f(z) = 7 +9.5
for z = 19

Answer:

y is 10

Step-by-step explanation:

first take your imformation and put it into the y intercept from.

Which is y=mx+b

so take the cordinates (5,2) and put it into the y-intercept form.

the 5 is x and the 2 is the y, so

2=m*5+b

Then take the slope of -3 and put it in the y-intecept from

2=-3*5+b

then solve for b

2=-3*5+b

2=-15+b

+15  on both sides

17=b

now you know the equation of the line is

y=-3x+17

now plug in your x to find the y of that cordinate

on the line.

y=-3*9+17

solve

y=-3*9+17

y=-27+17

y=10

Answer:

x≥12, Michael must grow for 12 more months (a year) before he can ride a roller coaster.

Step-by-step explanation:

The inequality to represent how tall you must be to go on a roller coaster is

x≥48 because you must be a minimum of 48 inches tall, 'x' represents how tall you must be

If Michael is already 42 inches tall, that is his base point but you need to know how many more months he will need to grow for.

1/2x represents the amount of months Michael needs to grow, x is the unknown variable we need to solve for which represents the months he needs to grow, 1/2 is how many inches he grows in 1 month

42+1/2x≥ 48

subtract 42 from each side) 1/2x≥6

multiply both sides by 2) x≥12

513.881

Explanation: (Credits to jessy276)

= 5*100+3+10+8*0.1+9*0.009

= 500+3+10+8*0.1+9*0.009

= 500+3+10+0.8+9*0.009

= 500+3+10+0.8+0.081

= 503+10+0.8+0.081

= 513+0.8+0.081

= 513.8+0.081

= 513.881

Answer:

The answer is 513.881

Answer:

a & b are parallel to each other. c and d are also parallel to each other

a & c are perpendicular; b and c are also perpendicular

Explanation: Perpendiculars are when two lines meet to make a 90 degrees right angle. Parallel are two lines that never meet at all. Instead, they have the same distance apart across . Think about it as two different streets.

Answer:

63 members

Step-by-step explanation:

Since each person calls 2 persons each, there is an exponential increase of 2 for each level. Since it starts with the president as 1 person, and increases exponentially by 2 for each level of phone call, we have a geometric progression of first term, a = 1 and common ratio r = 2. Since the process of phone calls must be repeated 5 times, our last term is 2⁵. So, our geometric progression is 2⁰ + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵

We now sum the geometric progression

The sum of a geometric progression with r > 1 is

S = a(rⁿ - 1)/(r - 1)

substituting r = 2, a = 1 and n = 6 since we have 6 terms, we have

S = 1(2⁶ - 1)/(2 - 1)

= (64 - 1)/1

= 63

So, we have 63 members in the club.

We could have also found this by summing up individually the terms in the series. We have 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2 + 4 + 8 + 16 + 32 = 63

Answer:

40%

Step-by-step explanation:

90 is 60% of 150 so that automatically makes the cappuccino 40%

Answer:

£4

Step-by-step explanation:

Adam: 30% of £80

Katy: £28

First, let's fund Adam's bonus. We know that 30% is equal to 0.3. Then, we can multiply £80 by 0.3. This results in £24.

We also know that Katy made £28. Now we need to find the difference.

The difference between Adam and Katy is £4.

Answer:

Step-by-step explanation:

LEt the surface of the ocean be at the zero level i.e at 0metres

If Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level, the distance between Trina and the sea level will be:

D = 0-(-85.6)

D = 0+85.6

D = 85.6m

If Jessie went hang-gliding and reached an altitude of 87.9 meters, the distance between Jessie and the sea level will be:

D = 87.9-0

D = 87.9m

Since the distance of Trina is less than that of Jessie, this means that Trina is closer to the surface of the ocean

Answer:

area = x² - 7x

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 2x and h = x - 7 , thus

A = [tex]\frac{1}{2}[/tex] × 2x(x - 7) = x(x - 7) = x² - 7x

Answer:

a=x^2-7x

Step-by-step explanation:

a=1/2bh

a=1/2(x-7)(2x)

a=1/2(2x^2-14x)

a=x^2-7x

Answer:

The equation is "Y = 56.36*X + 56.47"

Step-by-step explanation:

The form of the equation is  y=mx+b, m = slope and b = intercept.

You have to find the slope of the trend line or you can use the plot points, but identifying the slope in the trend line is much easier.

It seems there are two points that are outliers and need no paying attention to, this is because outliers can make predictions unreliable and also make the trend line unreliable overall as well.

Answer:

A balance diet is a healthy diet that contains different food intakes.

Step-by-step explanation:

A balance diet may be defined as a diet which contains different varieties of food in certain proportions and quantities so as supply the requirements of the body for proteins, vitamins, calories, minerals and nutrients. It is a healthy diet that helps to maintain and improve the overall health.

For a balance diet, a person needs to take proper amount pf carbohydrates, fats and proteins so that the body gets the required energy in terms of calories for the day.

In the context, Isaiah wishes to consumes 2000 calories of energy in one day for a healthy diet. So according to the United States government recommended diet for the consumption of 2000 calories per day, Isaiah should have 15% of protein, 30% of fat and 55% of carbohydrate. And in terms of gram, she should take 75 gram of protein (300 cal), 67 gram of fat (600 cal) and 275 grams of carbohydrates (1100 cal).

Answer:

14

Step-by-step explanation:

By following the exponent rule, when multiplying two numbers of the same term with exponents, you simply add them together.

Therefore, to make (5^n)(5^2)=5^16 true, n must equal 14 since:

14 + 2 = 16

Answer:

n = 14

Step-by-step explanation:

Recall the rule:

[tex] a^m \times a^n = a^{m + n} [/tex]

[tex] (5^n)(5^2) = 5^{16} [/tex]

[tex] (5^n)(5^2) = 5^{n + 2} = 5^{16} [/tex]

[tex] n + 2 = 16 [/tex]

[tex] n = 14 [/tex]
