Given the function C(t) = (t – 6)(t + 1)(t – 7)
its C-intercept is=
I
its t-intercepts are =
Answer:
The c intercept is 42
The t intercepts are: 6, -1 and 7
Step-by-step explanation:
Given
[tex]c(t) = (t - 6)(t +1)(t-7)[/tex]
Solving (a): The c intercept
Simply set t to 0
[tex]c(t) = (t - 6)(t +1)(t-7)[/tex]
[tex]c(0) = (0 - 6)(0 +1)(0-7)[/tex]
[tex]c(0) = (- 6)(1)(-7)[/tex]
[tex]c(0) = 42[/tex]
Solving (b): The t intercept
Simply set c(t) to 0
[tex]c(t) = (t - 6)(t +1)(t-7)[/tex]
[tex](t - 6)(t +1)(t-7) = 0[/tex]
Split
[tex]t - 6= 0,\ \ t +1= 0,\ \ t-7 = 0[/tex]
Solve for t
[tex]t = 6,\ \ t =-1,\ \ t=7[/tex]

I don’t understand how to do this.
Answer:
46degrees
Step-by-step explanation:
From the question, we are told that both triangles are similar, hence;
<E = <S
<D = <R
<F = <T
From triangle DEF
<D + <F + <E = 180
Since <D = <F = 67
67 + 67 + <E = 180
134 + <E = 180
<E = 180 - 134
<E = 46degrees
Since <E = <S, hence the measure of <S is 46degrees
The distance between major cracks in a highway follows an exponential distribution with a mean of 5 miles. (a) What is the probability that there are no major cracks in a 10-mile stretch of the highway
Answer:
[tex]P(Y=0) = 0.1353[/tex]
Step-by-step explanation:
From the question we are told that:
Exponential distribution mean [tex]\=x = 5 miles[/tex]
Distance [tex]d=10miles[/tex]
Generally the equation for Exponential distribution is mathematically given by
[tex]\lambda=\frac{1}{E(X)}[/tex]
[tex]\lambda=\frac{1}{5}[/tex]
Therefore
Possion Y
[tex]10\lambda=10*(1/5)[/tex]
[tex]10\lambda=2[/tex]
Generally the equation for The probability that there are no major cracks in a 10 mile stretch of the highway is mathematically given by
[tex]P(Y=0) = \frac{e-2 (2)0}{0!}[/tex]
[tex]P(Y=0) = e-2[/tex]
[tex]P(Y=0) = 0.1353[/tex]
0. 1. 9. In Sujata asked 100 coffee drinkers whether they like cream or sugar in their coff According to Venn diagram below, how many like. (a) Cream (b) Sugar (c) Sugar but not cream (d) Cream but not sugar (e) Cream and sugar (f) Cream or sugar
Answer:
36, 55 , 35, 16, 20, 71
Step-by-step explanation:
Total number of coffee drinkers, U = 100
Let
n(Cream) = C
n(Sugar) = S
n(cream and sugar) = n(CnS) = 20
Number that like cream = n(C) + n(CnS) 16 + 20 = 36
Nunber that like sugar = n(S) + n(CnS) = 35 + 20 = 55
Sugar but not cream = 35 (from. Venn diagram)
Cream but not sugar = 16 (From. Venn diagram)
Cream and sugar = n(CnS) = 20
Cream or sugar = n(CuS) = 16 + 20 + 35 = 71

help plsss it’s timed i need to passss plsss
Answer:
65°
Step-by-step explanation:
To obtain Angle A, we use the cosine rule ;
Cos A = (b² + c² - a²) / 2bc
Cos A = (12² + 14² - 14²) / 2(12)(14)
Cos A = 144 / 336
A = Cos^-1(144/336)
A = 64.62°
A = 65°

According to the Question,
Given That, Let V be the set of all 3x3 matrices with Real number entries, with the usual definitions of scalar multiplication and vector addition. Consider whether V is a vector space over C.For V is a vector space over C and V is Set of 3x3 Matrices with Real entries.Then, For any u,w ∈ V ⇒ u+w ∈ V
And u∈V and z∈C ⇒ z u ∈ V
So, If we take any z= i ∈ C
and V be any 3x3 matrices with Real entrices.then, z,v ∉ V ∴z,v Has Complex entries
So, the Scalar Closure axiom is not satisfied
Hence, V is not a Vector Space of C
Any u,w ∈ W ⇒ u+w ∈ V
So, The Additive Closure axiom is satisfied.

Answer:
x = 8
y = 6
Step-by-step explanation:
Recall that one of the properties of a parallelogram is that the diagonals bisect each other, which means they divide each other into equal segments.
Therefore,
LP = PN
x = y + 2 (eqn. 1)
PM = KP
2x - 8 = y + 10 (eqn. 2)
Substitute x = y + 2 into eqn. 2 to find y
Thus:
2(y + 2) = y + 10
2y + 4 = y + 10
Take like terms
2y - y = -4 + 10
y = 6
Substitute y = 6 into eqn. 1 to find x:
x = y + 2 (eqn. 1)
x = 6 + 2
x = 8

(Show full work please) Carter spots an airplane on radar that is currently approaching in a straight line, and
that will fly directly overhead. The plane maintains a constant altitude of 7250 feet.
Carter initially measures an angle of elevation of 16 to the plane at point A. At some
later time, he measures an angle of elevation of 26° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary
Consult the attached diagram.
In the larger triangle,
tan(16°) = (7250 ft) / (x + y)
and in the smaller triangle,
tan(26°) = (7250 ft) / y
You want to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft), you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))
x ≈ 10,433 ft
The distance the plane traveled from point A to point B is 10,433 ft.
We have given that,
Carter spots an airplane on the radar that is currently approaching in a straight line, and that will fly directly overhead.
The plane maintains a constant altitude of 7250 feet.
In the larger triangle,tan(16°) = (7250 ft) / (x + y)and in the smaller triangle,
What is the tan ratio?[tex]tan(\ theta)=\frac{\\opposite \side }{hypotenouse}[/tex]tan(26°) = (7250 ft) / y
we have to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft),
you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))x ≈ 10,433 ft
Therefore the distance the plane traveled from point A to point B is 10,433 ft.

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 25%, and the final exam is worth 27%. Compute the weighted average for the following scores: 74 on the lab, 69on the first major test, 62 on the second major test, and 85 on the final exam. (Enter your answer to one decimal place.)
Answer:
72.7 is the weighted average score
Step-by-step explanation:
The weighted average score
= score of lab * % share of total grade + score of first major test * % share of total grade + score of second major test * % share of total grade + Score of the final exam * % share of total grade
Substituting the given values, we get -
0.23 * 74 + 0.25 * 69 + 0.25 * 62 + 0.27 * 85
= 72.7

What is the future value of a R 75 000 deposit made every 6 months for 3 years using an annual rate of 10% compounded semi-annually?
Answer:
The future value is: RS 132867.075
Step-by-step explanation:
Given
[tex]PV = 75000[/tex] --- present value
[tex]r = 10\%[/tex] --- annual rate
[tex]n = 6[/tex] --- number of times compounded (3 years/ 6 months)
Required
The future value
This is calculated as:
[tex]FV =PV * (1 + r)^n[/tex]
[tex]FV = 75000 * (1 + 10\%)^6[/tex]
[tex]FV = 75000 * (1 + 0.10)^6[/tex]
[tex]FV = 75000 * (1.10)^6[/tex]
[tex]FV = 132867.075[/tex]
Hence, the future value is: RS 132867.075
