Answer:

3780 bolts will be made by 8pm

Step-by-step explanation:

One Hour : 500 nuts or 840 bolts

Divide by 2

30 minutes : 250 nuts or 420 bolts

750 nuts : 500 + 250 = 750

so the machine took 1 hour and 30minutes

14:00 it started (2pm)

15:30 it switched to bolts

20:00 (8pm)

4 hours and 30minutes to get to 8pm

840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made

Answer:

Foci [tex](0,\pm\frac{\sqrt{17}}{4})[/tex]

Vertices:[tex](0,\pm 1)[/tex]

Eccentricity, e=[tex]\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

We are given that

[tex]y^2-16x^2=1[/tex]

[tex]y^2-\frac{x^2}{(\frac{1}{4})^2}=1[/tex]

The equation of hyperbola is along y-axis because y is positive

Compare the equation with

[tex]y^2/a^2-x^2/b^2=1[/tex] (Along y-axis)

We get

a=1, b=1/4

[tex]a^2+b^2=c^2[/tex]

[tex]1+\frac{1}{16}=c^2[/tex]

[tex]\frac{16+1}{16}=c^2[/tex]

[tex]c^2=\frac{17}{16}[/tex]

[tex]c=\pm \frac{\sqrt{17}}{4}[/tex]

Therefore,

The coordinates of foci=[tex](0,\pm c)=(0,\pm\frac{\sqrt{17}}{4})[/tex]

The coordinated of vertices=[tex](0,\pm a)=(0,\pm 1)[/tex]

Eccentricity, e=c/a

[tex]e=\frac{\frac{\sqrt{17}}{4}}{1}=\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{2b^2}{a}[/tex]

Length of latus rectum=[tex]2\times \frac{1}{16}=\frac{1}{8}[/tex]

Answer:

[tex]G' = (3,1)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I' = (-2,-3)[/tex]

Step-by-step explanation:

Given

See attachment for points G, H and E

Rotation: 90 degrees clock-wise

Required

Determine the coordinates after rotation

From the attachment:

[tex]G = (-1,3)[/tex]

[tex]H = (0,-4)[/tex]

[tex]I = (3,-2)[/tex]

When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)

So, we have:

[tex]G = (-1,3)[/tex]

[tex]G' = (3,1)[/tex]

[tex]H = (0,-4)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I = (3,-2)[/tex]

[tex]I' = (-2,-3)[/tex]

Answer:

[tex]v = 400000(2^\wedge d)[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Value = \$400000[/tex]

[tex]Rate = doubles[/tex] per decade

Required

Determine the equation of the function

The information given shows that the function is exponential and will be calculated using:

[tex]v = ab^d[/tex]

Where:

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So, we have:

[tex]v = 400000* 2^\wedge d[/tex]

[tex]v = 400000(2^\wedge d)[/tex]

The equation that represents the value of the home is v = $400,00(2^d).

The home is appreciating in value. This means that the price of the house is increasing with the passage of time.

The formula that can be used to represent the appreciation is:

FV = P (1 + r)^n

v = $400,000(2^d)

The triangle in which the side are nine inches long has a perimeter of 27 inches.

The perimeter of a triangle is the sum of the length of the whole side.

The triangle have three sides and the perimeter is the sum of the whole sides.

According to the question, the triangle has the whole sides as 9 inches.

This means the triangle is an equilateral triangle.

Therefore,

length of side = 9 inches

perimeter = 9 + 9 + 9

perimeter = 27 inches

Step-by-step explanation:

Sasha needs to collect 120 more cans to reach her goal.

let us say the total goal is 100x

it is given that

when she collected 180 cans she knew she had reached 60% of her goal.

it is made up of two words 'per' and 'cent' means it is the value out of a hundred.

60% of 100x= 60x

60x = 180(given)

x=3

total goal = 100x= 100*3=300

total goal left= 300-180=120

therefore, Sasha needs to collect 120 more cans to reach her goal.
