Solve the equation for x and y​

Answer:

0.35 as a decimal and  7/20 as a fraction

Step-by-step explanation:

Answer:

x = 53°

Step-by-step explanation:

The angle 115° and the angle formed by the sum of x+62° are external alternates angles, so it means they have the same measure, and you can find the value of x doing:

115°- 62° = 53°

Answer:

[tex] \frac{5}{18} = 0.27[/tex]

Step-by-step explanation:

[tex] \frac{(4 - 5)^{2} + {(2 + 1)}^{2} }{ {(4 + 2)}^{2} } [/tex]

[tex] = \frac{ {( - 1)}^{2} + {3}^{2} }{ {6}^{2} } [/tex]

[tex] = \frac{1 + 9}{36} [/tex]

[tex] = \frac{10}{36} [/tex]

[tex] = \frac{5}{18} [/tex]

= 0,27

the sequence is arithmetic because it's incrementing by a constant ratio of -4

The sequence 11,7,3,... is arithmetic because there is a constant increase of (-4)

At the given zeros of the function (-1.5, -1, and 2), the graph will behave like a sine curve, cutting the x-axis at three points.

The given polynomial expression:

y = 2x³ + x² - 7x - 6

The zeros of a polynomial equation are the values of x at which the given function equals zero.

The first zero of the given function is at x = 2;

f(2) = 2(2)³  + (2)²  - 7(2)  - 6

     = 16   +  4  - 14  - 6

     = 20   -    20  =  0

The second zero of the given function is at x = -1;

f(-1)  = 2(-1)³  + (-1)²   - 7(-1)   -   6

      = -2    +   1   +   7   -  6

      = - 8  +  8 =  0

The third zero of the given function is at x = -1.5;

f(-1.5)  = 2(-1.5)³   +  (-1.5)²   -  7(-1.5)   -  6

          = - 6.75    +  2.25   + 10.5    -  6

          = - 12.75  + 12.75  = 0

The zeros of the given function include;

----(-1.5)-------(-1)------------------------------(2)--------

Therefore, at the given zeros of the function (-1.5, -1, and 2), the graph will behave like a sine curve, cutting the x-axis at three points.

BC^2=1+64

BC^2=65

BC=√65

BC=8.06

Answer:

Step-by-step explanation:

The mode is the most number of times a number appears in a set of data points.

If there is at least one entry in the data set, then there is at least 1 mode. You can have more than 1 mode.

3, 3, 3, 5, 6, 6,  6  has 2 modes. (3 and 6)

3 has 1 mode.

[  ] set has no modes because this is the empty set.

Conclusion

A is not true. See the example above

B is true. It can have more than 1 mode

C is true for everything but the empty set.

D is simply false.

I think you are intended to pick C, but B is also true. I can't give you just 1 answer. It is a faulty question.

Answer:

i) around 41.7 kg

ii) 72 books

Step-by-step explanation:

i) if 108 books are 30 kg then how much is the mass for 150? You cross multiply so 150 multiply by 30 and 108 multiply by x (the unknown mass). you will get 4500=108x and then 4500/108 is the unknown mass.

ii) use the same way as above.

Step-by-step explanation:

Hi there!

Given;

= 5(π\6)

We have;

π = 180°

Keeping value of π in the question;

= 5(180°/6)

= 5*30°

= 150°

Therefore, answer is option B.

Answer:

Hello,

Answer 52/3

Step-by-step explanation:

using the theorem of the bissector :

[tex]\dfrac{x}{13} =\dfrac{20}{15 } \\\\x=\dfrac{20*13}{15} \\\\x=\dfrac{52}{3}[/tex]

The value of x to the nearest tenth is 18.5

To get the value of x, we first need to get the height of the triangle.

[tex]h^2=20^2-15^2\\h^2=400-225\\h^2=175\\h=13.23[/tex]

Next is to get the value of x

[tex]x^2=13^2+13.2^2\\x^2=343.24\\x=18.52[/tex]

Hence the value of x to the nearest tenth is 18.5

One property of logarithms is that you can use the small number under the log and raise it by the number on the other side of the log. Once the number raised, the log will disappear. You can then solve like normal.

The value of m is -4 and 3/4.

In mathematics, the logarithm exists as the inverse function to exponentiation. That represents the logarithm of a provided number x exists the exponent to which another fixed number, the base b, must be raised, to produce that number x.

we know this logarithmic law :-

[tex]log_1_0P=x[/tex]

converted to indices :-

[tex]10^x=P[/tex]

therefore,

[tex]log_1_0(2m^{2} + 5m -2) = 10^{1}[/tex]

2m²+ 5m-2=0

2m²+8m-3m-12 =0

2m(m+4)-3(m+4) =0

(m+4) (2m-4) =0

m = -4 or m= 3/4

The value of m is -4 and 3/4.

Answer:

17 terms

Step-by-step explanation:

Let the number of terms be n which will add up to 425.

So, 425=(n/2)*(2+(n-1)*3). 850=n*(3n-1), n=17 or - 50/3 but n can't be negative, so the answer is n=17
