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
What is the right answer?
Answer:
The answer would be: B- X
Step-by-step explanation:
It would be X because you just count how many feeders and put it over the amount of birds.
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.
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
profit=Total SP-CP=2856−2500=Rs356

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

Answer:
y ≤ x
Step-by-step explanation:
The sloping line is solid, which means that any point on this line, or below it, is a solution of the given inequality.
Thus, the solution is y ≤ x, represented by the blue shaded area and the line y = x.

Answer:
C should be correct and super sorry if its wrong
Step-by-step explanation:
Help please !!!!!!!!!!!
Answer:
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
SOLVE FOR X PLEASEEE HELP
Answer:
2.2857
Step-by-step explanation:
To solve this I'm going to find Angle A
I have the adjacent and opposite side so using TOA is easiest
let a= angle
tan(a)=4/7
a=29.74488
Now that we have the angle A we can only look at triangle ABC
To solve for x we use TOA again
tan(29.74488)=x/4
4tan(29.74488)=x
x=2.2857
Answer:
2.28
Step-by-step explanation:
∆ABC~∆ADE
So, x/4=4/7
7x=16
x=16/7
x=2.28
