Answer:
-4 , -29
Step-by-step explanation:
The values of a and b that make the equation true are -28 and -9, respectively
How to determine the true values of a and b?The equation is given as:
(4 + √-49) – 2((-4)² + √–324) = a + bi
Evaluate the exponents
(4 + 7i) – 2(16 + 18i) = a + bi
Expand the bracket
4 + 7i – 32 - 16i = a + bi
Collect like terms
4 – 32 + 7i - 16i = a + bi
Evaluate like terms
-28 -9i = a + bi
By comparison, we have:
a = -28 and b = -9
Hence, the values of a and b that make the equation true are -28 and -9, respectively

Lines c and d are intersected by line p. At the intersection of lines c and p, the bottom left angle is (3 x + 45) degrees. At the intersection of lines d and p, the uppercase left angle is 81 degrees.

The value of x so that lines c and d are parallel lines cut by transversal p is 12
Angles and transversalsFrom the given figure, the sum of the given angles is supplementary, that is:
3x + 45 = 81
Subtract 45 from both sides
3x + 45 -45 = 81 - 45
3x = 36
x = 12
Hence the value of x so that lines c and d are parallel lines cut by transversal p is 12

Answer:
A =72 in^2
When dilated
=1152 in ^2
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh
We need to convert the units to match
2 ft= 24 inches
A = 1/2 ( 24*6)
A = 1/2 (144)
A =72 in^2
When dilated 6 inches *4 = 24 inches
24 inches *4 = 96 inches
A = 1/2 ( 96*24)
= 1/2(2304)
=1152 in ^2

\sqrt 11 = 3.3
Simplify. 4√−99
Enter your answer, in simplest radical form, in the box.
Answer:
Not sure on this but I'm pretty sure its 12i√11 since you have to use an imaginary number in order for the equation to work.
By simplifying the expression 4√−99, we have; 12i√11.
To simplify 4√−99, we first need to simplify the number present within the square root.
To do this, the factors are determined as follows;
4 × √9 × √-11We can therefore find the square root of 9 so that we have;
4 × 3 × √-11.4 × 3 × √-1112 × √-11Furthermore, √-11 can be rewritten as;
√-1 × √11.However, in complex numbers, √-1 = i.
Ultimately, we have 12i√11 as the simplification of 4√−99.

What is the equation of the line that is perpendicular to y equals negative four x plus five and passes through the point four comma negative three ?
Answer:
y= 1/4x - 4
Step-by-step explanation:
use point slope form which is:
y - y1 = m(x - x1)
we know that the slope will be 1/4 because perpendicular is a negative reciprocal.
plug everything into point slope form:
y + 3 = 1/4 ( x - 4)
we distribute the 1/4 and then subtract the three and we get our answer
y= 1/4x - 4

Answer:
D
Step-by-step explanation:
the answer you chose is correct because if you isolate x (shown below), you end up with -5. there is also no equal sign under the less than symbol, so that means it is an open circle, which it is. however, you must flip the sign when multiplying or dividing by a negative number in inequalities, so this becomes a greater than symbol, showing that x is greater than -5. this accurately portrays the given inequality on the number line.

What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
Given the nth term of a sequence to be b(n)=b(n-1)+1, where n is the number of terms of the sequence
If b(1) = 16... (1)
The second term of the sequence is generated for n= 2:
b(n)=b(n-1)+1
b(2)=b(2-1)+1
b(2) = b(1)+1... (2)
Substituting equation 1 into 2
b(2) = b(1)+1
b(2) = 16 + 1 = 17
Hence, The second term in the sequence is 17.

The value of f(g(0)) is 1.
What is Composition of Functions?Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).
h(x) is called the composite function.
Given a table which shows values for the two functions f and g for different values of x.
We have to find the value of f(g(0)).
f(g(0)) = f[ g(0)]
From the table, g(0) = -1.
f(g(0)) = f(-1) = 1
Hence the value of f(g(0)) is 1.
