hi im just gonna answer for the 20 points

Answer:

2.5 hours

you would take your total miles 95 and divide it by 38 ans it gives you 2.5

Answer:

2.5 hours aka 2 hours and 30 minutes  

Step-by-step explanation:

use unit analysis:

[tex]95 miles * \frac{1 hour}{38 miles}=\frac{95}{38}=2.5 hours[/tex]

when you set up an equation like this, make sure you set it up so you end up with the unit you want. your question asked how long, whihc means our answer was going to be a unit of time, in this situation: hours.

so the given distance was 95, multiply that by the rate of change and make sure miles is in the denominator so that the "miles" get cancelled out and you're left with the unit of hours.

Answer:2√2 + 3√8 = 2√2 + 6√2 = 8√2 , because we simplified √8 = √(4 * 2) ... Now, when you place 1/2 instead of m you'll get nothing else but a square root:.

Answer:

√8+√2 =3.2^½

Step-by-step explanation:

√8 = √4*2 = 2√2

√8+√2 = 2√2+√2 = 3√2

√2 = 2^½

√8 +√2 = 3.2^½

The equivalent expression to[tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]  is  [tex]\frac{1}{\sqrt{2(cosx+1)} }[/tex]. option A is correct.

Equivalent expression to[tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]  determine.

Evaluation is defined as finding a solutions to mathematical problems.

Here, we have [tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]
[tex]=\frac{sin(x/2)tan(x/2)}{1-cos(x)}\\ =\frac{sin(x/2)\frac{sin(x/2)}{cos(x/2)} }{2sin^2(x/2)} \\= \frac{sin(x/2)^2}{2cos(x/2)sin^2(x/2)}\\ =1/2cos(x/2)\\=\frac{1}{2\sqrt{(cos(x)+1})/2 } \\=\frac{1}{\sqrt{2(1+cos(x))} }[/tex]

Thus, the equivalent expression to[tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]  is  [tex]\frac{1}{\sqrt{2(cosx+1)} }[/tex].

Answer:

Step-by-step explanation:

the expression that represents both sin(57°) and cos(33°) is 15/x

To determine the expression that represents both sin(57°) and cos(33°), we need to use the given information about the triangle.

Let's label the angle opposite the perpendicular side as angle A and the angle opposite the base as angle B.

Since the perpendicular is 15 and the base is 17, we can use the Pythagorean theorem to find the length of the hypotenuse (x):

x² = 15² + 17²

x² = 225 + 289

x² = 514

x = √514

Now, let's analyze the angles. The angle A (opposite the perpendicular) is 33°, while the angle B (opposite the base) is 57°.

Therefore, sin(57°) is represented by 15/x, and cos(33°) is represented by 15/x.

Thus, the expression that represents both sin(57°) and cos(33°) is 15/x

HI BRAYLEYN THIS IS ZAID I FOUND YOU ON BRAINLY  SO I DID A QUESTION LIKE THAT SO I THINK

it's -6 i asked my teacher on this question

Answer:

Her error was that she equated 2x to 6 instead of equating 2x to 3x-5

Step-by-step explanation:

Find the diagram of the question attached.

According to the triangle given, you can see that the base angles are equal. This shows that the triangle is an isosceles triangle. If the base angles are the same, this means that the length of the slant sides are also equal i.e

2x = 3x-5

Get x first;

2x = 3x-5

2x - 3x = -5

-x = -5

x = 5

Get the side length

For side length 2x, the length is 2(5) = 10

For side length 3x-5, the length is 3(5) - 5 = 10.

Hence the length of the sides is 10

Amaya is wrong because she equated the wrong sides. She equated 2x to 6 instead of equating 2x to 3x-5 as shown in the calculation above.

Domain and Range both are real numbers for all odd-degree polynomial functions.

Writing in an Interval Form, note that we use the least value in the left and the most value in the right.

From [a,b], [a,b), (a,b] or (a,b) | a must be less than b.

Therefore, the D choice is wrong in Interval part (However, right in range and domain but just for interval order.)

So the answer is C.

Answer:

15c + 25s ≤ 1500

Step-by-step explanation:

Let the number of stools be s

Let the number of chairs bought be c

If each tools cost $15, s stools will cost $15c

If a chairs cost $25, c chairs will cost $25s

Total costs = 15c + 25s

If the center cannot spend more than $1500, then the required equation will be 15c + 25s ≤ 1500

The inequality sign will be less than and equal to since they cannot spend an amount greater than $1500.

Hence the correct equation is  15c + 25s ≤ 1500

Answer:

We get t= 7.22 and t=0.28

The correct options are Option A and Option G

Step-by-step explanation:

The height h of toy rocket at time t seconds after  launch is given by the equation [tex]h(t) = -16t^2 + 120t + 8[/tex]

We need to find how many seconds  until the rocket is 40 feet?

We are given height of rocket h(t) = 40 feet

and we need to find time t

Using the equation [tex]h(t) = -16t^2 + 120t + 8[/tex] we can find time t

We have h(t)=40

[tex]h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0[/tex]

Now, we will solve the quadratic equation using quadratic formula: [tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

We have a =16, b=-120 and c=32

Putting values and finding t

[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28[/tex]

So, we get t= 7.22 and t=0.28

two of the different sides match

Answer:

Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Step-by-step explanation:

Let amount spent on Lunch = x

Total money Emily brought to the fair = $35

Money Spend on ride tickets and lunch = 16+x

Money Left with Emily = $ 7

We need to find how much Emily spend on lunch

SO,

We can write the equation [tex]16+x+7=35\\[/tex]

As, total money is 35 and $7 are still with emily

Solving to find value of x

[tex]16+x+7=35\\x+23=35\\x=35-23\\x=12[/tex]

So, Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Answer:  A :  23 + x = 12

Step-by-step explanation:  35-16=19  19-7= 12 so 12 is the answer :))
