Jamie needs to determine the distance across a river. She selects a rock, R. on the opposite river bank. She finds a tree, T. on her side of the river such that RT is perpendicular to the river: Next, Jamie walks 50 yards down the river from the tree, T. to a spot, C. Using a compass that she made from two sticks, she measures TCR. She then walks from C in a direction that makes the same angle as ZTCR with the river bank on her side of the river. She keeps walking in that direction until she sees the tree and the rock in a straight line from her position. She marks this point B and then paces from B to T to measure the distance from point B to the tree. If BT turns out to be 75 yards, what is RT, the distance across the river? ​

Answer:

182 miles

driving distance is 196

Therefore, 5000 items can maximize the profit

The correct answer is an option (a)

The money that you make when you sell something for more than it cost you.

For given example,

profit is described by the equation :

[tex]P (x) = -x^2 + 10x -4[/tex]

We need to maximize the profit P(x)

[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]

since , x is the number of items made in thousand

Therefore, 5000 items can maximize the profit

The correct answer is an option (a)

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Check the solution by substituting x = [tex]\frac{\pi }{2}[/tex] into the left side of the equation

2sin²x - sinx - 1

= 2sin²([tex]\frac{\pi }{2}[/tex] ) - sin ([tex]\frac{\pi }{2}[/tex] ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

Answer:

320m

Step-by-step explanation:

let the two runners be A and B

with Va and Vb as their velocities

velocity=distance/time

Va=720/4*60

=3m/s

Vb=720/5*60

=2.4m/s

Let the 2 runners start from a common position X and meet at Y

so the 2 consecutive meetings happen at X and Y

so we have to find time of meeting at Y as we know that of X (which is t=0)

720=Va*t+Vb*t

t(5.4)=720

t=133.33 or t=720/5.4

therefore distance travelled by B =Vb*t

=2.4*720/5.4

=319.99m

=320m

Answer:

6cm

Step-by-step explanation:

Given data

Width= 4.6cm

Length= 9cm

Volume= 82.8cm^3

The expression for the volume is given as

V= lwh/3

82.8= 9*4.6*h/3

cross multiply

82.8*3= 9*4.6*h

248.4= 41.4h

h= 248.4/41.4

h= 6cm

Given that :

Mean = 14

Range = 7

Evaluating the options given :

A. $14, $14, $14, $14, $7, $7

For option A :

Mean = (14 + 14 + 14 + 14 + 7 + 7) = 70 / 6 = 11.66 (incorrect)

B. $14, $14, $14, $14, $14, $21

Mean = (14 + 14 + 14 + 14 + 14 + 21) = 91 / 6 = 15.17 (Incorrect)

C. $13, $13, $13, $15, $15, $15

Range = 15 - 13 = 2 ( Incorrect)

D. $13, $12, $15, $15, $11, $18

Range = (18 - 11) = 7

Mean = (13+12+(15*2)+11+18) / 6 = 84/6 = 14

Answer:

x = 101/20, y = 1/4

Step-by-step explanation:

Solve the following system:

{-y + 5 x = 25 | (equation 1)

3 y + 5 x - 1 = 25 | (equation 2)

Express the system in standard form:

{5 x - y = 25 | (equation 1)

5 x + 3 y = 26 | (equation 2)

Subtract equation 1 from equation 2:

{5 x - y = 25 | (equation 1)

0 x+4 y = 1 | (equation 2)

Divide equation 2 by 4:

{5 x - y = 25 | (equation 1)

0 x+y = 1/4 | (equation 2)

Add equation 2 to equation 1:

{5 x+0 y = 101/4 | (equation 1)

0 x+y = 1/4 | (equation 2)

Divide equation 1 by 5:

{x+0 y = 101/20 | (equation 1)

0 x+y = 1/4 | (equation 2)

Collect results:

Answer: {x = 101/20, y = 1/4

Answer:

The answer is 3

Step-by-step explanation:

It's just wisdom I mean think about it it

1.5 then 3

⭐ Initially, we have to find the reason why it was -1.5:

[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]

➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.

[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]

⌛ So, we will have to find what x is worth in this case:

[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]

[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]

→ Knowing this...

[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]

[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex]     [tex]\checkmark[/tex]

Answer:

H: 41

Step-by-step explanation:

upfront charge = 36

each cone costs .52

sell price 1.40

(sell price - cone cost) * number of cones - upfront cost =0 to find where break even is

-36+(1.40-.52)*x=0

-36+.88x=0

.88x=36

x=40.90

need to round up to break even to 41

Answer:

Option C 41 is correct answer.

Given:

Cost of rent of the equipment = 36 $

Cost on ingredients of each cone = 0.52 $

Selling price of each cone = 1.40

To find:

Number of cones(let = x) joel must sell in order to make a profit?

1.40x > 36+ 0.52x

subtracting 0.52 x from both the side,

1.40x - 0.52x > 36

0.88x > 36

dividing both side by 0.88,

x > 36/0.88

x> 40.909090....~ 41

Option C 41 is correct answer.

Answer: Coupon B gives the lower price

The price of coupon B is  3.75 dollars   less than the price of coupon A.

======================================================

Explanation:

15% off means she saves 15% of the original price.

15% of 95 = 0.15*95 = 14.25

Rachel saves $14.25 if she goes with coupon A.

We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).

If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars

Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.
