Write a quadratic function to model the graph to the right

Mathematics
1 answer:
Komok [63]3 years ago
6 0

Answer:

y = x² + 2x + 5

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here the vertex = (- 1, 4), thus

y = a(x + 1)² + 4

To find a substitute (0, 5) a point on the graph into the equation

5 = a(0 + 1)² + 4

5 = a + 4 ( subtract 4 from both sides )

a = 1, thus

y = (x + 1)² + 4 ← expand and simplify

  = x² + 2x + 1 + 4

  = x² + 2x + 5

The expression i/pt represents the rate of instrest being charged if a loan of p dollars for t years required i dollars in intre
zysi [14]

Answer:

7.3%

Step-by-step explanation:

Given:

<em>Formula for Rate of interest </em>R:

R=\dfrac{i}{Pt}

Where i is the rate of interest.

P dollars is the loan and

t years is the time for which interest is to be paid

P =\$690\\t=3\ years\\i=\$151.11

To find:

R=?

Solution:

Putting the given values in the formula:

R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073

Multiply the above value with 100 to find the percentage.

i.e.

R=0.073\times 100 = \bold{7.3\%}

Therefore, the answer is <em>7.3%</em>

In triangle ABC, m&lt;A = 8x +12, m&lt;B = 5x+14, m&lt;C = 2x +4. What is the m&lt;A ? Need help....please
Elena L [17]
Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
    x = 10

m<A   </span><span>= 8x +12
</span>m<A   = 8(10) +12
m<A = 80 + 12
m<A = 92

answer
m<A = 92
