At the beginning of 2009 Marilyn invested $5000 in a savings account account pays 4% interest per year at the end of the year at the interest is paid how much does Marilyn have in the account?
Answer:
$5200
Step-by-step explanation:
Given :
Amount invested, Principal, P = $5000
Interest rate, r = 4% = 4/100 = 0.04
Amount in account at the end of the year, A
period, t = 1 year
Using the relation :
A = P(1 + rt)
A = $5000(1 + 0.04*1)
A = $5000(1 + 0.04)
A = $5000 * 1.04
Amount in account at year end = $5200

Find all real and non-real roots of the function ƒ(x) = x2 + 49. Question 1 options: A) x = –7, 7 B) x = –7i, 7i C) x = –49i, 49i D) x = i + 7, i – 7
Answer:
B
Step-by-step explanation:
f(x) = x²+49 , rewrite the equation
x² +7² =0 , to find the roots make f(x) =0 and subtract 7² from both sides
x² = -7², square root both sides
√x² =√-7², consider √-1 =i
x= ±7i
the roots are -7i and 7i
Answer:
B
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
x² + 49 = 0 ( subtract 49 from both sides )
x² = - 49 ( take the square root of both sides )
x = ± [tex]\sqrt{-49}[/tex] = ± 7i
Solutions are x = - 7i, x = 7i

Since the x's both are to a power and have exponents outside of the parenthesis, we multiply the inner exponent by the outer exponent.
x^-150 / x^-144
Then, we need to move the bottom term to the top so that we have no negative exponents. Now, we are technically subtracting, but subtracting a negative is the same thing as adding.
x^(-150 + 144)
x^-6
Hope this helps!
Answer:
so your answer is -6
Step-by-step explanation:
[tex]\frac{(x^2^5)^-^6}{(x^-^3)^4^8}[/tex] Did i write the equation right? If so you would multiply the exponents
x^-150 x^144
---------- so you then flip the two and get ----------
x^-144 x^150
then you would subtract the exponents like this 144-150= -6

Here is a circle, centre 0, and the tangent to the circle at the
point (-7, 24) on the circle.
Find an equation of the tangent at the point P.
Give your answer in the form y = ax + b where a and b are both
fractions with denominator 24.
Answer:
[tex] y = \dfrac{7}{24}x + \dfrac{625}{24} [/tex]
Step-by-step explanation:
The radius drawn to the tangent at the point of tangency is perpendicular to the tangent.
The radius has endpoints (0, 0) and (-7, 24). The slope of the line containing the radius is
[tex] m_r = \dfrac{24 - 0}{-7 - 0} [/tex]
[tex] m_r = -\dfrac{24}{7} [/tex]
The slope of the tangent is the negative reciprocal of the slope of the radius.
[tex] m_t = \dfrac{7}{24} [/tex]
The tangent contains point (-7, 24).
y = mx + b
[tex] 24 = \dfrac{7}{24}(-7) + b [/tex]
[tex] 24 = -\dfrac{49}{24} + b [/tex]
[tex] \dfrac{576}{24} + \dfrac{49}{24} = b [/tex]
[tex] b = \dfrac{625}{24} [/tex]
The equation of the tangent is
[tex] y = \dfrac{7}{24}x + \dfrac{625}{24} [/tex]
An equation of the tangent at the point P is y=7/24 x+625/24.
Given that, here is a circle, center O, and the tangent to the circle at the point (-7, 24) on the circle.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The radius drawn to the tangent at the point of tangency is perpendicular to the tangent.
The radius has endpoints (0, 0) and (-7, 24). The slope of the line containing the radius is m= (24-0)/(-7-0)
= -24/7
The slope of the tangent is the negative reciprocal of the slope of the radius.
So, slope =7/24
The tangent contains point (-7, 24), so 24=7/24 (-7)+24b
⇒ 576=-49+24b
⇒ b=625/24
Now, with m=7/24 and b=625/24, we have
y=7/24 x+625/24
Therefore, an equation of the tangent at the point P is y=7/24 x+625/24.

