft.
0 = -16t^2 + 15t + 2
0 = 16t^2 -15t - 2
- Use the quadratic formula to solve for time "t":
[tex]t = \frac{-b+/-\sqrt{b^2 - 4*a*c} }{2a} \\\\at^2 + bt + c = 0[/tex]
- Plug in the respective constants:
[tex]t = \frac{15+/-\sqrt{15^2 - 4*16*-2} }{32} \\\\ t = \frac{15+/-18.78829 }{32} \\\\t = 1.056 s[/tex]
- The total time for ball in air would be 1.056 seconds. ( Neglect the negative value of time )

Find the amount of money in an account after 4 years if $1800 is deposited at 5% annual interest compounded quarterly.
Answer:
$2195.80
Step-by-step explanation:
For a initial principal, P compounded with period k over n years at an annual interest rate, r, the amount (A(n)) at the end of n years is determined using the function:
[tex]A(n)=P(1+\frac{r}{k})^{nk}[/tex]
In the given case:
P=$1800
n=4 years
r=5%=0.05
Since it is compounded quarterly, Period, k=4
Therefore, the amount of money in the account after 4 years is:
[tex]A(n)=1800(1+\frac{0.05}{4})^{4*4}\\=1800(1+0.0125)^{16}\\=1800(1.0125)^{16}\\=\$2195.80[/tex]
After 4 years, there will be $2195.80 in the account.
Ann and tom want to establish a fund for their grandson's college education. What lump sum deposit at a 12.7% annual interest rate compounded annually interest rate in order to have 20,000 in the fund at the end of 15 years
Answer:
2,683.34
Step-by-step explanation:
A=p(1+r/n)^nt
P=A/(1+r/n)^nt
A=20,000
r=12.7%=0.127
t=15
n=12
P=?
P=20,000/(1+/0.127/12)^12.7*15
=20,000/(1+0.0106)^190.5
=20,000/(1.0106)^190.5
=20,000/7.4534
P=2,683.3391
Approximately
P=2,683.34
can you please explain ME how to solve identity of algebra homework
Step-by-step explanation:
"identity" means an operation that does nothing.
For adding numbers, adding 0 changes nothing, so 0 is the identity for addition.
For multiplication, multiplying by 1 changes nothing, so 1 is the identity for multiplication.

James, Priya, and Siobhan work in a grocery Store. James makes $9.00 per hour. Priya makes 40% more than James, and Siobhan makes 15% less that Priya. How much does Siobhan make per hour?
Answer:
* Siobhan's profit at the grocery store ⇒ $ 10.8 *
Step-by-step explanation:
See below;
Priya's 40% profit in the grocery store ⇒ 40/100 * 9 = 2/5 * 9 = 18/5 ⇒ $ 3.6,
Priya's profit at the grocery store ⇒ 9 + 3.6 ⇒ $ 12.6,
Siobhan's 15% of Priya's profit from the store ⇒ 15/100 * 12.6 = $ 1.8
Siobhan's profit at the grocery store ⇒ 12.6 - 1.8 = $ 10.8
* Siobhan's profit at the grocery store ⇒ $ 10.8 *

Answer: 17.2
Step-by-step explanation:
You must use the law of sines, which says that sinA/a = sinB/b = sinC/c, where the side is the side across from the angle.
the length of side a = 16m, and the angle A = 25.
the length of side b = x, and the angle B = 27
1. sinA/a = sinB/b
2. sin25/16 = sin27/x
3. x(sin25)/16 = sin27
4. x = 16sin27/sin25
5. x = 17.2

