how do i factor this trinomial 5y^2 — 7y — 6 ​

Answer:

29.50 degrees to the nearest hundredth.

Step-by-step explanation:

First we can find the measure of < CGB by using the Cosine Rule:

cos <CGB = (11^2 - 5.3^2 - 6.9^2) / (-2 * 5.3 * 6.9)

= -0.61936

So m < CGB = 128.27 degrees.

Now we can find the measure of x by using the Sine Rule:

11 / sin 128.27 = 6.9  / sin x

sin x =  6.9 * sin 128.27 / 11

= 0.49248

x = 29.5035 degrees

Answer:

x is around 29.5

Step-by-step explanation:

Let's just use the law of cosines.

[tex]c^2 = a^2 + b^2 - 2ab\cos\angle (ab)\\\\6.9^2 = 5.3^2 + 11^2 - 2\cdot5.3\cdot11\cdot \cos x^{\circ}\\47.61 = 28.09 + 121 - 116.6\cdot\cos x^{\circ}\\~\\cos x^{\circ} = \frac{149.09 - 47.61}{116.6} = \frac{101.48}{116.6}\\~\\x^{\circ} = \arccos\frac{101.48}{116.6}\\~\\x^{\circ} \approx 29.5^\circ[/tex]

Answer:

8m-4=16

8m=20

m=2.5

Step-by-step explanation:

Answer:

2.5

Step-by-step explanation:

4(2m -1)/4 = 16/4

2m-1 = 4

2m = 5

m = 5/2 = 2.5

Answer:

[tex]5.11 \times {10}^{3} \\ = 5.11 \times 1000 \\ = 5110[/tex]

Answer:

5110

Step-by-step explanation:

In order to solve this, we need to know what a "power" in math is, and then we just do the following...

[tex](5.11)(10^{3}) = (5.11)(1000) = 5110[/tex]

Answer:

1.2, 1.6, 2.0

Step-by-step explanation:

Pythagorean theorem

A^2 +b^2=c2

1.2^2+1.6^2=2^2

1.44 + 2.56=4

4=4

Since equation works (4=4), it is a right triangle.

Answer:

the plot points should be: m - (-1,-5) l - (-1,-8) n - (-3,-9)

Step-by-step explanation:

i'm not the greatest at explaining but i'll give it a shot. When you are doing a reflection of plot point shape, you need to reflect it over/under the x or y axis (hence the name "reflection") If you are reflecting over any of the axis, y or x, you need to first find the plot points of the original image. Then, you move over to that same spot to reflect it. For example, the shape 1,1, 1,2, 2,1 and 2,2. that's a square right? right. i would be a little worried if you didn't know that. anyways, you would then move to those points to reflect on the axis. We'll reflect on the y axis. You would then move it to the -1,1, -1,2, -2,1 and -2,2.

i'm super bad at explaining stuff but i hope this helps !

Answer:

D

Step-by-step explanation:

Answer:

the answer is a

Step-by-step explanation:

a is .75 shaded in then there are 5 sections in the shaded area

Answer:

D is the correct option.

Step-by-step explanation:

I used the elimination method to solve this. so we can see that there is 100 boxes and we need to 75 to be shaded. only C and D have 75 squares shaded so we can eliminate A and B. now we have to divide by 5. Square C is divided 3 times while square D is divided 5 times, so square D is correct.

Have a nice day! :-)

Answer:

A Japan and B £38

Step-by-step explanation:

Spain £1=€1.41

more €352.50

€352.50÷1.41 ×1 = £250

Japan £1= ¥188

more ¥39856

¥39856÷188×1 =£212

A) Japan is cheaper

B) £250-£212=£38

Answer:

x - 3.8 = y

Step-by-step explanation:

3.8 - 3.8 = 0

4.2 - 3.8 = 0.4

5.1 - 3.8 = 1.3

7.3 - 3.8 = 3.5

an expression that s equivalent to 36x^4- 100 would be 4(3x²+5)(3x²−5)

Answer:

6.65 kilometers

Step-by-step explanation:

950 * 7 days a week = 6650 meters

6650 meters / 1000 (conversion to kilometers) = 6.65 kilometers

Answer:

6.65  km

Step-by-step explanation:

Let's solve this in a set of fraction forms. Since 1 day is 950 meters, 1 week will be converted to days to be on equal grounds. 1 week = 7 days. Therefore, let us set up a fraction; Let "x" be the variable

[tex]\frac{950}{1}=\frac{x}{7}[/tex]

Step 1: Switch sides

[tex]\frac{x}{7}=\frac{950}{1}[/tex]

Step 2: Apply rule [tex]\frac{a}{1}=a[/tex]

[tex]\frac{x}{7}=950[/tex]

Step 3: Multiply both sides by 7

[tex]\frac{7x}{7}=950\cdot \:7[/tex]

Step 4: Simplify

[tex]x=6650[/tex]

Expressed: [tex]\frac{6650 meters}{1000}[/tex] (convertion to kilometers) = 6.65 kilometers

Therefore, Janet would walk 6.65 km in an entire week

Answer:

(x - 3)² + (y + 2)² = 16

Step-by-step explanation:

The center is determined by what number is subtracted from the variables.

Step-by-step explanation:

We can use Pythagorean Theorem to find leg BC.

[tex]AB^2=AC^2+BC^2[/tex]

[tex]24^2=12^2+BC^2[/tex]

[tex]576=144+BC^2[/tex]

[tex]BC^2=432[/tex]

[tex]BC=\sqrt{432}[/tex]

[tex]BC=2\sqrt{108}[/tex]

[tex]BC=4\sqrt{27}[/tex]

[tex]BC=12\sqrt{3}[/tex]

So, the measure of leg BC is 12√3.
