If y is directly proportional to x and y =1200 when x=30, then what is the value of x when y=30?

Answers

Answer 1

Answer:

Y= 30

X= 0.75

Step-by-step explanation:

If the first Y was 1,200 and X was 30, then that means every time your divide Y by 40, you will get your X. It's the exact opposite if you want to find Y.

So you want to divide your Y, which is 30, by 40. Once who find your answer, you should have gotten 0.75 for X.

Why divide by 40? Good question. You divide by 40 because if you multiply your X example Y= 1,200, X= 30, you will get 30x40 which is 1,200. Do it the other way around divide 1,200 by 40, you get 30.

All in all your answer should be X= 0.75. If not tell me.

Thank You For Your Time

What is the value of g(f(x)) ? Ο Α. . -6 OB. C. 19 D. 31

Answers

Answer:

D. 31

Step-by-step explanation:

Given:

[tex] f(x) = 4x^3 - 10 [/tex]

[tex] g(x) = \frac{3x - 4}{2} [/tex]

Required:

The value of g(f(2))

First, find f(2).

Substitute x = 2 into [tex] f(x) = 4x^3 - 10 [/tex].

[tex] f(2) = 4(2)^3 - 10 [/tex]

[tex] f(2) = 4*8 - 10 = 32 - 10 [/tex]

[tex] f(2) = 22 [/tex]

Next, find g(f(2)).

[tex] g(f(x)) = \frac{3(22) - 4}{2} [/tex]

[tex] g(f(x)) = \frac{66 - 4}{2} [/tex]

[tex] g(f(x)) = \frac{62}{2} [/tex]

[tex] g(f(x)) = \frac{62}{2} [/tex]

[tex] g(f(x)) = 31 [/tex]

You have a rock with a volume of 15 cm3 and a mass of 45 g. What's its density?

Answers

The formula for density is d = m/v.

d = density

m = mass

v = volume

The volume of the rock is 15 cubic centimeters.

The mass of the rock is 45 grams.

Now just plug these into the formula and solve.

d = 45/15.

45/15 = 3.

The density of the rock is 3 grams per cubic centimeters.

Given:

Mass of the rock = 45 g

Volume of the rock = 15 cubic cm

Formula:

Density = Mass / Volume

Explanation:

By putting the respected values, we get

Density = 45 g / 15 cubic cm = 3 gram/cubic centimeter

Answer:

Density of the rock is 3 gram/cubic centimeter.

Brandon is going to invest in an account paying an interest rate of 5% compounded quarterly. How much would Brandon need to invest, to the nearest dollar, for the value of the account to reach $490 in 16 years?​

Answers

Answer:

Brandon wants $490 in 16 years by investing "x" dollars in an account that pays  5% compounded quarterly.   How much is "x"?

Principal = Total / [ (1 + (r/n) )^ n * years]

n = 4 (for compounded quarterly)

Principal = 490 / [ (1. + (.05/4)) ^ 4 * 16]

Principal = 490 / [ (1.0125)^ 64]

Principal = 490 / 2.2145324106

Principal = 221.2656710971

So, if we invested 221.27 for 16 years at 5% compounded quarterly interest,  we would have a total of $490.00

a) 0.1003
b) 0.3997
c) 0.6003
d) 0.8997
e) 0.0003

Answers

Answer:

A: 0.1003

Step-by-step explanation:

We are given;

Population mean; μ = 56.8

Population size; n = 51

Population standard deviation; σ = 12.3

We want to find; P(x > 59)

We will use the z-score formula.

z = (x - μ)/(σ/√n)

z = (59 - 56.8)/(12.3/√51)

z = 1.28

From z-distribution table attached, we have; P(z < 1.28) = 0.8997

Thus;

P(z > 1.28) = 1 - 0.8997 = 0.1003

Answers

Answer:

The rational function that might have the given graph is [tex]y = - \frac{x}{(x+1)\cdot (x-1) }[/tex].

Step-by-step explanation:

This graph shows a rational function whose numerator is a first order polynomial and denominator is a second order, due to the presence of vertical asymptotes at [tex]x = -1[/tex] and [tex]x = 1[/tex]. The lead coefficient of the numerator must be 1, since horizontal asymptote must be [tex]y = 0[/tex] and intercept must be [tex]0[/tex], since [tex]y(0) = 0[/tex].

Then, we conclude that a rational function that might have the graph is:

[tex]y = - \frac{x}{(x+1)\cdot (x-1) }[/tex] (1)

For the triangles described, which of the following statements must be true? In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. In triangle PQR, PQ=23 in., PR=8 in., and ∡P=16°. (1 point) ∠Q≅∠F ∠R≅∠F DE¯¯¯¯¯¯¯¯≅PQ¯¯¯¯¯¯¯¯ ∠E≅∠Q

Answers

Answer:

∠Q≅∠F

Step-by-step explanation:

Two triangles are said to be congruent if all the three sides of the triangles are equal and all the three angles are equal.

Given that: In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. In triangle PQR, PQ=23 in., PR=8 in., and ∡P=16°.

Hence we can say that ΔDEF is congruent to ΔPQR. According to the side-angle-side (SAS) triangle congruence theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Therefore:

DF = PQ, DE = PR, EF = RQ, ∠D = ∠P, ∠E = ∠R and ∠F = ∠Q

1. Slope of segment BC
2. Slope of segment AD
3. Length of segment BC
4. Length of segment AD
5. ABCD is a ________

Answers

Answer:

Step-by-step explanation:

1 and 2.

slope is m = ( y2-y1) / (x2-x1)

slope of BC = 5-3 /6-1 = 2/5

slope of AD = 1 +1 / 7-2 = 2/5

3 and 4

use the distance formula d= √(x2-x1)² +(y2-y1)²

BC = √( 6-1)²+(5-3)² = √5²+2²= √29

AD = √(7-2)²+(1+1)² = √5²+2² = √29

5.

since BC and AD have the same slope then they are parallel

since BC and AD are same length the segments are ≅

so ABCD is a rectangle
