Answer:

[tex]a=49[/tex]

Step-by-step explanation:

You would solve this the same way you would with any other triangle problem. You will plug in for the base and the height in this formula [tex]a=\frac{1}{2}bh[/tex].

[tex]a=\frac{1}{2}bh\\a=\frac{1}{2}(\sqrt{343})(\sqrt{28})[/tex]

Now we will multiply the two radicands.

[tex]a=\frac{1}{2}\sqrt{9604}[/tex]

For this we will split the 9604 into 49 and 196.

[tex]a=\frac{1}{2}\sqrt{49}\sqrt{196}[/tex]

Now we just take the square roots of those two and since they're perfect squares they'll be whole numbers.

[tex]a=\frac{1}{2}(7)(14)[/tex]

Next we just multiply everything together.

[tex]a=49[/tex]

Answer:

-2

Step-by-step explanation:

I actually just did functions in math at the end of last semester I offer you my condolences dude

The slope of the function that passes through two points (-2, 12) and (4,0) is -2

Slope of the function is calculated by find the rate of change of y over rate of change of x.

The formula to fidn out the slope is

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

The function passes through two points (-2,12) and (4,0)

substitute the points and find out the slope of the fuction

(x1,y1) is (-2,12)  

(x2,y2) is (4,0)

Substitute the values

[tex]slope =\frac{0-12}{4+2}=\frac{-12}{6} =-2[/tex]

The slope of the function that passes through two points (-2, 12) and (4,0) is -2

Answer:

0.9696

Step-by-step explanation:

Given that:

Mean, m = 79

Standard deviation, s = 8.2

Sample size, n = 35

Probability that final exam grade of the sample is between 76 and 82

P(76 < x < 82)

P(x < 82) - P(x < 76)

Using the relation :

Z = (x - m) / (s/sqrt(n))

s / sqrt(n) = 8.2/sqrt(35) = 1.3860529

P(x < 82) - P(x < 76)

P[(82 - 79) / 1.3860529] - P[(76 - 79) / 1.3860529]

P(Z < 2.1644) - P(Z < - 2.1644)

Using the Z probability calculator :

0.98478 - 0.015217

= 0.969563

Hence, probability = 0.9696

Step-by-step explanation:

Answer:

y = 2x + 3

Step-by-step explanation:

I guess you mean

(1 + i ) / (1 - i ) + 1 / (1 + i )

in which case, notice that the denominator of both fractions are conjugates of one another. Combine the fractions by multiplying either fraction by the appropriate conjugate:

[(1 + i ) / (1 - i ) • (1 + i ) / (1 + i )]+ [1 / (1 + i ) • (1 - i ) / (1 - i )]

In either denominator, we have a difference of squares:

(1 + i ) (1 - i ) = 1² + i - i - i ² = 1² - i ² = 1 + 1 = 2

→   (1 + i )² / 2 + (1 - i ) / 2

→   ((1 + i )² + (1 - i )) / 2

Expand the numerator:

(1 + i )² + (1 - i ) = (1² + 2i + i ²) + 1 - i = 1 + 2 - 1 + 1 - i = 3 - i

and so

(1 + i ) / (1 - i ) + 1 / (1 + i ) = (3 - i ) / 2

Answer x=12

Step-by-step explanation:

5/2x-7=3/4x+14

      +7.         +7

5/2x=3/4x+21

-3/4x -3/4x

5/2-3/4=7/4x

7/4x=21.         since there's a fraction on one side, multiply 4 with 21

7x=84

divide and you'll get x=12

[tex] \frac{5}{2} x(4) - 7(4) = \frac{3}{4} x(4) + 14(4) \\ 10x - 28 = 3x + 56[/tex]

[tex]10x - 3x = 56 + 28 \\ 7x = 84 \\ x = \frac{84}{7} \\ x = 12[/tex]

[tex] \large \boxed {x = 12}[/tex]

what's the question xjsbzbksns

Answer:

what r u asking?

Step-by-step explanation:

Given :

Actual length of the bolt is 2.5 inches.

Measured length of the bolt is 2.6 inches.

To Find :

The percent error of the bolt.

Solution :

We know, percentage error is given by :

[tex]\delta =| \dfrac{Actual\ Value - Expected\ Value}{Expected\ Value}|\times 100\\\\\delta =| \dfrac{2.6-2.5}{2.5}|\times 100\\\\\delta = 4 \%[/tex]

Therefore, the percentage error in the bolt is 4% .

Answer:

-3

Step-by-step explanation:

If x+2y= -3, then x= (-3) -2y because when you take away 2y from one side, you take it away from the other.

5(-3-2y) + y= 12 means that y= -3

Answer:

Answer:

[tex]f'(x) = 2x - 10[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x + 4[/tex]

Required

Translate 7 units left

When a function f(x) is translated b units to the left, the resulting function is:

[tex]f'(x) = f(x-b)[/tex]

In this case:

[tex]f(x) = 2x + 4[/tex]

[tex]b = 7[/tex]

[tex]f'(x) = f(x-b)[/tex] becomes

[tex]f'(x) = f(x - 7)[/tex]

Calculating [tex]f(x-7)[/tex]

[tex]f(x-7) = 2(x-7)+4[/tex]

[tex]f(x-7) = 2x-14+4[/tex]

[tex]f(x-7) = 2x-10[/tex]

So:

[tex]f'(x) = 2x - 10[/tex]

7/8 is equivalent to 56/64
