El valor numérico de la expresión 〖P(y)=y〗^2-7y+10 para y=2 es: a. P(2)=9 b. P(2)=0 c. P(2)=-2 d. P(2)=-5
Answer:
Opción b, P(2) = 0
Step-by-step explanation:
Tenemos la expresión:
P(y) = y^2 - 7*y + 10
Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:
P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0
P(2) = 0
La opción correcta es b.

What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m
Answer:
V = pi*r^2*h
V = 150 m^3
h = 8 m
150 = pi*r^2*8
Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.
V = 1/3 pi r^2 h
Diameter of the cone is 15 m. So, option D is correct.
What is meant by solid shape ?Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.
Here,
Volume of the cone is given by,
V = 150[tex]\pi[/tex] m³
Height of the cone, h = 8 m
We know, the equation for the volume of a cone is,
V = 1/3[tex]\pi[/tex]r²h
where r is the radius and h is the height of the cone.
So,
(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]
r²x 8 = 3 x 150 = 450
r² = 450/8
r² = 56.25
r = 7.5 m
Therefore, diameter of the cone,
d = 2r
d = 2 x 7.5
d = 15 m
Hence,
Diameter of the cone is 15 m.

Find the area of a nonagon with a perimeter of 126 inches. Round to the nearest tenth.
Answer:
Step-by-step explanation:
A=1/36P2cot(20°)=1/36·1262·cot(20°)≈1211.63754in²
I hope this helped.!
Answer:
area = 1217.16 in²
Step-by-step explanation:
a nonagon has 9 sides
each side = 126/9 = 14 inches
it forms 9 identical isosceles triangles with a base of 14
each top angle = 360/9 = 40°
the area of each triangle can be found by the formula area = 1/2(base)(height)
We know the base is 14
the height would be calculated be constructing a perpendicular line from the top of the triangle and perpendicular to the base. This smaller triangle base is 1/2 of 14, or 7 inches. it's top angle is 1/2 of 40°, or 20°
the height of smaller triangle is the same height as the larger triangle.
tan 20° = 7/height
0.3640 = 7/x
0.3640height = 7
height = 19.32 inches
area of larger triangle = 1/2(14)(19.32) = 135.24 in²
total area = 9 x 135.24 = 1217.16 in²

So you go to the store one day with 50$ to spend. You wanna buy some apples and some pears. The apples are 5$ per pack (3 in each pack) and the pears are 3$ each pack (4 in each pack.) you end up buying 5 packs each fruit. How much money do you have left over?
Answer:
10$
Step-by-step explanation:
Answer:
$10
Step-by-step explanation:
Honestly, who eats that much fruit? but okay, we'll start with finding how much money she spent, and apples will go first:
So this is basically dealing with rates, so you just gotta multiply:
5 x 5 = 25
So you spent an unnecessary $25 on apples, now let's go to pears:
3 x 5 = 15
So you spent $15 on pears, now we combine those two:
25 + 15 = 40
So you spent $40 on fruit
So now we want to know how much money we have left, so we're gonna subtract:
50 - 40 = 10
So you have $10 left over

The ratio of boys to girls in a gym class is 5:3. There are 27 girls in the class. How many boys are in the class?
Answer:
There are 45 boys in the gym class.
Step-by-step explanation:
Set up an equation:
Variable x = number of boys in the class
5/3 = x/27
Cross multiply:
5 × 27 = 3 × x
135 = 3x
Divide both sides by 3
45 = x
Check your work:
5/3 = 45/27
5 × 27 = 3 × 45
135 = 135