A tourist has TT $7875. She spends TT $2310 and changed the remaining Trinidad and Tobago currency to Canadian currency. Calculate the amount of money she received if the rate is CAN $1.00 = TT $3.5 *
Answer:
CAN $1590
Step-by-step explanation:
Below is the given values:
Tourist has money = TT $7875
Spending = TT $2310
Remaining money = 7875 - 2310 = TT $5565
The Canadian currency she has = TT $5565 / TT $ 3.5
The Canadian currency she has =CAN $1590
The amount of money she will receive after converting into Canadian dollars = CAN $1590
Solve system by elimination -9x - y =-19
5x + y = 15
Answer:
(1, 10 )
Step-by-step explanation:
Given the 2 equations
- 9x - y = - 19 → (1)
5x + y = 15 → (2)
Adding the 2 equations term by term will eliminate the y- term
- 4x + 0 = - 4
- 4x = - 4 ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
5(1) + y = 15
5 + y = 15 ( subtract 5 from both sides )
y = 10
solution is (1, 10 )
Ricardo llega cada mañana a su trbajo con 5 minutos de retraso. Cúanto dinero le descuentan al cabo de 30 dIas si por cada hora tiene una multa de s/2,80
Respuesta:
7
Explicación paso a paso:
Dado :
Último minuto por día = 5 minutos
Número de retrasos = 3 días
Número total de minutos tarde = (30 * 5) = 150 minutos
Cargo por multa por pago tardío por hora = 2,80
Total de horas tardías = 150 minutos / 60 = 2,5 horas
Cargo total por multa por mora = 2.80 * 2.5
Cargo total por multa por mora = 7

measure of each labeled angle
Answer:
[tex]\sf m\angle A = 3x - 20^o = \bf 100^o [/tex]
[tex]\sf m\angle B = 2x = \bf 80^o [/tex]
[tex]\sf m\angle C = 2x - 15^o = \bf 65^o [/tex]
Step-by-step explanation:
A figure is given to us , in which two lines are parallel to each other. There are two transversals to the || lines . We know that the measure of a straight line is 180° . Therefore ,
[tex]\sf\longrightarrow \angle A +\angle B = 180^o [/tex]
Substitute the given values ,
[tex]\sf\longrightarrow 3x - 20^o + 2x = 180^o [/tex]
Simplify the RHS by adding the variables ,
[tex]\sf\longrightarrow 5x - 20^o = 180^o [/tex]
Add 20° to both sides ,
[tex]\sf\longrightarrow 5x = 180^o + 20^o [/tex]
Add the numbers in RHS ,
[tex]\sf\longrightarrow 5x = 200^o [/tex]
Divide both sides by 5 ,
[tex]\sf\longrightarrow \boxed{\blue{\sf x = 40^o}}[/tex]
Therefore ,
[tex]\sf m\angle A = 3x - 20^o = \bf 100^o [/tex] [tex]\sf m\angle B = 2x = \bf 80^o [/tex] [tex]\sf m\angle C = 2x - 15^o = \bf 65^o [/tex]if x = 2 is a solution to the system shown below, then what must be value of b?

3 hours after starting a trip, a driver increased his speed by 10 mph and arrived at his destination 11 hours after starting his journey. If the distance traveled was 894 miles, find the original speed of the driver.
Answer:
74 mph
Step-by-step explanation:
The driver started driving at s mph.
After 3 hours, the speed became s + 10 mph.
The total time is 11 hours, so 3 hours were driven at s mph and 8 hours were driven at s + 10 mph.
speed = distance/time
distance = speed * time
distance = (distance driven at speed s) + (distance driven at speed s + 10)
894 = s * 3 + (s + 10) * 8
3s + 8s + 80 = 894
11s + 80 = 894
11s = 814
s = 74
Answer: 74 mph
For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and
determine the y-intercept. Decide which table best illustrates these values for the equation:
f(x) = 9x^2 + 5x + 3
Answer:
Table (C)
Step-by-step explanation:
Given equation of the parabola is,
f(x) = 9x² + 5x + 3
By comparing this equation with,
f(x) = ax² + bx + c
a = 9, b = 5 and c = 3
Since, leading coefficient (a) of the function is positive,
Parabola will open upwards.
For y-intercept,
Substitute x = 0 in the equation,
f(0) = 9(0)² + 5(0) + 3
f(0) = 3
Therefore, y-intercept is (0, 3).
Table (C) is the answer.
