Answer:

the answer would be d on pshc

Answer:

Option C, both functions have an y-intersect equal to 2.

Step-by-step explanation:

When we have a function f(x), the y-intercept is the value f(0). This is the point where the graph of the function intersects the y-axis.

Then, for f(x) = -x^2 + 5*x + 2

The y-intercept is:

f(0) = -0^2 + 5*0 + 2 = 2

f(0) = 2

And for g(x) we do not have the equation, but we have the graph, so we can just look at which value of y does the graph intersects the y-axis.

We can see that the graph intersects the graph at y = 2

Then the y-intersect is: g(0) = 2

So both functions have the same y-intersect. Then the correct option is C.

Answer:

3a²b

Step-by-step explanation:

The product of two algebraic

terms is 6a3b2. If one of the terms is

2ab, find the other term.

Let us represent

First term = a

Other term = b

a × b = 6a³b²

a = 2ab

b = ?

b = 6a³b²/a

b = 6a³b²/2ab

b = 6a³b²/2a¹b¹

b = (6 ÷ 2) × a^3 - 1 × b ^2 - 1

b = 3a²b

Therefore, the other term = 3a²b

Answer:

If "x" is the degree measure of the given angle, then the measure of its complement is (x+50) degrees.

And since these angles are complementary, you have this equation x + 50 = 90 °

x = 90 - 50

x = 40 °

The other angle is 40 °

Answer:

[tex]V=2143.57\ mm^3[/tex]

Step-by-step explanation:

Given that,

The radius of the sphere, r = 8 mm

We need to find the volume of the sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\times 3.14\times 8^3\\\\=2143.57\ mm^3[/tex]

So, the volume of the sphere is equal to [tex]2143.57\ mm^3[/tex].

Answer: The answer is 1,853 <3

Step-by-step explanation:

Step-by-step explanation:

1) solution

Hypotenous(h)=?

perpendicular(p)=16

base(b)=12

By using formula

h^2 = p^2 + b^2

h^2 = 16^2 + 12^2

h^2 = 256 + 144

h^2 = 400

h^2 = 20^2

h = 20

therefore hypotenous (h) is 20

2) solution

hypotenous = (?)

perpendicular=(77)

base=(36)

by using formula

h^2 =p^2 + b^2

h^2=77^2+ 36^2

h^2=5929+1296

h^2=7225

h^2=85^2

h=85

therefore hypotenous (h) is 85

Answer:

$18,781.5

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Loan amount (P) = $15,000

Rate of interest (r) = 23%

Time (t) = 5 years

Let this loan is compounding annually, then the amount after 5 years can be calculated as follows,

Final amount = P  [tex](1 + ( r/t))^{t}[/tex]

by putting the value in formula, we get

= $15,000 (  [tex](1 + ( 0.23/5))^{5}[/tex]

= $15,000 × 1.2521

= $18,781.5

y^0 = 1

Thus :

y^5 ÷ 1 = y^5

Las longitudes de las diagonales son √41 dm y 10 cm respectivamente

La medida de la diagonal de un rectángulo: de lado l1 y l2 es igual a

d² = (l1)² + (l2)²

La diagonal entonces es: utilizamos la fórmula dadas para los lados dados y aplicando raíz en la ecuación

A. 5dm y 4dm

d = √((5 dm)² + (4 dm)²) = √(25 + 16) dm = √41 dm

B. 8cm y 6cm

d = √((8 cm)² + (6 cm)²) = √(64 + 36) cm = √100 cm = 10 cm .

Answer:

D 15 is the most reasonable prediction of the number of times chocolate is selected if only 81 students are surveyed.

Step-by-step explanation:

all Talley's together equal to 28. there is 5 chocolate out of the 28 Talley's.

5/28 = 0.178571429

0.178571429*81 = 14.4642857

so around 15 times. (I think)

Answer:

1193.2 sq. in.

Step-by-step explanation:

SA = LA + 2B    

where LA is the lateral area and B is the area of the base (circle)

B = πr^2 = 3.14(10)^2 = 3.14(100) = 314

Area of 2 Bases = 2 (314) = 628

LA = Ch    where C is the circumference of the base

LA = πdh = 3.14(20)(9) = 565.2

SA = 628 + 565.2 = 1193.2 sq. in.

Answer:

$24

no, it is 48% off normal price

Step-by-step explanation:

clearance price = normal price - value of the 40% discount

value of the 40% discount = 0.4 x $50 = $20

Price = $50 - $20 = $30

final price = clearance price - value of 20% coupon

value of 20% coupon = 0.2 x $30 = $6

final price = $30 = $6 = $24

total value off normal price = $24 /$50 x 100 = 48%

Therefore , the solution to the given problem of surface area comes out to be 24 square unit.

Shape is a unit used to describe how much overall space a material's surface occupies. A three-dimensional shape surface area is equal to the sum of its surroundings. The overall surface coverage of a multi shape is referred to as surface area. The volume of water of a cube featuring five rectangular faces can be calculated by adding up each face's specific area. As an alternative, you can identify the box's measurements using the formula below: Surface (SA) is equal to two times two times two. 

Here,

The presented parallelogram has a height of 5-2 = 3 units.

The given parallelogram's basis is comprised of => 7 -(-1) units => 8 units.

As a result, the supplied parallelogram has a surface area of 8 * 3 = 24 square units.

As a result, 24 square units are required to solve the given area problem.
