Granny is 56 years old, and her granddaughter is 14. In how many years from now will the grandma be twice as old as the granddaughter?

a) 28
b) 23
c) 10
d) 25

HELPP​

Answers

Answer 1
Set up the problem as an equation where X is years: 14+X = (56+X)/2 Solve for X 14+X = 28 + 0.5*(X) subtract 14 from both sides: X = 14 + 0.5*(X) subtract 0.5*(X) from both sides: 0.5*(X) = 14 Solve for X by dividing both sides by 0.5: X = 28

So the answer is a) 28

Find the height of a tree of angle of elevation of its top changes from 25 degree to 50 degree as the observer advance 15m towards its base

please help me fast​

Answers

Answer:

  11.5 m

Step-by-step explanation:

The problem can be solved using a trig relation that relates the side opposite the angle to the side adjacent to the angle. That relation is ...

  Tan = Opposite/Adjacent

The lengths of the adjacent sides of the triangle can be found by rearranging this formula:

  Adjacent = Opposite/Tan

__

The "opposite" side of the triangle is the height of the tree, which we can represent using h. The problem statement tells us of a relation between adjacent side lengths and angles:

  h/tan(25°) -h/tan(50°) = 15 . . . . . moving 15 meters changes the angle

  h(1/tan(25°) -1/tan(50°)) = 15

  h = 15·tan(25°)·tan(50°)/(tan(50°) -tan(25°)) = 15(0.55572/0.72545)

  h ≈ 11.4907 . . . . meters

The height of the tree is about 11.5 meters.

Answers

The amount needed such that when it comes time for retirement, an individual can make semiannual withdrawals in the amount of $15,265 for 35 years is $225093.358.

The total amount to be withdrawn in a year = 15265*2 = $30530

The total amount to be withdrawn in 35 years =$1068550

What is the compound interest?

Compound interest is interest on interest along with interest on the principle.

Annual Rate of interest = 4.5%

Semi-annual rate of interest r=2.25%

Amount A= $1068550

[tex]1068550 =P(1+\frac{2.25}{100})^70[/tex]

[tex]P = $225093.358[/tex]

Therefore, the amount needed such that when it comes time for retirement, an individual can make semiannual withdrawals in the amount of $15,265 for 35 years is $225093.358.

Sketch the graph of y=x^2-4x+3

Answers

Answer:

see attached graph

Step-by-step explanation:

Given equation:  [tex]y=x^2-4x+3[/tex]

Standard form of a quadratic equation: [tex]y=ax^2+bx+c[/tex]

where [tex]c[/tex] is the y-intercept

If [tex]a > 0[/tex] then the parabola opens upwards.

If [tex]a < 0[/tex] then the parabola opens downwards.

Therefore, the y-intercept of the graph is (0, 3)

To find the x-intercepts, factor the equation:

       [tex]y=x^2-4x+3[/tex]

[tex]\implies y=x^2-x-3x+3[/tex]

[tex]\implies y=x(x-1)-3(x-1)[/tex]

[tex]\implies y=(x-3)(x-1)[/tex]

Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)

To determine the vertex, differentiate the equation:

[tex]\implies \dfrac{dy}{dx}=2x-4[/tex]

Set to zero and solve for x:

[tex]2x-4=0 \implies x=2[/tex]

Substitute [tex]x=2[/tex] into the original equation and solve for y:

[tex]\implies y=(2)^2-4(2)+3=-1[/tex]

Therefore, the vertex (or turning point) is at (2, -1)

Based on a poll of 1000 residents, a newspaper article claims that 62% of the residents in town favor the development of a recreational park on the west side of town. A community action group interested in preserving the environment claims that 45% of the town’s residents favor the development of a recreational park. To determine whether the sample supports the population proportion, a simulation of 100 trials is run, each
with a sample of 200, using the point estimate of the population. The minimum sample proportion from the simulation is 0.46 and the maximum sample proportion is 0.76.

(a) What is the point estimate of the population? Answer is $0.62

(b) The margin of error of the population proportion is found using an estimate of the standard deviation. What is the interval estimate of the true population proportion?

(c) The margin of error of the population proportion is found using half the range. What is the interval estimate of the true population proportion?

(d) Is the community action group’s claim likely based on either interval estimate of the true population proportion? Explain.

Answers

The probability computed shows that the point estimate of the population is 6.2%.

How to calculate the probability?

a. The point estimate of the population will be calculated thus:

= 62% = 62/100 = 0.62

b. The margin of error of the population will be:

= z value × [✓0.62 × ✓0.38 / ✓200]

= 1.96 × (0.78 × 0.61 / 14.14)

= 0.0672

Therefore, the interval estimate is 6.72%.

c. The margin of error of the population proportion is found using half the range will be:

= [0.76 - 0.46] /2

= 0.30/2

= 0.15

d.  The community action group’s claim is likely based on either interval estimate of the true population proportion since the confidence interval value is greater than 0.45.
