The value of the given equation is 12.

In order to solve this question, the BODMAS rule would be used. The BODMAS rule gives the order in which mathematical operations can be solved. The order is:

In the numerator:

the addition would be done first: 3² + 1 = 9 + 1 = 10

Then the subtraction would be done next = 14 - 10 = 4

Now determine the square of the term in the bracket : 4²= 16

In the denominator:

The multiplication would be solved first: 3 x 1/4 = 3/4

The next step is  to solve the division : 1 ÷ 3/4 = 1 x 4/3 = 4/3

The fraction becomes : 16 ÷ 4/3

16 x 3/4 = 12

The values of the angles m∠1 and m∠3 is equal to 73°.

A transversal may be defined as a line which cuts a pair of parallel lines and forms several angles. When transversal cuts parallel lines the alternate interior angles are equal as well as the corresponding angles are equal. Also, the pair of vertically opposite angles are equal. From the figure attached. ∠4 = ∠8 as they are corresponding angles. So, m∠8 = m∠4 = 107°. Now, we know that ∠1 and ∠4 formed a pair of linear angles and the sum of the measures of the linear angles is 180°. So,

m∠1 + m∠4 = 180°

We know, m∠4 = 107°

m∠1 = 180° - 107°

m∠1 = 73°

Now, ∠1 and ∠3 are vertically opposite angles, so they are equal as the parallel lines are cut by transversal. Therefore, m∠1 = m∠3

=> m∠1 = 73°

=> m∠3 = 73°

The percent discount the card gives can be:

4% or 96%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Royal card for discount.

Multiplying the total price to pay with 0.96 means two cases.

0.96 = 96/100 = 96%

Cases 1:

If the percent discount is 96% we will multiply the total prices to pay by 0.96 and subtract the value from the total price.

Example:

Total price to pay = 100

0.96 x 100 = 96

Total price to pay = 100 - 96 = 4

Cases 2:

If the percent discount is 4% we will multiply the total prices to pay by 0.96 after subtracting 4% from 100%.

Example:

Total price to pay = 100

Discount = 4%

100% - 4% = 96%

96% = 0.96

Total price to pay = 0.96 x 100 = 96

Thus,

Answer: b = 3.5, h = 4

Step-by-step explanation: a = 1/2bh, area of a triangle formula

7 = 1/2((b)(2b-3)) state h in terms of b

7 = 1/2(2b^2-3b) simplify

7 = b^2 - 1.5b simplify

b = 3.5 final answer

Then, solve for h.

h = 7 - 3 substitute

h = 4 final answer

hope this helps!

Step-by-step explanation:

area of a triangle

base × height / 2

in our case

base × height / 2 = 7

base × height = 14

height = 2×base - 3

we can use the last identity in the area equation and get

base × (2×base - 3) = 14

2×base² - 3×base - 14 = 0

the solution to a quadratic equation like

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

base = (3 ± sqrt((-3)² - 4×2×-14))/(2×2) =

= (3 ± sqrt(9 + 112))/4 = (3 ± sqrt(121))/4 =

= (3 ± 11)/4

base1 = (3 + 11)/4 = 14/4 = 7/2 = 3.5 in

base2 = (3 - 11)/4 = -8/4 = -2

negative numbers for sizes of physical objects don't make sense, so, base = 3.5 in is our solution.

height = 2×base - 3 = 2×3.5 - 3 = 7 - 3 = 4 in

base length = 3.5 in

height = 4 in

The function has an average rate of change f is 1/2 over the interval

The possible graph that completes the question is added as an attachment

The interval is given as

-3 ≤ x ≤ 9

This can be rewritten as

x = -3 to x = 9

This can also be represented as

(a, b) = [-3, 9]

From the attached graph, we have

f(-3) = -1.5

Also, we have

f(9) = 0.5

The estimate (to one decimal place) of the average rate of change f is calculated as

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [f(9) - f(-3)]/[9 + 3]

So, we have

Rate = [0.5 + 1.5]/[9 + 3]

Evaluate

Rate = 2/12

Simplify

Rate  = 1/6

Using addition of polynomials, the function modeling the number of people attending degree-granting institutions is:

M(t) = 19.7t² + 310.5t + 7539.6.

The number of females is given by:

F(t) = 28t² + 368t + 10127.8.

The total number is given by the addition of the number of males and of females, that is:

P(t) = M(t) + F(t).

Which is an addition of polynomials. To add the polynomials, we combine the like terms, that is, adding the terms that have the same variable and exponent. Hence:

P(t) = M(t) + F(t).

P(t) = 19.7t² + 310.5t + 7539.6 + 28t² + 368t + 10127.8.

The acceleration is 4.24 m^2/s

They are accelerations and vector quantities. The direction of an object's acceleration is determined by the direction of the net force acting on it. Acceleration describes the rate at which a speed changes over time.

The velocity is changing over time. The velocity is actually changing at a constant rate of 10 m/s per second. If an object's velocity is changing, it is said to be accelerating; it has acceleration.

According to question,

Acceleration = final velocity- initial velocity/ time

Final velocity = 14.8 and initial velocity = 4.2

Hence, acceleration = 14.8-4.2/2.5

=10.6/2.5

=4.24.
