i don’t understand trig at all

Answer:

The answer to this question should be acute

I'm not 100% sure about this because this unit confused me but...

if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)

that point is (0.571, 0) so it's the first option

Answer:

45

This is your answer.

Answer:a = 9 r^2

Step-by-step explanation:

We need to make a subject of the formula given r = square root a / 3

Given r = √a / 3 -------------1

Now we can find a.

Squaring the given equation 1 we get

So r^2 = (√a / 3)^2

So r^2 = a / 9

Answer:

32 oz for $3.00

Step-by-step explanation:

1.25/12 = 0.10416666

1.65/16 = 0.103125

3/20 = 0.15

3/32 = 0.09375

Answer:

temperature will remain 0° after 2 day

Answer: 78.5

Step-by-step explanation:

Formula: A=pi*r^2   or   Area = 3.14*radius squared (by two)

A = 3.14*10^2

A = 3.14*100

A = 314

Divide it by 4, because it's a quarter of the circle: A = 314/4

A = 78.5

Answer: 78.5

Answer:

La torre de pisa esta inclinada de modo que su pared lateral forma un triangulo rectangulo de catetos 5mtrs y60mtrs cuanto mide el otro lado de la torre !

RESOLVEMOS POR EL TEOREMA D EPITÁGORAS

Primero lado = 5 m

Segundo lado = 60 m

Lo que mide el otro lado es = x

Calculamos:

h² = a² + b²

h² = (5 m)² + (60 m)²

h² = 25 m² + 3600 m²

h² = 3625 m²

h = √3625 m²

h = 60,20 m

Rpt. El otro lado mide 60,20 m aproximadamente

<C=12/13

Answer:

y=2x+3

x=(-1)

y=-5x+6

x=1

Step-by-step explanation:

Just find x in the equation

Let length, width, and height be s.

Then diagonal of any face would be √( s² + s² ) = √( 2s² )

And we know that it measures  √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.

Now we have to solve √( 500 ) = √( 2s² )

Square both sides:

500 = 2s²

Divide both sides by 2:

250 = s²

Take the square root of both sides:

√(250) = s ≈ 15.8113883

Rounding to nearest tenth:

s ≈ 15.8

Final answer: 15.8

Hope this helps.

Answer:

1. $624.86

2. 1.99x

3. 2.6 pounds

Step-by-step explanation:

1. Multiply 1.99 by 314 to get 624.86

2. With the equation 1.99x, you can substitute any variable into it and it will hold true.

3. Divide 5.17 by 1.99, the price, and you get 2.597 pounds, which rounds to 2.6

Answer:  244.92 m

Step-by-step explanation:

The area of a circle is pir^2. First you will need to find the area of the concrete and subtract the area of the flower bed from that amount. The concrete is 3 feet wide so you will add that to 11.5 (half of the flower bed diameter) to find the radius. 14.5^2 pi is the entirety of the area. Then subtract 11.5^2 pi for the area of the concrete.

Answer:

Step-by-step explanation:

1.Rewrite the decimal number as a fraction with 1 in the denominator

2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10

3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,

so the answer is

0.4= 2/5

Answer:

The relationships are correct and valid

Step-by-step explanation:

The correct question is as follows;

Verify the following

i.[ -3/4]^3 = -27/64

ii. [-2/3]^6 = 64/ 729

We have the solution as follows;

i) we have;

(-3/4)^3

That means ;

-3^3 = -3^3 = -27

4^3 = 64

so;

(-3/4)^3 = -27/64

ii) (-2/3)^6

(-2)^6 = 64

3^6 = 729

Thus;

(-2/3)^6 = 64/729

Answer:811.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

(7.5ftx9ftx12ft)+[5(9ftx12ft)+2(1/2x5x√(4.5^2+1.5^2)ft)]

=810ft+[540ft+2(1/2x5x6.75)ft]

=810ft+(540ft+33.75ft)

=1383.75ft

(sorry I'm not too sure if it is correct )

Answer: dont get the question sry

Step-by-step explanation:

Answer:

y =-4

x = 1

Step-by-step explanation:

Add the two equations

4x - y + 6x + y = 8 + 2 add like terms

10x = 10 divide both sides by 10

x = 1  now to calculate y replace x in first equation by 1

4x - y = 8

4 - y = 8 subtract 4 from both sides

-y = 4 and y = -4

Answer:

1512 cm^3

Step-by-step explanation:

the small ones dimentions are 9 by 3 by 7

if you double that then it is 18 by 6 by 14

to figure out the volume you have to multiply all the numbers together

and you get 1512 cm^3
