A bird releases waste from a height of
400 feet. If the equation for height as a
function of time is
h(t) = - 16t^2 + initial height where t is
time in seconds and h(t) is height in
feet, how many seconds will it take for
the waste to hit the ground?

Answers

Answer 1

Answer:

5secs

Step-by-step explanation:

Given the equation of the height expressed ad;

h(t) = - 16t^2 + initial height

Given that initial height = 400feet

h(t) = - 16t^2 + 400

The waste will hit the ground at when h(t) = 0

substitute

0 =  - 16t^2 + 400

16t^2 = 400

t² = 400/16

t² = 25

t = √25

t = 5secs

Hence it will take the easte 5secs to hit the ground

Step-by-step explanation:

If you would recall one of the laws of exponents, when dividing powers of the same base you subtract their exponents. So for this expression:

6⁷ ÷ 6⁵ = 6^(7-5) = 6² =36

A dealer purchased 250 bulbs for Rs10 each. However, 12 bulbs got fused which he had to throw away. He sold the remaining bulbs at Rs 12 each. Find the gain or loss per cent in the dealing.​

Answers

Answer:

CP of 1bulb =Rs10

CP of 250bulbs=Rs2500

Number of defective bulbs 12

remaining bulbs =250−12=238

SP of 1bulb =Rs12

SP of 238bulbs=Rs2856

Answers

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

See below for answers and explanations to the first 5 problems

Step-by-step explanation:

Problem 1:

cos(x) = 2/3

sec(x) = ?

sec(x) = 1/cos(x)

sec(x) = 1/(2/3)

sec(x) = 3/2

Problem 2:

sinβ = -5/6

cscβ = ?

cscβ = 1/sinβ

cscβ = 1/(-5/6)

cscβ = -6/5

Problem 3:

secφ = 2

tanφ = √3

sinφ = ?

secφ = 1/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ(1/secφ)

√3 = sinφ(1/2)

2√3 = sinφ

Problem 4:

secθ = 8

tanθ = 3√7

cscθ = ?

secθ = 1/cosθ

tanθ = sinθ/cosθ

cscθ = 1/sinθ

tanθ = sinθ/cosθ

tanθ = sinθ(1/cosθ)

3√7 = sinθsecθ

3√7 = sinθ(8)

(3√7)/8 = sinθ

cscθ = 1/sinθ

cscθ = 1/((3√7)/8)

cscθ = 8/(3√7)

cscθ = (8√7)/21

Problem 5:

sinθ = 2/√5

cosθ = 1/√5

tanθ = ?

tanθ = sinθ/cosθ

tanθ = (2/√5)/(1/√5)

tanθ = (2/√5)(√5)

tanθ = 2
