Answer:the answer is 3/2

Step-by-step explanation:

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Dividing equally 6 cups of jams into 4 containers.

= 1.5 cups / 1 container

The amount of jam in each container is 1.5 cups of jams.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Jada made 6 cups of blueberry jam and divided the jam equally among 4 containers.

The amount of jam in each container.

= 6 cups / 4 container

= 1.5 cups / 1 container

This means that in each container there are 1.5 cups of jams.

Thus,

Dividing equally 6 cups of jams into 4 containers.

1.5 cups / 1 container

The amount of jam in each container is 1.5 cups of jams.

Answer:

x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130\\}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]

Step by step:

Step 1: Subtract -5 from both sides.

8x2+16x−62−(−5)=−5−(−5)

8x2+16x−57=0

For this equation: a=8, b=16, c=-57

8x2+16x+−57=0

(plus-minus) = ±

Step 2: Use quadratic formula with a=8, b=16, c=-57.

x=[tex]\frac{-b(plus-minus)\sqrt{x} b^2-4ac}{2a}[/tex]

x=[tex]\frac{-(16)(plus-minus)\sqrt{(16)^2-4(8)(-57)} }{2(8)}[/tex]

x=[tex]\frac{-16(plus-minus) \sqrt{2080} }{16}[/tex]

ANSWER:

x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]

Answer:

  x ≈ 2.367796

Step-by-step explanation:

There are a number of ways to use "successive approximation" to find a solution to an equation. You have not specified the method or the required accuracy.

__

One of the more tedious is the bisection method, which computes the value of the function at the midpoint of an interval, to see if that midpoint should be a new interval bound. This method requires about 3 iterations per decimal place of the answer.

Another method is the secant method. It computes the x-intercept of the secant line joining the points at the ends of the interval containing the solution. The function value at this x-intercept is used to see if that point should be a new interval bound. This method converges slightly faster than the bisection method. It is speeded by adjusting both ends of the interval.

Newton's method iteration converges at a quadratic rate, nearly doubling the number of correct decimal digits at each iteration. This works in a fashion similar to the secant method, except the x-intercept is computed from the function value and its derivative, not from points at the ends of an interval.

__

We assume you want the solution to ...

  x^2 -5 = √(x -2)

This is conveniently reformulated to ...

  x^2 -5 -√(x -2) = 0

so that we're seeking a zero of the function on the left.

The attached shows several iterations of the secant method. The function g is used to compute the x-intercept point on the line between (x1, f(x1)) and (x2, f(x2)). Then f(g( )) computes the function value at that x-intercept. We have used that to decide what the next interval limits (x1, x2) could be.

Our final guess at x is ...

  x ≈ 2.367796 . . . . secant method

which gives an error less than 10^-5 between the left- and right-sides of the equation.

Additional comments

At the bottom of the attachment is the Newton's Method iterator. The nice thing about this graphing calculator is that it displays the result of computing h(x) even as the value of x is being typed. This means you can type what you see and achieve full calculator precision for the solution in basically one pass. This method gives x = 2.36779701571.

Some hand-held graphing calculators have a derivative function built-in, so it is practical to use them to perform Newton's method iteration in substantially the same way.

The range of milk production that 95% of the cows will fall within is option B: 4.8 gallons to 7.6 gallons.

To find the range of daily milk production that 95% of the cows will fall within, we can use the empirical rule, which states that for a normal distribution:

About 68% of the observations fall within one standard deviation of the mean.

About 95% of the observations fall within two standard deviations of the mean.

About 99.7% of the observations fall within three standard deviations of the mean.

Since we are looking for the range of milk production that 95% of the cows will fall within, we need to find the range that is within two standard deviations of the mean. That range is:

Mean ± 2SD

= 6.2 ± 20.7

= 6.2 ± 1.4

= [4.8, 7.6]

Answer:

16/5

Step-by-step explanation:

Answer:

The answer is 15/2 and the simplified answer is 7 1/2.

Step-by-step explanation:

To turn 2 1/2 into a normal fraction you need to multiply 2 and 2 ao it will be 2x2 and then you add the 1 which gets you 5.You keep the denominator and the fraction is now 5/2.Dividing fractions is the same as multiplying fractions so all you have to do is flip 1/3 and now it us 3/1 then you turn the division symbol into a multiplication symbol and multiply both numbers.5x3 = 15 and 2x1 = 2 so now you have 15/2 and if you wanted to simplyfy it you need to see how many times 2 can go into 15.2 can go into 15 7 times because 2 x 7 = 15 and if we multiply 2 x 8 it will be 16 which would be too much.We have 1 number left over since we were 1 number behind so we put 1 as our numerator and keep 2 as out denominator so now we have 7 1/2.

Answer:

No, the triangles are not similar.

Step-by-step explanation:

For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180

180-70=110, 110-58=52       ∠N = 52°

since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.

or this

f(x) = 6^x becomes g(x)= 6^(x -9) so it went RIGHT 9 units

Answer:

Step-by-step explanation:

so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10

i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive

so we have 1x + 6 + -6x + 10

we can add 6 and 10 and 1x and -6x make an end result of

-5x + 16

(or the other way since it is addition)

Answer:

We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

[tex]y = mx+b[/tex]

where

Important Tip:

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

[tex]18x + 9y = -416[/tex]

subtract 18x from both sides

[tex]18x+9y-18x = - 18x-416[/tex]

simplify

[tex]9y = -18x - 416[/tex]

divide both sides by 9

[tex]y=-2x-\frac{416}{9}[/tex]

Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation

Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.

Hence, option D is correct.

Answer:

i believe it is 73 degrees

Step-by-step explanation:

Answer:

73°

Step-by-step explanation:

All interior angles of a triangle add up to 180°

We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.

90 + 17 = 107

180 - 107 = 73

The third angle should be 73°. Hope this helps!