Answer:
D
Step-by-step explanation:
The equation of the parabola is of the form
y = ax² + c ( where c is the y- intercept )
Here c < 0
Since the parabola has a maximum value and opens down then a < 0
Thus the only equation that could represent this parabola is
y = - x² - 3 → D
Mattie is making a collar for her dog. She needs to buy some chain, clasp, and a name tag. She wants the chain to be 40 cm long. On meter of chain costs $9.75. The clasp is $1.29 and the name tag is $3.43. How much will it cost to make the collar? Estimate to check if your answer is reasonable.
Answer: $8.62
Step-by-step explanation:
Mattie wants to make a collar for her dog. She needs to buy some chain, clasp, and a name tag. Mattie wants the chain to be 40 cm long. On meter of chain costs $9.75, the clasp is $1.29 and name tag is $3.43.
Since 100 centimeters = 1 metre. Mattie needs 40cm and 1 meter of chain costs $9.75, cost of the chain Mattie needs will be:
= 40/100 × 9.75
= 2/5 × 9.75
= $3.90
Chain(40cm) = $3.90
Clasp = $1.29
Name tag = $3.43.
Cost to make collar will be:
= $3.90 + $1.29 + $3.43
= $8.62

Solve the equation: 1/3 x - 4 = 28
Answer:
x = 96
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 4 to both sides:
(1/3)x - 4 (+4) = 28 (+4)
(1/3)x = 28 + 4
(1/3)x = 32
Next, multiply 3 to both sides:
(3)(1/3)x = (32)(3)
x = 32 * 3
x = 96
x = 96 is your answer.
~
Answer:
96=x
Step-by-step explanation:
Add 4 to each side
1/3x= 32
multiply 3 on each side to cancel out the fraction
x=96

Zain bought ice cream and sherbet at the grocery store and is placing the containers in the freezer. The container of ice cream was sold in a 10" × 14" × 12" container, and the sherbet was sold in an 11" × 18" × 9" container. How much less space does the container of ice cream occupy than the container of sherbet? *
Answer:
102 in^3.
Step-by-step explanation:
Volume of the ice cream container = 10*14*12 = 1680 in^3.
Volume of the sherbet container = 11*18^9 = 1782 in^3.
So the answer is 1782 - 1680
= 102 in^3.

b) Solve x + 5x + 6 = 0
Answer:
Step-by-step explanation:
The solutions are
x=2,x=3
Explanation:
x2−5x+6=0
Here we can first factorise the expression and then find the solution:
Factorising by splitting middle term
x2−2x−3x+6=0x(x−2)−3(x−2)=0(x−2)(x−3)=0
Equating the two factors with zero to obtain solutions:
x−2=0,x=2x−3=0,x=3
Answer:
x + 5x + 6
x + 3x + 2x +6
x(1 + 3) + 2(x + 3)
(x + 3) (x+2) = 0
x = -3 (or) x = -2

Find the area of the shaded region. Round your answer to the nearest tenth. Put the units on the answer for full credit
Answer:
Area of Shaded Region: 189 square centimeters
Step-by-step explanation:
~ To find the area of the shaded region, let us calculate the area of the rectangle added to the area of the two triangles, or the area of the whole triangle created from the two smaller triangles ~
1. Given dimensions of 15 by 9 centimeters, the area of the rectangle would be ⇒ 15 cm * 9 cm = 135 cm^2
2. It would be simpler if we were to consider the area of the larger triangle. The height in this case, by the Partition Postulate, would be 27 cm - 15 cm ⇒ 12 centimeters. Now provided that the shape with dimensions 15 cm by 9 cm is a rectangle, opposite sides are ≅, and thus ⇒ the base of this large triangle is 9 cm. That being said we can calculate the area of the triangle by ⇒ 1/2 * base * altitude ⇒ 1/2 * 9 cm * 12 cm ⇒ 6 cm * 9 cm ⇒ 54 cm^2
3. The area of the shaded region is thus 135 cm^2 + 54 cm^2 ⇒ 189 cm^2
Area of Shaded Region: 189 square centimeters

The value of x from the given parallelogram ABCD is 7. Therefore, option B is the correct answer.
In the given figure, AD=5x+3 and BC=38.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
In the parallelogram ABCD, AD=BC
So, 5x+3=38
⇒ 5x=35
⇒ x=7
The value of x from the given parallelogram ABCD is 7. Therefore, option B is the correct answer.
