As part of a survey, 150 students were asked if they eat breakfast on school days. Of these students, 45 stated they eat breakfast on school days What percentage of the students in the survey stated they eat breakfast on school days?

Answer:

Y = a(x-h)^2 +k

Step-by-step explanation:

The first one, since the vertex form is in subtraction form. You need the a, the x, the h, and the k for the formula.

Answer:

y=a(x-h)^2+k

Step-by-step explanation:

This is the answer because numbers in the -h and k is the vertex point in this form.

e.g. y=2(x-4)^2+5

the vertex here is (4,5)

(btw, for h, when there's a negative sign in front of it, it's the opposite and when there's a plus sign in front of h, it's the opposite.)

Answer: the letter B.

Answer:

one (Roman numeral one)

Step-by-step explanation:

Because the line goes straight like she is climbing up the hill at a steady pace then boom! all of a sudden she is falling down the hill and gaining major amounts of momentum causing the line to go up as she gets faster and faster.

Answer:

The clock shows 8:18

Step-by-step explanation:

Answer:

8:18

Step-by-step explanation:

Answer:

a) A =( x^2 -4x)/2

b) 16 cm^2

Step-by-step explanation:

Let the base of the triangle be x cm

since it is longer, then the height would be (x-4) cm

Mathematically, the area of a triangle is the product of the base and the height divided by 2

So, we have this as;

A = 1/2(x-4)x

A = x(x-4)/2

A = (x^2 - 4x)/2

A =( x^2 -4x)/2

To find the area, we only need to substitute 8 cm for x

we have this as;

A = (8^2 -4(8))/2

A = (64-32)/2 = 32/2 = 16 cm^2

We will begin by converting the word problem to relatable mathematical expression in the first part, in the second part, we will substitute for x and find the area which is 48cm^2

Given data

Let the height be x cm

and let the base be y cm

Going by the word problem statement "base that is 4cm longer than its height."

y = x+4

a. the polynomial expression for the area of the triangle is

We know that the area of triangle is given as

Area = 1/2*Base*Height

Area = 1/2*(x+4)*x

Area = 1/2*x^2+4x

Simplify

Area = x^2/2 + 2x

b. The Area when the height is 8cm

We will substitute x= 8cm

Area = (8)^2/2 + 2(8)

Area = 64/2 +  16

Area = 32+16

Area = 48 cm^2

Answer:

10 1/4

Step-by-step explanation:

Carls age = 12 5/6 - 1 1/3

12 5/6 - 1 1/3

11 (5 - 2) / 6 = 11 3/6

Jane's age = carl's age - 1 1/4

11 3/6 - 1 1/4

10 (12 - 6) / 24 = 10 6/24 = 10 1/4

Answer:

What?

Step-by-step explanation:

Answer: (d)

Step-by-step explanation:

Given

Price  of the stock is given by the function

[tex]P=10e^{km}[/tex]

after 4 months, price increases to $14.60

Insert the value in the function

[tex]\Rightarrow 14.60=10e^{4k}\\\\\Rightarrow 1.46=e^{4k}\\\text{Taking natural log both sides}\\\Rightarrow \ln 1.46=\ln e^{4k}\\\Rightarrow 0.378=4k\\\Rightarrow k=0.0946\approx 0.095\ \text{per month}[/tex]

hence, option (d) is correct.
