Answer:

Sarah had 16 stickers. Al gave her 25 more. How many stickers does Sarah have now? 41

Step-by-step explanation:

Answer: 41

Step-by-step explanation: The key word in this sentence is more. She already has 16 and she is getting another 25. So that means you have to add 16 and 25 to find out how much she has now. The answer would be 41.

Find the value of n for which the vectors a⃗ =(3,2)a→=(3,2) and b⃗ =(9,n)b→=(9,n) are collinear.​

Answers

Answer:

For n=6, the given vectors will be collinear.

Step-by-step explanation:

Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.

Given

[tex]a = (a_1, a_2) = (3,2)\\b = (b_1, b_2) = (9,n)[/tex]

The ratio of first unit vectors is:

[tex]\frac{a_1}{b_1} = \frac{3}{9} = \frac{1}{3}[/tex]

In order for the vectors to be collinear the other ratio should also be 1/3

[tex]\frac{a_2}{b_2} = \frac{1}{3}[/tex]

Writing it mathematically

[tex]\frac{2}{n} = \frac{1}{3}\\2*3 = n\\n = 6[/tex]

Hence,

For n=6, the given vectors will be collinear.

Two lines are perpendicular. The slope of the first line is. What is the slope of the second line?

Answers

Answer:

Therefore, the slope of the original line is 1/2. A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line.

The vertex angle of an isosceles triangle is 10 less than three times the base angles. Find each angle of the triangle.

Answers

3b-10

(3x-10) +2x=180
5x -10=180
5x=190
x=38.

3(38)-10= 104

vertex angle is 104 degrees and each base angle is 38 degrees

From the picture attached,

ΔABC is an isosceles triangle.

       ∠B ≅ ∠C

Vertex angle ∠A is 10 less than 3 times the base angles.

       m(∠A) = 3[m(∠B)] - 10

By applying angle sum theorem in ΔABC,

m(∠A) + m(∠B) + m(∠C) = 180°

m(∠A) + m(∠B) + m(∠B) = 180° [From equation (1)]

m(∠A) + 2m(∠B) = 180°

[3m(∠b) - 10] + 2m(∠B) = 180°

5[m(∠B)] = 180° + 10°

m∠B = 38°

       Therefore, m∠B = m∠C = 38°

Substitute the value of angle B in equation (2),

m(∠A) = 3[m(∠B)] - 10

m(∠A) = 3(38) - 10

          = 104°

        Therefore, measure of angle A will be 104°.

A new drug on the market is known to cure 30% of patients with cervical cancer. If a group of 18 patients is randomly selected, what is the probability of observing, at most, one patient who will be cured of cervical cancer?

Answers

Answer:

Probability cured of cervical cancer =  18C0 (0.30)⁰(0.70)¹⁸ +  18C1(0.30)(0.70)¹⁷

Step-by-step explanation:

Given:

Patients cured = 30% = 0.30

Number of patients (n) = 18

Probability cured of cervical cancer = P(X≤1)

Probability cured of cervical cancer  = P(X=0) + P(X=1)

Probability cured of cervical cancer =  18C0 (0.30)⁰(0.70)¹⁸ +  18C1(0.30)(0.70)¹⁷

Find an equation of the sphere that passes through the point (6, -2, 3) and has center (-1, 2, 1). Find the curve in which the sphere intersects the yz-plane. Find the center and radius of the sphere

X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0

Answers

Answer:

A)  x^2 + 2x+ y^2 - 4y + z^2 - 2z - 63 = 0

B) radius = 5

center  = (4,-1,-3)

Step-by-step explanation:

[tex]x^2 + y^2 + z^2 - 8x + 2y + 6z + 1 = 0[/tex]

A ) Determine the curve in which the sphere intersects the yz-plane

determine the radius ( r ) =  √((6-(-1))2+(-2-2)2+(3-1)2) = √69

next the equation of the sphere ( curve in which the sphere intersects the yz-plane )

x^2+2x+y^2-4y+z^2-2z-63 = 0

B) determine the center and radius of the sphere

X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0

(x-4)2+(y+1)2+(z+3)2 = 25 = 52

radius = 5

32. Parallelogram ABCD has vertices A(0,0), B(2,4), and C(10,4). Find the coordinates of D.
Answer:

Answers

Answer:

The fourth vertex is D(8, 0)

Step-by-step explanation:

Let A(0, 0), B(2, 4), and C(10, 4) be the three vertices of a parallelogram ABCD and let its fourth vertex be D(a, b).

Join AC and BD. Let AC and BD intersect at point O.

We have known that the diagonals of a parallelogram bisect each other.  

So, O would be the midpoint of AC as well as that of BD.

[tex]A\left(0,\:0\right)=\left(x_1,\:x_2\:\right)[/tex]

[tex]C\left(10,\:4\right)=\left(x_2,\:x_2\:\right)[/tex]

The midpoint of AC is:

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:4\right)[/tex]

[tex]=\left(\frac{10+0}{2},\:\frac{4+0}{2}\right)[/tex]

[tex]=\left(5,\:2\right)[/tex]

The midpoint of BD is:

[tex]=\left(\frac{a+2}{2},\:\frac{b+4}{2}\right)[/tex]

so

∵  [tex]\frac{a+2}{2}=5[/tex]

[tex]a+2=10[/tex]

[tex]a=8[/tex]

∵ [tex]\frac{b+4}{2}=2[/tex]

[tex]b+4=4[/tex]

[tex]b=0[/tex]

Hence, the fourth vertex is D(8, 0)
